`GENERAL INFORMATION
`Safety
`WARNING
`
`This unit emits ultraviolet (UV) radiation that is
`harmful to humans. Avoid exposure to the
`direct or reflected output beam. Make certain
`that the appropriate output beam shields and
`optics are in place prior to energizing the unit.
`All
`interlocks must be satisfied prior
`to
`operation; failure to do so may
`lead to
`hazardous conditions.
`
`CAUTION
`
`levels of UV
`The EQ-99 emits dangerous
`radiation. Even short exposures to skin or eyes
`may cause burns. Ensure that only authorized
`personnel are in the vicinity of source during
`operation. Personnel in vicinity of operating
`source should wear protective eyewear, clothing,
`and gloves. Lighted UV warning lights and signs
`posted on doors to lab areas may help prevent
`accidental exposure.

`

`
`WARNING
`
`The EQ-99 controller utilizes an internal Class 4
`IR laser capable of causing severe injury to eyes
`or skin. Do not open or attempt to service this
`unit. Contact Energetiq regarding any problems
`with the unit.
`
`
`
`
`
`General Precautions
`The output beam from the EQ-99 should be blocked when not in use with an electronic
`shutter or other appropriate beam blocking device. Due to the possibility of generating ozone
`when ambient oxygen is exposed to short wavelength light, the beam should always be
`enclosed in an appropriate beam pipe, tube, or enclosed space. We suggest purging any beam
`transport space with dry nitrogen gas.
`
`The EQ-99 source must also be cabled correctly and connected to a socket with a protective
`earth ground prior to operation.
`
`Refer to the Installation section of this manual in Chapter 3 for details of the facilities
`connections.
`
`Other than a bulb replacement, there are no user-serviceable parts inside the EQ-99. For any
`problems encountered during operation, please contact Energetiq Technology for assistance.
`If there is a component failure, do not attempt to open the Power Supply Controller or
`Lamp House enclosure of the EQ-99.
`
`The EQ-99 utilizes a quartz lamp containing a high-pressure gas fill. Explosion of the
`
`lamp and possible injury from flying fragments can occur if the lamp is mishandled.

`
`

`
`Do not open the enclosure of either the Lamp House enclosure or the Power Supply
`
`Controller. Dangerous invisible infrared laser beams and hazardous voltages exist
`inside the units. Opening the chassis both voids the warranty and exposes the user to
`dangerous radiation and hazardous voltages.
`
`
`
`CAUTION
`
`Use of controls or adjustments or performance of procedures
`other than those specified herein may result in hazardous
`radiation exposure.
`
`
`
`Laser Information
`The EQ-99 uses a patented (U.S. Patent #7,435,982, others pending) laser drive system to
`excite a plasma that radiates in the UV as well as the visible bands. A class 4 laser is located in
`the Power Supply Controller enclosure. Laser energy is delivered via an armored fiber to the
`Lamp House enclosure and connected with an SMA-type connector. Safety interlocks shut
`down the laser power if the SMA connector is removed from the Lamp House enclosure. The
`optical configuration of the Lamp House ensures that the direct laser beam can not exit the
`unit. The EQ-99 laser product is designated as Class 1 during all normal operation.

`
`
`
`Input/Output (I/O) Connector
`Provides access to control and status signals. See Chapter 3 for pin assignments and functions.
`
`This is the only operator interface to the EQ-99 – there are no local controls. Energetiq offers
`the EQ-99-RC Remote Control Module which connects to the Input/Output connector and
`provides a means of local control. Contact Energetiq for additional information.
`
`Power Input Connector
`This is a latching input connector for 12 VDC power. Power can be provided using the
`optional PS00018 12VDC power supply. Alternatively, the EQ-99 can be powered directly
`from a customer provided 12VDC power supply. See Chapter 3 for detailed information.

`Armored Laser Fiber
`The laser light is delivered from the Power Supply Controller to the Lamp House via a fiber
`optic cable with armored protection. The fiber is permanently attached to the Power Supply
`Controller, and connected to the Lamp House by an SMA-type connector.
`
`It is critical that this armored fiber be treated with care and inspected for any abnormalities
`prior to operation. Avoid sharp bends, which will permanently damage the fiber. Minimum
`bend radius is 30mm (1.18 in). Avoid crimping or compressing the fiber.

`
`

`
`Nitrogen Purge Inlet
`This is the inlet fitting for nitrogen purge gas. Purge gas is optional but is recommended for
`best performance. With no purge, ozone will form from atmospheric oxygen and attenuate
`the light output in the 220 – 280nm band. In addition, atmospheric oxygen and water vapor
`will attenuate the output below 200nm.
`
`There is no return fitting for the purge nitrogen. The purge flow normally escapes within the
`Lamp House enclosure, and then to atmosphere.
`
`Laser Input
`This is the inlet connector for the armored fiber from the Power Supply Controller. It
`contains a set of interlock pins that disable the laser when the SMA connector is not properly
`in place.
`
`Laser On Indicator
`This LED is illuminated when the laser is ON.
`

`INSTALLATION
`
`Unpacking
`Upon arrival, start by inspecting all parts of the system for completeness and any damage
`incurred in shipping. The EQ-99 shipping box should contain:
`
`1) EQ-99 Power Supply Controller unit
`1) EQ-99 Lamp House unit
`1) Black interconnecting cable from Lamp House to Power Supply Controller (9
`pin mini D-sub).
`
`OPTIONAL
`1) EQ-99-RC Remote Control Module with interlock connector
`1) I/O cable with 15 pin D- connector at each end
`1) 12 VDC Power Supply (universal input voltage)
`
`
`Use care when unpacking to avoid damaging the armored fiber optic cable.
`
`If any part is missing or appears damaged, contact Energetiq immediately. Do not attempt to
`substitute any parts. There are no user-serviceable parts inside the EQ-99 Lamp House or
`Power Supply Controller unit.
`
`Connections
`Installation of the EQ-99 consists of connecting electrical and gas supplies, and connecting
`the Lamp House module to the user’s equipment.
`
`Electrical Power
`The EQ-99 requires 12VDC at 11.7A minimum (140W rating). Power consumption is
`approximately 100W during normal operation.
`
`Power can be provided using the optional PS00018 12VDC power supply. Alternatively,
`power can be provided directly via a customer provided 12VDC power supply. The connector

`

`
`on the EQ-99 is a latching connector. Once fully inserted, the connector will not release unless
`the body of the connector is pulled first. This protects from accidental removal of power if the
`power cable is pulled. Connect to a 12VDC source as follows:

`
`
`
`Purge Gas
`Purge gas is optional but is recommended for best performance. With no purge, ozone will
`form from atmospheric oxygen and attenuate the light output in the 220 – 280nm band. In
`addition, atmospheric oxygen and water vapor will attenuate the output below 200nm.
`
`If required, connect a source of nitrogen purge gas to the port on the Lamp House. The
`fitting is a push-to-connect type, sized for 4 mm tubing.
`
`Clean and dry nitrogen from either a dewar or research-grade N2 bottle is recommended. Do
`not use any other purge gas. Grade 6 or better gas purity is recommended to maintain
`cleanliness of the optics, and gas should be filtered to <5um. Supply pressure should be 20
`psig (0.14 MPa). With a 20 psig inlet pressure, the EQ-99 will consume approximately 1 slm of
`flow.
`
`There is no return fitting for the purge nitrogen. The purge flow normally escapes within the
`Lamp House enclosure, and then to atmosphere.
`
`Optical Interface
`The lamp window accommodates a light output of 0.47 NA. A pair of pins and a 6-32
`threaded hole are available for mounting. An internally-threaded SM1 adapter is provided for
`connection of optical hardware. See Figure 5 below for mechanical layout of the Lamp
`House.

`
`Signal Connections
`The EQ-99 is controlled through the remote I/O connector.
`
`Table 3 gives the pin assignments and functions for this interface. Connect to the user’s
`control system using a suitable cable. Mating connector is a standard high-density 15-pin d-
`sub male (for example, Amp part no. 748364-1 with contacts 1658670-2).
`
`Optionally, connect a model EQ-99-RC remote control module to the I/O connector using
`the supplied cable
`
`User I/O can be powered either by the EQ-99 internal isolated power supply, or an external
`supply.
`
`Figure 7 shows connection schematics for both configurations.

`
`
`Installation Procedure
`1. Mount the Power Supply Controller unit rigidly to either an optical breadboard plate
`or another suitable mounting structure using the supplied tabs on the bottom of the
`chassis. The holes are sized to accept standard ¼-20 optical bench hardware, and
`spaced to be compatible with a standard 1” grid mounting hole pattern. See Figure 6
`for dimensional and mounting details.
`Do not block the inlet or outlet air vents of the Power Supply Controller.
`2. Connect the Lamp House unit output to the user equipment. The beam should always
`be either directly coupled to a fiber optic cable, or enclosed in an appropriate beam
`pipe, tube, or enclosed space and purged with nitrogen. Operating the source without
`any output target or beam transport is not recommended, and may lead to unsafe
`operating conditions. Consult Energetiq for applications information and suggested
`configurations.
`The Lamp House should be mounted in the orientation shown in 3, with the output
`window on the side and the flat surface of the housing on the bottom. The lamp has
`been factory aligned in this position. Mounting the lamp in a different orientation will
`cause the plasma position inside the bulb to shift slightly and may cause performance
`problems. If using an optical fiber for the light output, this will result in slight
`misalignment and a resulting drop in output power.
`3. Setup the Lamp House unit with appropriate ultraviolet safety measures and laser light
`safety measures in place. It is recommended that any enclosure or aperture-blocking
`hardware utilize switches wired to the EQ-99 external interlock circuit.
`4. Connect the black 9 pin mini D-sub interconnect cable from the Power Supply
`Controller (labeled TO LAMP) to the Lamp House (labeled J4).
`5. The EQ-99 is delivered with the armored laser fiber connected to the lamp house.
`This is done to minimize the possibility of debris or particles contaminating the end of
`the laser fiber. Energetiq strongly recommends leaving the laser fiber connected, unless
`it is necessary to disconnect it for installation or routing of the laser fiber. If the laser
`fiber must be disconnected, apply SMA caps immediately to both ends, and follow
`directions on inspection and cleaning of the laser fiber described in Chapter 5.
`Use care when handling the fiber optic cable to avoid sharp bends, which will
`permanently damage the cable. Minimum bend radius for the cable is 30mm (1.18 in).
`6. If necessary, connect the SMA connector to the Lamp House laser input and tighten..
`7. If required, connect nitrogen purge gas to the Lamp House. Refer to “Facilities
`Requirements” above.
`8. Connect user’s control system to the I/O interface connector per Table 3 and Figure
`7.

`
`9. Alternately, if using the EQ-99-RC Remote Control Module, place it on a clean rigid
`surface. Install the supplied 15-pin cable from the Power Supply Controller to the
`EQ-99-RC.
`10. Connect 12VDC input power source to the Power Supply Controller.
`
`
`The system is now ready to operate.

`OPERATION
`
`Starting
`Once the lamp is set up properly, verify that all personnel that will be in contact with the lamp
`system are aware of the potential hazards involved. It is the responsibility of the user to verify
`that the lamp is being used safely.
`
`This example assumes the use of the EQ-99-RC Remote Control Module to provide local
`control. If using a custom control system, substitute the appropriate digital input and output
`lines from Table 3 for the switches and LEDs described below.
`
`1. With the EQ-99-RC Remote Control Module connected properly, review the status
`LEDs on the Power Supply Controller. The POWER ON LED should be lit, and
`neither the CONTROLLER FAULT nor LAMP MODULE FAULT LEDs should
`be lit.
`2. Turn on the OPERATE Switch (place switch in UP position).
`3. Within several seconds the LASER ON LED will light. Laser light is now present in
`the Lamp House.
`4. In approximately 20-150 seconds the igniter will be turned on automatically and the
`plasma will ignite. The LAMP ON LED will be lit. The duration of the warm up time
`(20-150 seconds) will depend on the temperature and previous operating condition of
`the EQ-99. The EQ-99 will automatically detect when the unit has reached the
`optimum conditions for ignition.
`5. If a bulb fails to ignite, 150 seconds after the OPERATE switch was activated, the
`LASER ON LED will go out, the LAMP FAULT LED will be lit, and LAMP ON
`LED will remain off. This is very unusual. However, if this occurs, turn the
`OPERATE switch to the OFF position (down) and begin at Step 1 again. If this
`occurs multiple times, contact Energetiq service
`Stopping
`To turn the LAMP off, simply turn the OPERATE Switch to the OFF position. If the lamp
`will not be used for some time, the 12VDC supply can be turned off.

`
`To minimize wear on the ignition components, it is best to avoid frequently starting and
`stopping the lamp. It is recommended to run the lamp continuously if long off-periods are
`not required.

`MAINTENANCE
`
`Fiber Cleaning Process
`
`Fiber Cleaning Basics:
`• The LDLS laser fiber connector is carefully inspected and is clean prior to shipment.
`Energetiq strongly recommends leaving the laser fiber connected, unless necessary for
`installation or routing of the laser fiber.
`• Leave Laser Fiber SMA connected whenever possible.
`•
`If the SMA fiber must be disconnected, always use a metal cap on both ends.
`• Store caps open side down when possible.
`• Blow out caps with CDA (Clean Dry Air) prior to use.
`• Never leave the fiber disconnected without a cap.
`• Follow the fiber inspection and cleaning process (Figure 8) before making a laser fiber
`SMA connection.
`• Operating the LDLS with a contaminated fiber introduces the risk of decreased
`performance or damage to the unit.
