Product DESCRIPTION
UVS 40A2
HIGH INTENSITY UV SOURCE
DESCRIPTION
The UV Source (UVS) is a high intensity photon source that can be operated with a variety of discharge gases. The UVS 40A2 is used in UPS (ultraviolet photoelectron spectroscopy) research. The UVS is water cooled for maximum stability and features fully interlocked safety circuitry. The discharge has a maximum photon intensity at a pressure of several mbar so dual differential pumping stages are employed in order to maintain the host chamber pressure. The UVS 40A2 is designed so that a continuous gas flow is maintained through the discharge region. This is a great advantage in maintaining the cleanliness of the discharge capillary and results in very long service intervals.
FEATURES
· Can be operated with various discharge gases
· Manual or auto ignition

· Differential pumping (required)
· Chiller
UV40A-PS
UV SOURCE POWER SUPPLY
DESCRIPTION
The UV40A-PS can work in either constant discharge current or discharge voltage mode to provide the best operation conditions for the UV source. The source can be automatically ignited directly from the power supply or manually on the source via a piezo-electric igniter. All adjustable parameters are clearly displayed on the large front-panel TFT and precisely controlled via digital encoders. The unit also features a built-in timer and automatic standby mode. The UV 40A-PS is supplied as a full width 19’’ rack mounting unit (3U height). Easy firmware update via USB port. The unit can be remotely controlled via RS232/485 or Ethernet interfaces. The unit is equipped with autosave function (the device saves your parameters, preset and apply them automatically
after restart).
APPLICATION
The UV40A-PS power supply controls the UV40A1 UV Source in ultraviolet photoelectron spectroscopy (UPS) applications.
OPTIONS
· Analog I/O card for vacuum measurement (1 gauge)
