  • Pulse height amplifier/SCA (Canberra 1718)
  • Scintillation preamplifier (Ortec 113)

ANY NON-STANDARD EQUIPMENT OR ADDITIONAL PIECES OF STANDARD EQUIPMENT IN EXCESS OF THE QUANTITY LISTED MUST BE REQUESTED IN ADVANCE.

Equipment for EXAFS Measurements

The equipment listed below is available upon advance request. If it was not included on your original beam time request form it is unlikely that it can be provided due to the over-demand for this equipment.

  • (2) 13-element Ge detector array (Canberra) including electronics.
  • (4) Fluorescence ionization chamber detector ("Lytle Detector") with filters and Soller slits.
  • (3) Continuous flow liquid helium cryostat (Oxford Instruments) for temperatures down to 4K, including turbo pump cart and control system.
  • (4) Motorized EXAFS rail systems, including 3 ion chamber supports, slit support and calibration foil support.
  • (1) 2-3 keV He flight path with slits and ion chamber. Requires motorized rail.
  • (1) Single crystal orientation stage and laser (compatible only with end stations). Requires motorized rail.
  • (1) Grazing incidence x-ray absorption spectroscopy apparatus including motorized slits, motorized optical rail, ion chamber supports, He flight path up to end of first ion chamber; theta grazing angle, vertical sample alignment, ful l phi rotation, 0-90 deg stepwise chi capability; most motions computer controlled.

Standard VUV/Soft X-ray Equipment

The following equipment is standard on all VUV Beam Lines (except 10-1, 3-4, 8-1) and does not need to be requested:

  • MicroVAX II or III running VMS with DSP Technologies CC-Qbus CAMAC Crate Controller and crate
  • Real Time Clock
  • 50 MHz Hex Scaler
  • 16 Bit Digital to Analog Converter (0-10V)
  • Io Monitor (Relative Flux) after monochromator
  • (1) Battery Box (Note: Users may NOT bring their own battery boxes to SSRL)
  • (1) High Voltage Power Supply
  • (1) Current-to-Voltage Amplifier (Keithly 427)
  • (2) Channel Voltage-to-Frequency Converter

VUV Equipment which Must be Requested in Advance

  • Battery Box (if more than one is needed)
  • High Voltage Power Supply (if more than one is needed)
  • Current-to-Voltage Amplifier (if more than one is needed)
  • Multi Channel Linear Amplifier
  • Quad Discriminator
  • Level Adapter
  • Rate Meter
  • 16 Bit Digital-to-Analog Converter (0-10V or -10 - +10V)
  • Ion Pump Controllers
  • Ion Gauge Controllers

ANY NON-STANDARD EQUIPMENT OR ADDITIONAL PIECES OF STANDARD EQUIPMENT IN EXCESS OF THE QUANTITY LISTED MUST BE REQUESTED IN ADVANCE.

SSRL has a UHV chamber with a double pass CMA spectrometer available to users. (Contact Roger Carr, ext. 3965) for specific information about this system. REQUESTS FOR THIS CHAMBER MUST BE INCLUDED ON THE BEAM TIME REQUEST FORM.

Vacuum Pump Shop

The vacuum pump shop is staffed by Ken Culler (ext. 2099). The following equipment is available for users, but must be requested in advance on your User Support Requirements Form.

  • (4) Turbo Pump Carts
  • (16) Roughing Pumps

There are not always enough turbo pumps to go around, so you should indicate if you can use a diffusion or ion pump cart instead.
