The XR-100 can be operated in air or in vacuum down to 10-8 Torr. There are two ways the XR-100 can be operated in vacuum: 1) The entire XR-100 detector and preamplifier box can be placed inside the chamber. In order to avoid overheating and dissipate the 1 Watt of power needed to operate the XR-100, good heat conduction to the chamber walls should be provided by using the four mounting holes. An optional Model 9DVF 9-Pin D vacuum feedthrough connector on a Conflat is available to connect the XR-100 to the PX2 outside the vacuum chamber. 2) The XR-100 can be located outside the vacuum chamber to detect X-Rays inside the chamber through a standard Conflat compression O-ring port. Optional Model EXV9 (9 inch) vacuum detector extender is available for this application. See photograph of XR-100 with extender and Conflat.
The EXVC - Collimator Kit Includes Stainless steel collimator housing, Brass Spacer
