X-Ray Setup

 

At our institute we have an X-ray setup equipped with a 2000W tungsten tube up to 60kV.

Here are the main parameters:

 Accelerating Voltage 20-60 kV
 Electron Current  2mA - 33mA (Pmax=2kW)
 Beam Spot Diameter  1-2cm
 Dose Rate  ~7kGy/h (V filter, spot size ~14mm)
(depends on distance and filter)

This source is ideal to generate surface damage in electronic devices. All covers should be removed since the half range of 35keV (MPV @ 60kV) gammas is about 4mm (see NIST). Positioning of your device is assisted by a laser alignment system. Lemo and banana plugs for electrical connections are preferred. A software interface helps you planning the irradiation and controlling the X-ray tube.
