|
This is the documentation of the source tests with the 2nd micron DSSSD of 2nd generation (label 3288-17, thickness 529um)
The detector is put into vacuum (~5e-6 mbar) in our test chamber. The source is positioned a few cm above (see fotos).

From the CFD of Xray1 (90deg) we get multiple trigger signals every ~5sec for unknown reasons.
No hint from the preamp signals.
