|
The new detector holder incorporates a Pt100 temperature sensor, which is UHV compatible. The Pt-resistor is read out via 4 wires. These wires are integrated
into the D-SUB connector of the detector. The new wires use the pins as shown in the attached picture
"det_connector.png".

Thu Aug 29 10:02:22 2019, Jan, Detectors, bakeout at ESR setup,
|
The bakeout for our detector setup has started on the evening of 27.08.2019
We have a temperature sensor in the vacuum next to the detector.
The goal is to maximize bakeout temperature, while not going above 125°C at the detector/sensor.

Tue Mar 10 09:41:26 2020, Jan, Detectors, x-ray background from BaF,
|
The BaF2 detectors planned to be installed at the target induce an additional background in the x-ray detectors sitting below inside the target chamber.
We made test measurements with an x-ray detector for estimating the background in the region of interest for our K-REC measurements (35 to 50 keV).
