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).
The Bayard-Alpert Sensor in the chamber has to be deactivated, otherwise the light emission will increase the noise on the DSSSD strongly and reduce its performance.

Additionally the current and voltage from the CAEN HV is monitored with the vulom scalers: ch.13(Icool) = current; ch.14(Ucool) = voltage.

  285   Fri Nov 20 15:53:37 2020 JanAnalysisTest of 2nd DSSSD (gen2)2021
Here is the analysis of the test runs with the 2nd DSSD (gen2) using the quick_si_plots.c script attached.

All 32 Si channels are working with acceptable performance. 

In run001, there are some additional low energy peaks in nearly all x-strips, which I do not understand yet. They are around 3 MeV and are not visible in the y-strips. It doesn't look like an electronic problem, because there are at least 4 
peaks, so not a low amplitude copy of the 3 major alpha peaks between 5 - 5.8 MeV.

However, in run002, the peaks have mostly disappeared, only in x6,x7,x8,x9 is a broad structure at somewhat similar energy... maybe this has to do with the small incident angle of the alphas?

Another run to confirm and double check this would be nice.

During the detector test test measurements with alpha source the allocation of the 16 X- and 16 Y-channels has been checked.

For the following final allocation, it is always assumed that the (horizontal) y-strips are placed to face the beam directly, while the (vertical) x-strips are on the backside.

Now, all cables from the preamp to the ADC/TDCs are either labeled BLACK (= X-strips, pos. signals) or labeled RED (= Y-strips, neg. signals). These red or black connections should be kept consistently in order to ensure a well known orientation of the DSSD during the experiment. The test run Si2_run006.lmd was taken with this final assignment and serves as reference.

BLACK LABEL > X1 to X16 > pos. MSCF > ADC/TDC ch 0-15 > 50 Ohm resistor at preamps HV-input
RED LABEL > Y1 to Y16 > neg. MSCF > ADC/TDC ch 16-31 > neg. bias voltage at preamps HV-input

Additionally, the RED label indicates the section on the preamp to which negative bias voltage should be applied.
  287   Tue Feb 2 13:59:00 2021 JanDetectorsDSSD installation and alignment2021
The DSSD has been exchanged and aligned in 
November 2020. After bakeout at 140°C 
(externally, 120°C at internal temp. Sensor) 
for more than a week, the vacuum in the setup 
is roughly 4.5e-10 mbar.

After the bakeout the detector had to be 
realigned, it was lower by 1-2 mm. Using the 
line laser the realignment was done by 
touching only the screws on the far part of 
the base of the flange. These screws have been 
thightend by about a 1/4 turn after releasing 
the headless positioning screw accordingly.
  288   Wed Mar 31 13:52:04 2021 JanDetectorsBaF Na22 Testing2021
On 30. and 31.03.2021 we did some testing with the 6 BaF detectors.

Trigger & threshold:
With a threshold at ~250 keV, each detector has an trigger rate of about 0.5kHz due to internal activity.

Energy spectra
All detectors showed the Na22 lines (511 + 1275 keV) and also the lines from internal activity.
The energy resolution was on the order of 8.5 - 11 keV, depending on the detector.

Time spectra
Raw TDC spectra showed self-stop peak.
TDC diff spectra (between detectors) show one main (sharp) correlation peak about 8ns = 30ch*0.293ns/ch off the zero. 
At very low intensity a time structure around this peak is visible in a region of 120ns around the main peak. This is not understood, the energy spectra look similar for all these time regions (above/on/below the main peak).
Additionally, the coincidence E-specta between detector 1 and 2 (gating on the main time peak), nicely showed only the 511 keV line from Na22 and some gras.

Overnight test run:
Det. 1, 2, 3, 4 with the Na22 source

This is the lookup table for the distance of each x-ray detector to the target.
See attached foto for explanation.

It is the same values as in 2020: https://elog.gsi.de/esr/E127/36

Detector A (dA) [mm] B (dB) [mm] C (dC) [mm] calculate result [mm]
35° 136.0 (1.0) 20.0 (0.2) 450.0 (0.5) C + B - A 334.0 (?)
90° 76.0 (0.5) 20.0 (0.2) 447.0/2 = 223.5 (1.0) C + B - A 167.5 (?)
145° 165.0 (1.0) 20.0 (0.2) 450.0 (0.5) C + B - A 305.0 (?)

Errors are estimated after measurement, final errorbars have to be double checked!

Still rate peaks, probably the ESR kicker or some other external influence. 
So we have double triggers occasionally. This might slightly affect deadtime determination.
  297   Fri Apr 30 10:55:34 2021 Jan GloriusDAQXray multi-triggers - blocking gate2021
From the CFD of Xray1 (90deg) we get multiple trigger signals every ~5sec for unknown reasons. 
No hint from the preamp signals.

The solution now is to have an extended blocking gate active in the trlo-config of node 2.
There is now a trigger_stretch of 2500ns for all Xray triggers:

trig_stretch(1)  = 2500ns;
trig_stretch(2)  = 2500ns;
trig_stretch(3)  = 2500ns;

This prevents the multiple triggers to reach the lmu (before_dt scalers)
However, this will also lead to a very small loss of good signal triggers that overlay within 2.5 us.

This has to be taken into account for deadtime determination.
