So steuert man einen Testbeam!

Dieser Stack wird jetzt quasi als Pausenkasperl eingebaut und läuft im "stealth parasitic" mode während der Irradiation-Woche. Gut, dass wir alles auch von Wien aus fernsteuern können :-)

Internal calibration for "stealth parasitic" mode Belle stack; taken without beam

 

Belle Stack 4: 2 DSSD -z, Origami #3, #1, wedge new #2
HV = +-50V, Ibias=80A
Position: approx. centered
no beam
 

 

Total bias current history:

currents.png

At the beginning, the system was already running for a few hours and the APV25 chips were initialized before, so thermal equilibrium was reached.

The actual calibration run happened during the first ~250 measurement points (~1 hour). It seems like the APVs draw a bit more current during internal calibration. The overall decay is supposedly due to a temperature decrease towards night.

 

Now tried the same thing with a short software run - same effect:

currents2.png

Need to investigate supply currents while data taking - they should actually go up a bit - and their dependency on the trigger rate.

Belle Stack 4: 2 DSSD -z, Origami #3, #1, wedge new #2
HV = +-50V, Ibias=77A
Position: APVs #2, 7, 11, 15 | # 17/18, 21, 25, 29
= p: 2DSSD #2, Origami3 #3, Origami1 #3, wedgenew #3
= n: 2DSSD #1/2, Origami3 #1, Origami1 #1, wedgenew #1

 

Stack is now positioned on globally best performing position which should also enable reasonable tracking.

Trigger timing not perfect, needs adjustment (-1 CLK) -> new run

Same as run016, but timing shifted by 1 CLK to better center the peak of the shaped wafeforms for subsequent fitting during analysis.

 

Beam was turned off around here:

19.10.2012  08:56:12  event=193394

So better ignore the last ~5000 events for analysis.

beam went off (LINAC problem) around

Beam shape on n side (horizontally) different than in previous runs. Number of triggers per spill is reduced to ~60k (was 200..250k before). Reason unknown.
