Origami1 (n-side only) + Micron1 (non-irrad)
angle scan: 73 - now with multi6 (previous run was single)
HV=100V / 35uA (beginning of run) 34uA (end of run)
cooling: chiller set to 15C

telescope run 20201

Origami1 (n-side only) + Micron1 (non-irrad)

angle scan: 73 degree

HV=100V / 36 uA  (beginning), 35uA (end of run)

cooling: chiller set to 15C

 PROBLEM: wrong config file (single hit, not multi6)

telescope run 20200

Origami1 (n-side only) + Micron1 (non-irrad)
angle scan: 73°
HV=100V / 40 µA
cooling: chiller set to 15°C

Origami p-side does not receive triggers -> disabled

origami flex straight part needed to be folded due to severe rotation angle -> nanonics connector problem...

Belle stack w/o Origami2 after irradiation
HV=80V / I_start=255 µA, I_stop=243 µA  

cooling: Origami only, chiller set to -25°C,
2 suspicious APVs on n side of Micron (possibly due to burnt strip)

same position as in previous run

telescope run 20198 - now with correct telescope threshold settings

a lot of "Error detected in APV 21, subevent 2. Event discarded, reset sent." errors started at 09.10.2010 09:00:25 (after whole night without any error)

telescope run 20197  - wrong config file @ telescope -> new run with correct settings

17deg acceptance => Schnittwinkel barrel option = 90-17 = 73deg      ----->  rotary table 80.5

layer zusätzlich slanted um Winkel alpha => Schnittwinkel = 73 - alpha

slant angles: layer 4: 11.9deg => Schnittwinkel 61.1deg       ----->  rotary table 68.6
                     layer 5: 17.2deg => Schnittwinkel 55.8deg       ----->  rotary table 63.3
                     layer 6: 21.1deg => Schnittwinkel 51.9deg       ----->  rotary table 59.4

Im Vergleich mit senkrechtem Durchgang der Teilchen erwarte ich eine Vergrößerung der cluster width um den Faktor tan(Schnittwinkel):

slant layer 4: 1.81
slant layer 5: 1.47
slant layer 6: 1.28
barrel:           3.27

Bias connection of Origami repaired --> lower noise on p-side

2 suspicious APVs on n side of Micron due to burnt strip

trying to identify problematic Micron n side channels with low bias voltage (APV22 baseline saturates at higher bias)

Belle stack without Origami2
HV=80V I=217uA

beam stopped at 7.10. 08:00 sharp, no beam until 8.10 - 8:00 according to SPS Page 1. We keep DAQ and telescope running and cross our fingers for at least some spills of particles.

Irradiated micron module 2, n-side: excessive hit count on channels at the edges of the APV chips - no such thing on the p-side
