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)

Entry  Fri Oct 8 23:22:32 2010, Manfred Valentan, BELLE, Schnittwinkel barrel vs. slanted, , , ,  

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

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)

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
