temperature of chiller set to 15°C
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 |

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 |
