Belle stack w/o Origami2 after irradiation
HV=80V / 258 µA
cooling: Origami only, chiller set to -25°C,
2 suspicious APVs on n side of Micron due to burnt strip
Bias connection of Origami repaired --> lower noise on 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 |

Belle stack w/o Origami2 after irradiation
HV=80V / 255 µA
cooling: Origami only, chiller set to -25°C,
2 suspicious APVs on n side of Micron due to burnt strip
same position as in previous run
telescope run 20197 - wrong config file @ telescope -> new run with correct settings |

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) |

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... |
