  98   Sat Nov 22 17:00:43 2014 Axel KönigInfineonInfineon olddamaged strixel sensors, strange IV behaviour   Unknown

1.) No events recorded for strixel sensors (run001). They seem to be damaged like they were at DESY.

2.) Very strange IV behaviour for every old Infineon module (especially TB12_baby1).

Saturday evening, the cooling became unstable which indicates the end of the CO2 supply, possibly having a mixture of liquid and gas phases.

Strange oscillations observed for the DUT temperatures until the MF valve was finally turned off close to midnight.

Der zweite PM (entsprechend der Beamrichtung) war von Anfang an nicht angeschlossen an die TLU! Stattdessen war ein Atlas pixel sensor, welcher als 4ter PM fungiert angeschlossen. Genau dieser "PM" hatte 0 counts bei der TLU --> Igor sagt, dass dieser Sensor ("PM") anscheinend keine Versorgungsspannung hatte (~400V). Jetzt baut Igor diesen Atlas Sensor wieder aus und hat bereits den nicht angeschlossenen PM wieder angeschlossen an die TLU. DIeser PM zeigt aber nun zu viele counts. Deshalb behalten wir die AND mask 11 (auch jetzt bei den Belle Modulen).
