Preamplifiers

• Natalie performed more analysis on the VPTT preamps. Now the spread looks like the Bochum measurements. The relative numbers should be compared. The absolute value from these measurements is not known.
• Measurements of APD preamplifiers show much more similar behaviour in gain. They should be measured in Basel to a percent level, such that no more measurements in Bochum is needed.
• About 400 APD preamps are ready to be sent to Bochum, but there are administrative problems. About 40 preamps should be transported directly to Bochum.

Bonn

• Due to air conditioning pbs. currently no measurements are ongoing.
