Description:
We have two pre-amplifiers:
New: Max. range 5GeV, Two sensitivity options: 1 GeV and 5 GeV, Decay time = 30 us, pulse input 220 MeV/u, Ser. #MPR-32-D-5000-30-1118380.
Old: Max. range 5GeV, Two sensitivity options: 1 GeV and 5 GeV, Decay time = 25 us, pulse input 220 MeV/u. Ser. #MPR-32-D-5000-25-0414310.
Conclusion:
Both pre-amplifiers work well.

Chen, Sidhu | Detectors | The thickness uncertainty of Ta is less than 1%. |
The thickness of Ta plate have been measured by target group. The result is show as following.
According to this measurement, the thickness uncertainty is less than 1%.
This thickness uncertainty is good enough for Tl experiment.
