WE ARE LOOKING FOR 1-2 STUDENTS OF PHYSICISTS INTERESTED IN JOINING US. Tasks: simulations and data analysis.
Second test period (P2) 25-28 January 2019 with the left Mott polarimeter and narrow collimators – a proof of a clear separation of the Moller events and the internal low-energy background
Third test/measurement period (P3) 9-15 July 2019 with the left Mott polarimeter and intermediate collimators; 119 runs recorded, data analysis in progress.Preliminary result for the Sherman function @ 2 MeV and 120 degrees from the measurement of beam asymmetry, in the range: 0.05 – 0.06. Two DRS4 modules used.
Fourth period (p4) forseen for January 2020. Change of detectors – PMT’s replaced with photodiodes (counter tests in October).
DRS4 modules intercalibrated (Warsaw).
Ongoing work: purchase of photodiodes, adapting scintillator housing and lightguides, tests of counters (Michał Drągowski+TUD team).
First test period (P1) 19-22 October 2018 with the left Mott polarimeter and wide collimators; study of internal and external background.
Tests of scintillation counters and data acquisition (DRS4 module) using a 90Sr radioactive source and cosmic muons.
