Target density variation check
From PREX Wiki
Jump to navigationJump to search- First measurement 09/02/2019
- HALOG summary
- Target #7 and #10 were checked for current range 5-70uA
- Septum mistuned on purpose in order to reduce rates, T2 trigger is used
- Sieve in
- Clear non-uniformity observed from degraded target (#10) compared to good (still in use) target (#7).
- More visible at higher current, but hint of similar signature of density rearrangement seen at low current.
- Consistent results from both LHRS and RHRS spot data
- Second measurement 09/03/2019
- HALOG summary
- Took high statistics run at very low current (30nA requested), Target #10
- Septum at nominal setting, no Sieve
- Similar result shown in RHRS data as previous high current test
- Different distribution in LHRS is puzzling
