Run summary
- 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, might be related to DAQ problem
- Qsq runs 09/03/2019
- 400-500k events for LHRS and RHRS runs during Qsq measurements with various targets (Pb7, 8, 9, 10)
- HALOG run summary
- Consistency between LHRS and RHRS recovered for target #10 [1]
How to make plots
- full replay macro can be found from:
/adaqfs/home/a-onl/sanghwa/stupid_spot/get_rastersize.C
- To run:
> analyzer -b -q 'get_rastersize.C(run#, first evt, last evt, "outputpath/outputname")'
Example:
> analyzer -b -q 'get_rastersize.C(2293, 1, -1, "rootfiles/L2293.root")'
- To draw raster current xy distribution:
- /adaqfs/home/a-onl/sanghwa/stupid_spot/make_2D.C
> root -b
> .L make_2D.C
> plot_all("dyn_therm.list")
This will create dyn_dens.pdf. To open:
> evince dyn_dens.pdf &
- Input file format:
<LHRS run#> <LHRS file path> <RHRS run#> <RHRS file path> <current> <target#>
