Revision as of 10:16, 29 September 2020 by Kent Paschke (Created page with "Back to Main Page >> HRS_Optics_Mtg previous meeting << >> following meeting == Logistic information ==...")
Time: 12:30-1:30 Toll-Free Number (U.S.& Canada): 888-240-2560 PARTICIPANT CODE: #543 006 042 Room IRL: <none> https://bluejeans.com/543006042
- Optics and Pointing
- Optics database. (Hanjie available to help with cross-checks?) We need to get this in our hands so we can analyze Q2 data from over the run.
- Pointing (Siyu) We need to get to final precision
- G4HRS and energy loss
- Estimate of ionization energy (constant) offset (Hanjie)
- Ionization straggling. This may require an improved vertex handling. Defered to post Oct 3.
- Acceptance function
- Build C-Pb-C sandwich targets in G4HRS. (Hanjie? Ryan? Cip?)
- Detector position sensitivity to analyzing power ("apparent" acceptance function from data) (Devi, Bob, Kent )
- Sensitivity study for acceptance function Q1 collimator cuts, or polar angle dist. (Devi, Bob, Kent )
- Verify sieve hole acceptance in septum scan (Ryan, Kent)
- Verify scattering angle correspondence MC vs data, perhaps central sieve hole? (Kent, Ryan)
- Vertex correction (Ryan, Kent)
- Carbon Background (Cip, Weibin)
- Carbon/Lead target thickness.
- Cross-check Carbon background. (Cip, Weibin)
- Simulate Carbon acceptance with radiative tail
- Separate Carbon/Pb distributions from sandwich targets
- Compare C12 acceptance to C12 distribution from Pb targets, for Q2 comparison.
- Calculate average carbon contamination fraction, and kinematics (for correction)
- Q2 data set (Hanjie, Chandan)
- Q2/Acceptance function, multiple measurements. Run with new optics DB, compile results (Hanjie)
- Consider possible carbon thickness variation or acceptance function variation as a function of target lifetime (Chandan)
Please post slides in haplog or docdb, before the meeting
- Proposed next meeting: tomorrow at 3:30.
