== Radiation Benchmarking ==
 
* ERR recommendation
 
* Contact Dave Hamlette, Javier Gomez to discuss metrics for benchmark
 
 
 
 
== Design and Simulation ==
 
===Base design, v3 Benchmarks.===
 
<<Complete by March 16>>
 
* Need new benchmarks (accounting for updated geometry (dump, HRS) and SAMS
 
** for PREX-I, HAPPEX-II, PREX-2, CREX (and others?)
 
** on HRS detectors, under HRS detectors, Hall Lid or Hall Wall total ("whole hall"), and Hall Lid skyshine estimates
 
* prex2-v3:
 
** prex-2 dump, with shield
 
** no SAMS, or alternative SAMs?
 
*crex2-v3:
 
** (same with 48Ca target and 2.1 GeV)
 
* prex1-"??name??"
 
** PREX-I collimator
 
** PREX-I chamber? (not as important)
 
** PREX-I dump (with KW correction)
 
** no HDPE, no SkyshineShield
 
** Full size HRS det and structure, match prex2
 
** FULL PREX-I SAMS
 
* HAPPEX-II - ??name??
 
** HAPPEX-II collimator (same as PREX-I?)
 
** PREX-I dump (with KW correction)
 
** 3.2 GeV, 20cm LH2
 
** PREX-I chamber (not as important)
 
** no HDPE, no SkyshineShield
 
** Full size HRS det and strucutre, match prex2 sim
 
** FULL PREX-I SAMS
 
* PV-DIS?
 
* HAPPEX-3?
 
* TRITIUM (11 GeV)?
 
* DVCS?
 
 
===Geometry, Next iteration.===
 
<<Complete by April 6>>.
 
* realistic gaps around dump shield
 
* target chamber
 
* collimator chamber to match design
 
* HDPE around target to match design
 
* modified SAM design?
 
 
===Magnetic Shielding===
 
* Evaluate B-field in Q1 beampipe with only one Q1 energized
 
* Evaluate the Tritium-Magnetic-shield design
 
* Evaluate mag shield additions for upstream/downstream septum beampipe
 
 
===O-Ring damage===
 
* Plots:
 
** E-weighted, electron only plots from beamline det an o-ring det
 
** tables to arrive at integrated grays
 
**hall-lid det x0/y0 plot to show enhancement from full SAMS
 
* get info on O-ring from engineering. (material, lifetime expectations, also when did this appear?)
 
* Full base design (Feb18), but w/o dump shield
 
** Use Al around O-ring
 
*** No SAMS
 
*** PREX-I SAMS
 
** test 1/2 size O-ring (PREX)  (PREX-I SAMS)
 
*** Done, but dumb results.  Compare 1/2 size O-ring with 1/2 of full size O-ring.
 
** test no material around O-ring (PREX) (PREX-I SAMS)
 
** CREX
 
*** No SAMS
 
*** PREX-I SAMS
 
** check beam-offset run
 
* Results for alternative SAM configs
 
* Final estimate use full base design (Feb18), including dump shield
 
** PREX-2
 
** CREX
 
 
===SAM redesign===
 
* calculate rates vs angle
 
* calculate doses vs angles
 
* get details on beer can, make default design including welding
 
* Attempt final design
 
* Propose/Exam alternative SBMs
 
 
===Activation Estimation===
 
* Downstream septum beampipe flange, contact dose
 
* Downstream septum beampipe flange, whole body dose
 
* CREX activation estimates
 
* HDPE activation.
 
* DUST ACTIVATION?
 
 
===HDPE parameters===
 
* Total / peak radiation dose. Damage?
 
* spec non-flamable HDPE, or devise fireproofing
 
 
===Thermal Neutrons:===
 
* count thermal/near thermal (<1eV rate), assume 8MeV / n energy release, compare to E&M power 
 
* plot sources of thermal neutrons in hall, using hall-lid and HRS-platform detectors
 
* consider effect of 5% boron 
 
* calculate thermal neutrons at Compton polarimeter
 
 
=== Polarimeter doses ===
 
* Evaluate dose and neutron rates (both thermal and above) at Moller and Compton locations
 
** Moller target holder uses o-ring (evaluate dose)
 
 
=== Spectrometer Optics Design ===
 
* FOM optimization
 
* Q1 collimator cut-out
 
 
== Analysis Chain ==
 
* First attempt at new analyzer <<June deadline>>
 
* Test on PREX1 data.
 
** (Re)Create plots that were used to verify PREX1 data integrity/quality
 
** Add analysis and drawing macros to analyzer package
 
* Create fake PREX2/CREX data with updated names and addresses for BCMs, BPMs.
