Simulation Task List Updated 2019

Agenda

look closely at the residual source of photons from the upstream collimator regions to see if they can be further reduced
replace the outer kryptonite shield with the properly tuned lintels and 3 downstream collars
review the current status of the beam dump background and its impact on the detector plane region
construct the geometry of the detector PMT shielding, combine with backgrounds coming from the light guide and quartz tiles, and evaluate the final background levels at the main detector PMTs

Radial plots at detector area from Moller, ep and beam generator
Rates for Moller, ep, and photons from beam generator (E<10, 10<E<100, E<100)
2D scatter plots at detector area from Moller, ep and beam generator
2D Raster pattern at the upstream end of the target using Moller, ep and beam generator
2D Raster pattern at the entrance to the beam dump using Moller, ep and beam generator

Attendance: Rakitha, KK, Wouter, Ciprian, Sakib, Micheal, Cameron, Catherine,

Default design in Sakib's table first row for beam pipe includes tungsten beam pipe shielding that we had for past geometry design
Al-window and beam pipe is the dominant source of bkg.
Optimizing to reduce the photon background in the ee ring
- Breaking down the electron sources in e-ring coming from the Al windows and then Al beam pipes
Attach the slides that Sakib showed in the meeting
Sakib will import his geometry into the develop branch and make sure his magnetic field and develop branch field maps are same.
- Tag the git version that will be used for the CDR
