Hi All,

We just had the meeting and went through the new task list after the review.
Please take a look and check your responsibilities.
Here is the summary:

1.the Qweak double-difference systematic estimate (go beyond crude
estimate presented by Kent on the second morning in closed session) for
both quartz and shower-max detectors

Kent and Ciprian will work on it after the detector geometry is finalized by
Dustin's group and KK's group

2.State of the art radiative corrections for both signal and background
processes to be incorporated (I thought we have this already?) Mainly to
update the simulation with the internal radiation

Postdoc level project, Seamus has some thoughts on it.

3.excess noise (I guess just background estimate for now) in detectors
after completing shielding design (in our plans)

Mainly scintillation/Cerenkov backgrounds, SBU group is working on it.

4.scattering of primary beam due to fringe fields in central beam pipe
from broken symmetries in toroid alignment

Juliette will work on it

5.radiation damage quantified in nose of hybrid coil to ensure epoxy will

Cameron and Juliette will work on it

6.consistent and actionable approach to sensitivity analysis for both
backgrounds and helicity correlated effects to specify manufacturing
tolerances on spectrometer

related to spectrometer, Juliette will work on it

7. mu+mu- pair production in target for both primary detectors and pion

Wouter's group is working on it

8.splash back from showermax detectors on main detectors

Bradly will work on it as his spring project

9.crosstalk due to showering in detector support structures
N/A, overall simulation with all the detectors in

10.Mott scattering in full MOLLER geometry (why has this been singled out?)
N/A, backgrounds study

11. optimize quartz detector segmentation to minimize systematic error due
to background subtraction

UVA group

12.backscattering from beam dump: impact on pion detectors and main detectors

Wouter and pion group

13. excess noise main detectors due to background from beam dump
N/A, backgrounds study

I will update these in our meeting page.
