Standing Agenda

Blocky locations for DS conductors has been provided to use in Tosca
- Not expected to having any significant impact (3 mm adjustment) but model should reflect current design specs
Finalized design for sieve, blocker, and collimator 1 &2 (and 2 bounce) needs to be finalized
JM is working e+ energy deposition in W and Pb for side plate dose investigation
KP is performing sims of lintel locations (Prakash - postdoc)
MIT finalizing design drawings
MD working 3A items (schedule, procurements, etc.), cooling water activation

Return to Spectrometer Meetings
Return to MOLLER Wiki Main Page

Attendance: Juliette, Ernie, Cip, Jason, Dave, Jim K., Jim F., Kent, Sakib, Tricia, Danielle, Vladimir, Mike

++NEW++ required - lollipop for shielding the target
- HW for calculations
- required from last OPA review
New conductor config for symmetric conductor; working on the asymmetric configs
Sieve waiting for additional holes from optics
have radDamage code and making the model
KP is performing sims of lintel locations (Prakash - postdoc)
MIT finalizing design drawings
- need drawings free from proprietary info (Plansee is being paid for engineering - did sign an NDA)
- what is covered by NDA?
MD working 3A items
- scheduling and procurements for all 3a items
- cooling water activation - resin filter in main LCW (inventory of all items)
  - lintels - 7 W each? want to be able to cooled with the LCW and NOT the chiller (high compared to coils?)
Sakib and W vs. Pb
- changes in upstream region; 2-bounce thicker and gap ignored for now; collar-0 outside of shielding, etc.
- need to add gap, remove nose shield
- Pb, W ~ 80 MGy vs. 70 MGy
Kent and ferrous materials
- Brass 485 had a low measured susceptibility
