SLAC LARP Phase II Collimation-9/19/2005 (30)

9:00:00 AM-10:00:00 AM

 
Agenda: Review of progress:
Doyle: Change to energy absorbed by secondary when primary collimator length changed from 20cm to 60m
Summary: Outstanding action items:
-Post postdoc ad (Tom)
- Engineer search:
- Tor to contact FNAL to rekindle ideas for experienced personel
- Eric to re-contact Andy R. (DONE: no change, no interest)
- Tom to re-contact Gordon B. (Done: no interest)
- Eric to contact Stuart Metcalf (in progress)
Conceptual Design Report:
-Eric to finish first draft
-Lew/Tom to review & add appropriate appendices
ESB clean room:
Eric to contact MCR regarding interferance with MARX modulator
Eric to recreate list of needs to equip clean room
Other:
Tom to contact Yunhai that he make hit distribution for 60mc primaries and verify efficience for 75cm secondaries
Tom to contact Assmann regarding 60cm primary hit distribution and comments on RF shield scheme proposed by Eric at end of July. (DONE, but no reply yet)
FLUKA computer:
Lew to contact Fasso for specification of device.

1 .) id=90  Eric Doyle --  Heat load & deflection in Secondary Collimators when Primaries change from 20cm C to 60cm C  (5 min)

Summary: Heat load reduces from 15.8kW to 11.3 kW in steady state loss condition. Deflection reduces from 72.5um to 53um. In the 12min beam lifetime case power absorbed reduces from 79kW to 57kw and deflection from 752um to 520um.
