Meeting 1 November 2019

DISCUSSION MATERIAL

• CPS FLUKA Comparison

ACTION ITEMS:

• (David H., Sean, Rolf, Donal, Tanja, ...) Finalize CPS article - target for submission: 22 November

• implement comments from Sean and Donal
• check figure captions
• add more detail on Hall D - Sean will send some text
• author list

• (Gabriel) Simulations in preparation for NSF MRI

• need radiation analysis on coil to determine what isolation material to use - for specific simulation specs see item 4a from 10/11 meeting (need one z-value)
• need some phi angles to see how much shielding to use - also item 4a

• (David H., Tanja) Funding proposal

• prepare an itemized budget for discussion
• prepare 1-2 page on CPS for David H funding proposal submission

• CPS collaboration meeting - determine date based on NPS agenda

DETAILS OF THE DISCUSSION

• CPS simulation update - step 0 is complete!

• Comparison of Parker Reid to Gabriel Niculescu simulations - they are consistent
• details of the simulations:

• both based on cylindrical geometry
• horizontal axis is the beam direction
• vertical axis is transverse to beam direction AND integrated over all phi angles

• should still figure out what the events in the indicated box are - strange since no material there

• Discussion about next steps for simulation

• Insert intermediate steps before step 1 to determine material needed for CPS and cost estimate for funding proposal

• complete step 4a for one z-value, factor 3 sufficient - choice of material
• need phi angles bins - amount of shielding, radiation going into floor etc.

• step 1 involves comparison to an Hall C experiment, e.g. J/Psi, to verify activation after 1000 hours running etc.

• Discussion about beam size in Hall D

• 10% radiator - take half the size (5%) and assume 11-12 GeV in Hall D - results in 2.5cm RMS after 80m

• Discussion about CPS article

• Comments from Donal coming
• David H. will implement comments from Sean, Donal, and check figure captions
• Additional authors - Sean will check with Justin on authorship

• Add some text on Hall D

• Try to submit by 11/22

• Discussion about funding proposal

• budget elementary: magnet and diagnostics
• require estimate for simulation step 4a, e.g., some phi values to see how much shielding to use and for radiation analysis of magnet coils and iteration with vendor
• assume JLab provides: support structure, cooling, safety for high radiation, beam line and beam line diagnostics
• David H. preparing UK funding proposal - include 1-2 pages on CPS; due date is end of November

• CPS collaboration meeting - plan for 3 February or 4 February 2020

• need to check agenda for NPS collaboration meeting (3 Feb 2020)
• no obvious conflicts for either day

NEXT CPS PHONE MEETINGS:

• FRIDAY 15 NOVEMBER AT 11:00AM (ET)
• FRIDAY 22 NOVEMBER AT 11:00AM (ET)
