Meeting 22 January 2019

ACTION ITEMS

• Preliminary Proposal

• Project description: Dustin will send a writeup on Oxford work - fold in the description
• Budget updates: Igor will send info on tungsten (see his email from 1/22/19), Dustin will send numbers for target based on Oxford experience
• Science figures: Gabriel will try to optimize figures, e.g. for RCS try a multi-panel figure that illustrates that with CPS can take data in a region where theoretical uncertainty is large. For TCS need to project why CFF is important and why one needs these four components. Dustin will write a paragraph on this.
• PEP: aim for 1-2 sentences to address each point in the list, meet during Hall A/C meeting to go over details
• Bio sketches: Gabriel will send a helpful script for extracting collaborator info from databases

• Article

• Take David's cleaned up tech document and see what sections to port to the article

Discussion Details

• Discussion prelim proposal/article draft sections

• FOM figure contains only polarized target data, includes 2008 Mainz point from Igor, note that HIGS and SOLID are the same bar

• Budget estimate

• Target estimate based on C. Keith's estimate, aims to have largest possible opening (new), recycle existing equipment, but replace aging pumps, separate magnets for longitudinal and transverse configurations
• Dustin has a writeup from Oxford on cryogen-free solution, transversely polarized magnet, can rotate sideways and vertically, traditional design with smaller apertures
• for tungsten figure used $3.5M here
• tungsten inserts updates figure (1/22/19) is $122k
• Target numbers - include Dustin's numbers based on Oxford
• Tungsten powder - see Igor's email update

• Science figures: RCS and TCS

• RCS

• in general good to show more points do demonstrate that can do more with CPS and gives credence to FOM
• need to optimize to illustrate how much more range and how difficult the measurement is
• Possible improvement: make multi-panel figure, e.g. for low and high t

• TCS

• make unique piece jump out more
• in general, why are CFF important and why do we need these four components - goes back to EM and electron scattering from a moving quark
• make connection to: with new CPS technique can measure very small cross sections in this new era and now can do real electron scattering from moving quark

• PEP

• template with principles that regular DOE projects have
• scope similar to SBS, DIRC, etc. - projects at JLab
• aim to explain in 1-2 sentences for each point what will be done
• budget profile - use budget and required time for each piece

• Discussion Article Draft

• David H sent updated version
• Use the cleaned up version and see what sections to port into/merge with the section drafts
• aim for more discussion at 1 February collaboration meeting
