  • 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
