Present: M.D., A.D., S.Š, J.S.,

General:

• On 09/08/2020, we had a meeting with C. Keith re. target.
  • Timeline? Will determine when we can say we are ready to run.
  • CK reminded us that the $600k quoted in the proposal is if we re-use parts from the Hall B FROST target. (Without them, the cost would be about $3M.) AD asked if it was a sure we could re-use these parts or if Hall B may want to reclaim them at some point, and CK. confirmed the part where unconditionally available. This is because the core of the target has a superfluid leak that the target group was never able to identify, so this target is not easily available to Hall B in any case. Related to this, MD asked if re-using the Hall B target was still an option. CK said yes, but refurbishing it will take about a year of full work, and he prefers to built a new target better adapted to Hall D and improved by his experience on building and operating the Hall B target.
  • Where do the funds come from? Most likely JLab capital equipment.
  • Manpower: target group.

S.Š:

J.S.: Also, FYI from Eugene’s slides at the last CM https://halldweb.jlab.org/DocDB/0044/004458/001/talk_coll_2020_may.pdf he indicated that the FCAL-II insert was a 3 year CE project that started in FY19. With contingency, that probably means they’ll finish spending $$ in FY22. This aligns pretty well with Chris’s projected need for funds in FY22/23 for the beginning of target purchasing. Note: it’s challenging for CE funds to support 2 major projects simultaneously (e.g. DIRC finished before FCAL-II began), so we would be competing with other things projects like KLF, TRD, etc. after FCAL-II. After our meeting tomorrow it would be good to arrange a meeting with Eugene to discuss these scenarios.
