Present: M.D., A.D., S.Š, J.S.,
General:
- On 09/08/2020, we had a meeting with C. Keith re. target.
- Timeline:
- It will take about 3 years to build the target, assuming that project has high priority. Currently, the target group has many other target to build (Møller exp. target, Hall B pol. 3He target, back-up for HDice transverse target...) or refurbish (Halls A and C cryotargets).
- It is clear that the Møller target has the largest priority and it will consume CK time until 2023. Thus, the soonest we can think of running the experiment is 2026, and that's if we convince JLab management that the next high priority work after the Møller target is the HD FROST target.
- Assuming 2023 as the date for the start of the target work (and it's not a given), this is when we will start using whatever budget we secured to build the target. So we should aim for this date in the proposal grants.
- 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.

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.
