Target Meeting (JLab Hypernuclear experiment at JLab Hall A/C)
- 21:00- on October 12th, 2021 EDT (10:00- on October 13, 2021 JST)
- Participants: David Meekins (JLab), Toshiyuki Gogami (Kyoto Univ.)
- via Zoom
Discussion
- To ERR
- We set a target to arrange ERR in October 2022.
- Basic information check / Discussion
- Gas target (3,4He, H2)
- H2 target cell needs to be a little bit larger that that of helium targets.
- Optics target (5 carbon foils)
- Solid targets
- Multi-target configuration for each target is being considered in the case of Hall A option.
→ The multi targets seems to be very difficult in the case of Hall C because of poor S/N. - Multi-target configuration seems to be difficult for Li, CH2, Ca.
- Multi-target configuration for each target is being considered in the case of Hall A option.
- Ladder
- horizontal insertion is much harder that vertical one.
→ Let's decide to consider only vertical option.
- horizontal insertion is much harder that vertical one.
- Gas target (3,4He, H2)
- Scattering chamber
→ new one that is dedicated for the present experiment is needed.
- Next work
- Dave is giving CREX/PREX target drawing to Toshi
We will start concrete design with this.
→ Toshi will work on 3D CAD drawings.
→ Toshi received the file on Oct 21, 2021.
- Dave is giving CREX/PREX target drawing to Toshi
Next Meeting
10:00 a.m.- on October 22, 2021 (JST).
(9:00 p.m.- on October 21, 2021 (EDT))
