Target Meeting (Hypernuclear experiment at JLab)
- 23:00-24:00 on Oct 29th, 2023 EDT (12:00-13:00 on Oct 30th, 2023 JST)
- Participants: David Meekins (JLab), Toshiyuki Gogami (Kyoto Univ.)
- via ZoomGov

Target list (only solid targets for the next run)
Approved
- E12-15-008: 40Ca, 48Ca (150 mg/cm2)
- 40 is easy to obtain, but not for 48.
- Dave asked Oak Ridge National Lab. to purchase the Ca material.
→ no response yet.
→ Dave will contact the Lab.
- E12-20-013: 208Pb (100-150 mg/cm2)
- The thickness needs to be fixed for design.
- Cryogenic system would be needed for cooling.
- 20 μA would be OK to apply.
- Common calibration: 12C (150 mg/cm2), CH2 (500 mg/cm2), 27Al (150 mg/cm2)
Proposing next year
- LOI12-23-013: 6Li, 9Be, 11Be (100 mg/cm2)
- LOI12-23-016: 27Al (100 mg/cm2)
- LOI12-23-011: there may need special needs.
Some comments
- Solid targets are planned to be used for the next run.
But, the target system would be better to be compatible with gas targets (E12-19-002). - ERR, for example, in Mar is possible for the (solid) target part.
- Requirements for the target (position accuracy etc.) need to be summarized.
- Let's keep using MS Sharepoint for sharing information and documents.
Next Meeting
13:00 p.m.- on Nov 14, 2022 (EDT) at JLab.
