Summary

• finished closing the hall about 4 pm
• set spectrometers to CAFE kinematics
• checked beam with harp scans and hole target
• checked and adjusted coincidence trigger with LH2 target
• took carbon "mean field" data
• ~10: 30 am moved to gold target

Current Status

• target is cooling down; expected to have condensed targets by Tuesday afternoon
• reeastablished coincidence trigger for CAFE
• HMS spectrometer rotation being done right now; Solid "bunker" already relocated; moving HMS to 30 deg and then relocate solid detector
• earlier CAFE folks had a meeting to settle on their runplan.

Current Run Plan

• Once we get beam back, run two days for CAFE
• then start deuteron experiment

Issues/updates

• LH2 loop has a problematic fan motor controller; dumps too much power into target; current limited to ~ 20 uA; probably need to warm up LH2 before accepting 40 uA on LD2

Planned Accesses to the Hall

• none planned; will the LH2 warmup require an access?
