- OSP docs and writing assignments - all
- Note: MUST get everything to committee immediately to get OSP by 18-Oct!!!
- writing assignments
- will need RadCon survey, may need TLD to work on platform
- Addition of Hall probe and fast readout correlated with magnet current
- to detect turn-to-turn shorts
- needs rigid mount, but no personnel access to magnet bore when cold
- Pager for coil test on-call person
- n.b. we previously decided on a hand-off strategy
- the new ones are free!
