  • 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!
• Installation status - all
  • vapor-cooled lead connections
  • what's left?
  • when do we give two weeks notice to Errol?
