Notes from this meeting:
- Superheated fluid will be C2F6
- Beam Energy Tasks:
- Analyse beam energies used during September 2015 Bubble Chamber Run I similar to what Grames did for Mott run.
- Measure the stray field in 5D line (Bubble Chamber) since new steel was added between 5D00 and 5D01 BPMs and to extend measurement to radiator.
- Use installed Hall Probe to study systematic error in beam energy measurement (0.01% accuracy, resolution to 2 ppm, and a temperature stability of 10 ppm/°C).
- Temporary Operational Safety Procedure (TOSP) expired on December 8, 2015. Needs new approval with updates on modifications: no mercury, new collimator, new lead camera shielding.
