Agenda:

1- New "5 MeV" Dipole update and shielding of Earth's magnetic field

2- Bubble Chamber progress at Argonne

3- January 12, 2014: achieved p=9.1 MeV/c or K.E.=8.6 MeV for one hour. Still, suffered from trips due to wave guide vacuum faults; may improve with more processing.

4- Issues raised during Accelerator Seminar on Jan 23, 2014:

- To better control bubble chamber deadtime, do we want to stop the beam when the bubble chamber is not ready for next-event?
That is, beam is on only when chamber is in superheat. We can do that by blocking the laser path.
- Is there a nuclear reaction that would help us with the energy measurement?
- Can we present a theoretical calculation that shows the impact of JLab projected data on the the knowledge of S(300)?
