We will meet in TL 2236 on Wednesday February 12 at 3:00 pm EST.
For those calling in we'll use the ReadyTalk audio conference system.

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 at the operational pressure. 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)?
