We will meet in TED 2561B on Wednesday October 23 at 3:00 pm EST.
For those calling in we'll use the ReadyTalk audio conference system.

Agenda:
1- Progress at JLab:
- Chris Tennant will develop an ELEGANT model of the beamline and help characterize the beam coming out of the 1/4 cryo unit - Shaun Gregory started the design work for the experiment - Jay Benesch is designing a new dipole to achieve the requirements on absolute beam energy - George Kharashvili will help with the electron dump design and FLUKA simulation
2- A new "5 MeV" Dipole media:new_5Mev_dipole.pdf media:new_5Mev_dipole.doc
3- Planned beam studies this Fall:
- Measure beam energy in the 5D line (Bubble Chamber mini-beamline) - Measure beam properties coming out of the 1/4 cryo unit - Increase gradient of 1/4 cryo unit to achieve 8.5 MeV kinetic energy in the Injector. During PEPPo, achieved 8.25 MeV/c, or 7.75 MeV kinetic energy - Measure radiation levels (gamma and neutron) vs beam energy and search for any activation - Measure beam current with BCM0L02 and find error on the charge over the range from 1 nA to 100 uA
4- Dead time systematic error
5- Bubble Chamber progress at Argonne
