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 the 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

4- Dead time systematic error

5- Bubble Chamber progress at Argonne
