Accelerator Physics meeting minutes
10/10/2001


Present: J. Wei, J Galambos,M. Doleans, S. Danilov, S. Aleksandrov, 
 E. Tanke, S. Kim, D.Jeon, J. Holmes, P. Chu

J. Wei showed the new ASD organizational chart highlighting the new commissioning 
areas with Sasha Aleksandrov, E. Tanke and S. Henderson with lead roles of responsibility.
The proposed DOE talks were reviewed, and a new ASD approval process for procurements
(requiring accelerator physics approval signatures) was reviewed.

There was a discussion on the status of the discrepancy between the LBNL and LANL 
calculated beam distributions coming out of the MEBT. There is no apperent resolution
yet (LANL calculates broader tails). This will be pursued at the upcoming commissioning
video. 

There was a discussion on the LOrentz detuning issue, and JLabs consideration of using piezo electric comensatio. Kim explained the alternate adjustable capacitive solution, using fast
phase shifters. This will be discussed at the upcoming video with JLab.

The critical correctors that can cause damage if not operational (and hence
machine protected) need to be identified. Y. Pappaphiloppu is looking at the Ring, 
D. Raparia is looking at the transfer lines, and D. Jeon will look at the linac. 
There is a question as to how many full pulses the device can take as a function
of energy (Shafer's note on this issue will be looked at).

The parameter list needs editing, and will be looked at by everyone, with Wei and
 Galambos collecting the changes. The front table will be reformulated to 
more easily communicate emittance and ecceptnace throughout the machine.

A "holy lattice" will be constructed for the entire machine, and will include all 
the diagnostics, correctors, and other beamline devices such as RF, collimators, targets
etc.
