Measure magnetic field strength as function of current dB/dI.

Need to simulation on HRRL radiation. Place a cylindrical detector near corner of the wall 1 measure total photon and electron energy deposited. In simulation, place cylindrical lead (Pb) shield around HRRL, and see the change on the energy, if I change the thickness of that shield. This need to be done for both new and old (original) position of HRRL, so I can compare the ratio of the total energy deposited (electron and photon energy mixed) in new position to old position. Propose of this simulation is by comparing energy ratio, we have idea of radiation dose will be deposited on the cylindrical detector near the corner of wall 1.

# June/15/2010

1.)Emmittance measurement.

move magnet power supplies to Accelerator operator post ( 2 new supplies are in position, a box will be installed to hold 4 more new supplies) The rest of the space will be filled with the old, large, heavy power supplies as spares.

Ask kevin or chad about 120 Volt AC electrical connection for power supplies.  Do we have multiple circuits to avoid tripping the circuit breakers.?


Create an input file for Optim32 which represent the beam line for the emmittance measurements as shown at Emittance_Test. (done)

install wiring(at least 20 Amp capacity) for at least 2 quads in the HRRL which you will use for emmittance test

2.) Simulation

3.)Calculate impact of beam on Tungsten target in Vacuum
