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.

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.?
Map quads Instruments_and_Equipments#Mapping_Quadruple_Megenets
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

Prepare for emittance test.
1) Power wiring for quad. Use the wire used for old dipole, and bring power 20-Amp supply in IAC.
2) Figure out how to use flag. (done)
3) Install water cooling for the quad.
July/09/2010
1) Power for light and control (actuater) for Flag. Control for flag. (done)
2) Fix the stand for Flag.(done)
3) Find the center of the quad. (done:Khalid said geometrical center is the magnetic center)
4) Bolts and cables for FC.(bolts found, need find cables.)
5) Water for quad.(Pipe need metric bolts.)
Aug/09/2010
1) Write radiation foot print report.
2) Trig camera and take picture.
3) Order a cable for camera.
4) Data analysis on HRRL emittance.
5) Look at the paper on how to do OTR with Al.

2/22/11
1.) New camera installed with shielding and a sample image showing the holder takes up most of the field of view
2.)Camera cage to beam line adapter plate may need to be re-machined. For now we will try a second plate to create a sandwich around the top cage holder.
3.)Check that light in flag is not usable. If not usable build external light in an enclosure. Replace the glass window with the quartz window and put the glass window on the side of the six cross.
4.)Alignment proceedure. Is it the quad or the target misaligned?
5.) Mapping quad, can be done after emittance.
