1- Schedule

2- Design of beamline, radiator and dump

• Experiment beam line today is presently decommissioned, ready for modification:

3- Bubble Chamber work at Argonne

4- Background and simulation

5- Absolute beam energy

• One slide on beam momentum Media:130724_Bubble_Grames.pdf

6- Safety

Notes from this meeting:

- The power deposited in the radiator for 200 uA and 8.5 MeV electron beam:
  For 0.02 mm radiator, average energy loss is 24 keV, P = 4.8 W
  For 0.10 mm radiator, average energy loss is 120 keV, P = 24 W

- Need a HARP in the new Bubble Chamber line to measure the size of the beam impinging on the radiator
