The FXE beamshutter key has been installed into the interlock system after satisfactory completion of the FXE Chicane and Radiation Protection Sticker Checklist. The FXE Experiment hutch is now ready to receive xfel beam as required by the FXE instrument group.

However, the bunch mode MUST be limited to 1 or 2 bunches until the new user chicane is tested with thirty bunches using the copper target. This can be done whenever the parameters can be practically put into place. The test will be similar to the hutch commissioning where once it has been confirmed that the beam is on target. I will take radiation measurements at the chicane. This is the only place where radiation measurements will be required. Please provide me as much notice as possible prior to the date and time that 30 bunches will be brought into the FXE Experiment hutch.

I have also place 3 additional area monitoring dosimeters in the FXE Experiment. One on the robot arm where the D3 pandora place holder is. One above the old user chicane on the D.05 side and one inside the new user chicane on the control room side.
