October 14, 2006 - MGH Run

At Mass General Hospital's Proton Therapy Facility, the CRaTER team had their first calibration run with the CRaTER Engineering Model (EM). There were several objectives for the beam test:

1. Conduct the first exposure of the CRaTER Engineering Model (EM) to an ion beam
2. Verify that the EM operations concept will work during the beam run at BNL the following week
3. Produce a signal above the threshold in each of the detectors
4. Collect measurements at a fixed proton energy with varying rate to examine the stability of the response of the system as a function of the rate
5. Test the operation of the coincidence mask
6. Accumulate peaks at several energies in each of the thick detectors

The CRaTER team was successful in meeting each objective at this run. They also constructed a mount to be used (also for the first time) during this run, and they anticipate using it for general transportation of the EM as well as during future runs at BNL.
