E. Hazen -- MaPSA-Light Testing Status / Plans First test beam campaign Oct 28 – Nov 11 120 GeV protons from FNAL main injector Readout counters (asynchronous) and hits (synchronous) modes Promising results, lots of data taken Integration with machine trigger was attempted during the test beam and didn't quite work Working on firmware/software now for next run starting Dec 11th. 2015-12-17 E.
