Dream Testbeam December 2015

Program

Al Cu module, Al C fibers, with one tower equipped with MCP readout S and C

• module perpendicular to the beam, scan in X and theta angle, electron beams, DRS readout, 2 channels. Look at the reflected signal (time time distance, attenuation)
• module parallel to the beam, theta 1 degree, pion beam 20 GeV. Time structure studies (with CET counters to select pions/protons)

Pb 3*3 matrix * Hadronic energy resolution, pion 180 GeV, 180, 125, 80, 40, 20, 10, 60. Calibration with electrons 20, 40 GeV * DRS readout, proton, pion shower profile
