Dream Testbeam December 2014

Shift schedule: December beam

Program

Dec 1 to Dec 3
Al Cu module, 20 GeV positron

• Electromagnetic energy resolution as a function of rotation angle: +5 to -5 degrees
• 4 scans done with 2 and 1 degrees tilted module, with and without preshouer . Low energy wobbling
  
• Calibration of each Pb tower with electrons, AD readout
• Calibration with electrons DRS readout of some of Pb towers

Machine Development
Open the calorimeter box, remove PMTs of copper, remove with the crane the Cu modules, close the box, install on the top leakage counters
Dec 3 evening to the end
Pb 3*3 matrix

• Time structure of hadronic signal. DRS readout. Pb matrix plus leakage detectors. 180 GeV pions and lower energies.
• Hadronic energy resolution, pion 180 GeV, 125, 80, 40, 20, 15
