DESY 2017 BT demand

Project name and short description : CALICE SiW-ECAL

– An imaging ECAL for the ILD; this technological prototype features 12 layers (12k channels) separated by a variable

amount of tungsten (0–2X0).

– Responsible Person : Vincent Boudry – Participating Groups: CNRS-LLR, CNRS-LAL, CNRS-LPNHE, CNRS-LPSC + (optionally) U. Kyushu, – Number of requested weeks: 2 weeks – Preferred month(s) : June – Required infrastructure (beam telescope, magnetic field, gas, stages) : optionally EUDET/AIDA beam telescope – Irradiated samples: None

The purpose of the BT are two fold: 1- test our devices (10 layers of Silicon-Tungsten) first without B-field in «quiet condition»: we suffered from the noisy environment at CERN in June, and want to insure that we get all the devices running. DESY is for this much more relax that CERN: less stress and low energy electron beam + support from our DESY colleagues. 2- If possible (i.e. goal 1 achieved) run them in the magnetic field with the highest possible field, so that we check that Power pulsing in B field is possible, in transverse (Barrel case) and longitudinal (endcap case) directions. Our device is ~ 45 cm in height and depth × ~80 cm in width.

Physics program

“As many SLABs as possible” ⇒ 5–10 Run with electrons

– Punch through (no W)

  • Check response of mip like at low rates

– Optionally at angle (45°) → ×√2 in mean signal

  • vary beam & DAQ rate & conditions (Nb of SLABs)

– Comparison with cosmics

– Full calorimeter (20 X0):

  • Check response with beam & DAQ rate & conditions (Nb of SLABs)

– Test a couple of SLAbs in B field

  • PCMAG (1Tesla Solenoid Ø≈85 cm, TB24/1), but the telescope would not fit in easily and the weight might be a problem.
