Background at LCcalPanic limit: 1% occupancy in the detector

Si detectors excluded from evaluation.

Assumed: 10000x3 Sc. Channels

Guessed values:

• muons: 6/BX inside the detector (with the pessimistic assumption that a crosses the whole detector)

• hadrons from minijets: 100xEmip= 25 GeV/BX (also for n)

•Photons: N<100x Emip/Eγ~10000 (for Eγ=2.5 MeV)

•Rad Bhabhas: 10/BX.

Background at ShashlikPanic limit: 1% occupancy in the detector

TDR: 44000 channels

Guessed values:

• muons: 3.4/BX inside the detector (with the pessimistic assumption that a crosses the whole detector: >100 hits)

• hadrons from minijets: 400xEmip= 100 GeV/BX

•Photons: N<400x Emip/Eγ~40000 (for Eγ=2.5 MeV)

•Rad Bhabhas: 10/BX.
