Update on the Muon detector layout and readout channel number Burkhard Schmidt 28.03.2011
What was wrong previously • The barrel and end-cap yoke of CLIC ILD, is not an octagon but a dodecagon. • Thanks to Erik for pointing this out to me • This is still wrong on some of the drawings for the infrastructure. • For CLIC SiD, this is indeed an octagon. • NB: opposite to ILD, SiD has a dodecagon inside the coil for ECAL and HCAL. ILD has here octagons. • Is all this motivated by physics . . . ?
Update on area to be covered CLIC - SiD: Comments: • In case of scintillators as technology, 2 layers are mandatory to get the 2 coordinates. • Area went up by about 25m2/layer • Single layer for CLIC-ILD a bit larger due to bigger solenoid • Area went up by about 125m2 since last time. CLIC - ILD:
Channel numbers CLIC-SiD CLIC - SiD: Comments: • Large difference comes from the end-caps • SiD doesn’t take into account that long vertical strips are not feasible. Barrel: 5.7 m long; 14 barrels; axial 10, 025 ; (r,f) 15,570 Sum 25,595 Forward/Backw’d (x,y) Quads RFe = 5.5 m, 4 quads X2 (x,y) [1,072] 14 planes X2 forw/back F+W 30, 016 Readout ch’s25,595 + 30,016 = 55,611 Standard SiD:
Update on channel numbers CLIC-ILD CLIC - ILD: Comments: • Assumed a full pad readout. • The HARDROC chip (64 channels) but also the present version • of the 64 channel version of the KPIX chip seem to be suitable.
