CMS Hadron Calorimeter. Andris Skuja Lv.2 HCAL Project Manager’s Overview US CMS Annual Meeting Riverside, California May 19, 2001. System Overview. HCAL: US does all of HB and optical cables, transducers, front end and readout electronics for HO, HE and HF. HO. HB. HF. HE.
HB- absorber is complete. It passed all QC tests and has been disassembled and shipped to CERN.
HB- wedges and scintillator crates in Bldg 186 at CERN. Scintillators will be installed into wedges in June.
Interior of vacuum vessel for superconducting magnet.
The HBs rest on the rail.
12 of 18 HB+ Wedges are complete
Cradle and tooling ready
HB+ will be complete by end of July, ahead of schedule
Cable block stabilizer
Components are the machined scintillator plates, cover plates, fiber assembly (WLS spliced to clear fiber, optical connector) pigtails
