Muon Detector Performance (4/17/01)

This page is the starting point for information related to the muon detector's performance during Run II. It will include online histograms such as hit maps, time and pulse height plots. It will also include, or point to, information on detector efficiencies and detector resolutions.

Central Scintillators

The central scintillators consist of 630 A-layer, 80 B-layer (one the bottom and lower sides), and 276 C-layer counters. The B- and C-layer counters each have two PMTs while the A-layer counters have one. Pulse height is read out for 1 out of every 16 channels. The counters are divided into octants (0-7) and barrels (0-4) with finer divisions descibed in central counter map .
