Abstract
Experimental Hall B at Jefferson Laboratory houses the CEBAF Large Acceptan ce Spectrometer, the magnetic field of which is produced by a superconducti ng toroid. The six coils of this toroid divide the detector azimuthally int o six sectors, each of which contains three large multi-layer drift chamber s for tracking charged particles produced from a fixed target on the toroid al axis. Within the 18 drift chambers are a total of 35,148 individually in strumented hexagonal drift cells. The novel geometry of these chambers prov ides for good tracking resolution and efficiency, along with large acceptan ce. The design and construction challenges posed by these large-scale detec tors are described, and detailed results are presented from in-beam measure ments. (C) 2000 Published by Elsevier Science B.V.
