Hall C

Hall C is one of three experimental halls at JLab.

Hall C Computing.

Hall C in the Press.

Data Acquisition

The Hall C data acquisition digitizes data from the drift chambers, hodoscopes, Cerenkov detectors and lead glass shower counters that are located in the HMS and SOS shield huts. This digitization is done with Lecroy fastbus modules located in 4 crates.

The ~2000 channels of drift chamber signals are discriminated and the times of hits on wires are recorded in fastbus crates located in each of the spectrometer huts. These times are digitized with Lecroy 1877 multihit TDC's with a resolution of 0.5ns.
