“…It should also be noted that these three factors, smoothing, rise-time dependant delay, and total time selection can be implemented using more sophisticated analog methods [7], [11]. However, given the particular application considered here, involving field measurements carried out under difficult environmental conditions, such as those found in a humid cave under a pyramid, with limited access to electric power, etc., we have chosen an electronics setup in which the number of electronics modules is minimized.…”

“…Concerning MWPC readout, low counting rate applications often rely on simple delay line (DL) chains, which reduce the digitizing channels to two, instead of the direct reading alternative, having as many readout channels as wires. The main characteristics and related applications of delay-line readout techniques are discussed elsewhere [5]- [7]. Given the rough environmental conditions inherent to some practical applications (remote locations, humid tunnels, etc.…”

A readout method based on fast waveform digitalization is proposed which improves the performance of large multiwire proportional chambers (MWPCs) with delay-line readout. Atmospheric muon detection data are presented, obtained with a 1 m 1 m, 200 wire, MWPC and two plastic scintillators, having the same sensitive area, used for muon identification purposes. The performance of two alternative data acquisition configurations is compared: the standard one, based on analog constant fraction discriminators (CFDs), and one using 5 GS/s waveform digitizers in which a CFD-like analysis is performed offline. The latter is shown to provide better, and more uniform, space resolution, allowing to correct position-dependent rise-time variations across the detector. The new technique is applicable to low count-rate applications, such as muon attenuation measurements in large matter volumes.
