Title :
Domino Ring Samplers and the new dual readout fiber module
Abstract :
The dual readout technique consists measuring the electromagnetic fraction of an hadronic shower event by event by comparing the scintillation and Cherenkov light generated in the shower development process. Time characteristics of the signals produced by high energy particles in a fiber prototype module are sampled with a commercial VME board based on the Domino Ring Sampler (DRS) chip. The excellent timing resolution of the DRS-IV based acquisition can be used to recover spatial information on the shower location in a non segmented fiber module. The μs wide buffer opens the possibility of measuring the late neutron component of the hadronic shower.
