Abstract

We have developed multi-gap resistive plate chambers (MRPCs) with 2.5×200 cm ² readout strips for the time-of-flight (TOF) detector system of the LEPS2 experiment at SPring-8. These chambers consist of two float glass stacks with 5 gas gaps each, in a mirrored configuration. A time resolution of σ≃80 ps was achieved for any position within a strip (at above 99% detection efficiency), improved to 60 ps after correcting for a relatively small time-charge slewing effect. This latter fact seems to stem from the suppression of modal dispersion, achieved through convenient design choices.
