Four-gap glass RPC as a candidate to a large area thin time-of-flight detector

TL;DR

This paper presents the development and testing of a four-gap glass RPC with ~100ps time resolution, suitable for large-area thin time-of-flight detection, with results on timing performance depending on pad size.

Contribution

It introduces a novel four-gap glass RPC with strip read-out achieving ~100ps resolution, useful for large-area timing detectors.

Findings

Achieved ~100ps time resolution with four-gap glass RPC

Demonstrated dependence of timing resolution on pad size

Provided data for designing large-area thin timing detectors

Abstract

A four-gap glass RPC with 0.3mm gap size was tested with hadron beam as a time-of-flight detector having a time resolution of ~ 100ps. A thickness of the detector together with front-end electronics is ~ 12mm. Results on time resolution dependently on a pad size are presented. This paper contains first result on the timing RPC (with ~ 100ps resolution) having a strip read-out. Study has been done within the HARP experiment (CERN-PS214) R&D work. A obtaned data can be useful if a design of a large area thin timing detector has to be done.
