The applications of Resistive Plate Chambers (RPCs) have recently been extended by the development of counters with time resolution below 100 ps s for minimum ionising particles. Applications to HEP experiments have already taken place and many further applications are under study. In this work, we address the operating principles of such counters along with some present challenges, with emphasis on counter ageing. Possible applications to radioisotope imaging will be outlined. r

“…In such a high electric field, the process, once started, goes on until practically all gas in the cell is ionized; an uncontrolled discharge can be prevented by restricting the electric field by space charge effects and/or by external means, e.g., a resistor in the HV bias chain, as in the Geiger counter. In our design, the discharge stops when the voltage across the cell drops due to the high-volume resistivity of the cathode; this is similar to the limited streamer process occurring, e.g., in Resistive Plate Chambers (RPC) [5]. The discharge is restricted not only in time but in space, as it remains confined to the cell where it started.…”

A detector array for single-ion registration was developed and studied. The detector array was operated with various working gases, including propane, air, and water vapor at low gas pressure (a few mbar) in a limited Geiger mode, providing single ion sensitivity. The patterned detector structure, comprising sub-millimeter hole diameter, millimeter pitch, ground and 2D readout electrodes, were manufactured using standard PCB technology. A glass cathode was utilized to allow the limited discharge mode of operation. Essentially, the new detector is a combination of a hole-type micro-pattern detector and a resistive plate counter operating at reverse polarity in a low pressure gas. It was demonstrated that the unique combined properties of these well established individual detectors in the low pressure gas environment allows for single ion registration through ion-impact induced discharge confined inside an individual cell (hole) of the detector array. Possible applications of the new ion detector in gas chromatography-mass spectrometry and track structure imaging for radiation protection and hadron therapy are briefly discussed.

“…This can be understood when looking at Fig. 11a and it is a well-established fact for detectors like Resistive Plate Chambers [13], where avalanche fluctuations dominate the signal characteristics [14,15]: scaling the threshold by a constant c 1 will just shift the time response function by ∆t = (ln c 1 )/λ t without altering its shape. If we are not interested in the absolute time of the threshold crossing but just the time variations we can arbitrarily set n = 1 and have the time response function…”

We give an analytic treatment of the time resolution and efficiency of Single Photon Avalanche Diodes (SPADs) and Silicon Photomultipliers (SiPMs). We provide closed-form expressions for structures with uniform electric fields and efficient numerical prescriptions for arbitrary electric field configurations. We discuss the sensor performance for single photon detection and also for charged particle detection.
