Large-area, flat-panel photo-detectors with sub-nanosecond time resolution based on microchannel plates are provided. The large-area, flat-panel photo-detectors enable the economic construction of sampling calorimeters with, for example, enhanced capability to measure local energy deposition, depth-of-interaction, time-of-flight, and/or directionality of showers. In certain embodiments, sub-nanosecond timing resolution supplies correlated position and time measurements over large areas. The use of thin flat-panel viewing radiators on both sides of a radiation-creating medium allows simultaneous measurement of Cherenkov and scintillation radiation in each layer of the calorimeter. The detectors may be used in a variety of applications including, for example, medical imaging, security, and particle and nuclear physics.

Use of flat panel microchannel photomultipliers in sampling calorimeters with timing

A detector for detecting a particle is disclosed. The detector includes a charge emitter that emits a charge in response to receipt of the particle, an anode for receiving the emitted charge, and electronics for determining whether there is received charge on the anode. The anode may include a pad for receiving the charge and a plurality of conduits (such as transmission lines) for transmitting the charge to the electronics. The anode may be designed to reduce the variance in the path length from the pad of the anode to the electronics. For example, the plurality of conduits in the anode may be constructed such that the transit time of the charge from the pad varies less than a predetermined time. Further, a capacitive element may be included in the detector in order to capacitively couple with the charge emitter. The capacitive element may include a grid that is in the same layer as the pads of the anode in order to provide a short and less variable circuit return path to the charge emitter.
