High collection efficiency MCPs for photon counting detectors

High-efficiency single-photon detectors.

Visible light photon counters (VLPCs) and solid-state photomultipliers (SSPMs) are high-efficiency single-photon detectors which have multi-photon counting capability. While both the VLPCs and the SSPMs have inferred internal quantum efficiencies above 93%, the actual measured values for both the detectors were in fact limited to less than 88%, attributed to in-coupling losses. We are currently...

High Accuracy Calibration of Photon-Counting Detectors

We discuss a practical implementation of a photon-counting detector calibration using correlated photon pairs produced by parametric down-conversion. In this calibration scheme, the detection of a first photon triggers the measurement sequence aimed at detection of a second photon by a detector under test (DUT). We also describe measurements of radiant power with a photon-counting detector, whi...

High-Efficiency Error Correction for Photon Counting

Today's data-driven society demands high data rates and high-rate communication links. Addressing these needs in everything from gigabit Ethernet network connections and telephone or cable television signals to communication between spacecraft can require high bandwidth, high power, large transmit or receive apertures or both, and high receiver sensitivity. Optical communication is attractive f...

High efficiency Transition Radiation Detectors for high counting rate environments

One of the options currently considered for lepton identification with the CBM experiment [1] for FAIR is a shell of multiple layers of Transition Radiation Detectors (TRD). Being a heavy-ion fixed target experiment in the energy range of 5-35 A·GeV the goal of CBM is to look for rare probes using the unique performance of FAIR in terms of high intensity heavy ion beams. This requires a high gr...
