Abstract.Electron- multiplying charge-coupled devices are efficient imaging devices for low-surface-brightness ultraviolet astronomy from space. The large amplification allows photon counting (PC ...
in array detector manufacture. Quantum yield estimation for an electron - multiplying charge-coupled device from photon counting test data Robert Gleisinger Neil Rowlands Alan Scott Olivier Daigle Robert ...
to the electron multiplication before readout, the effective readout noise can be at the sub- electron level, enabling single photon counting . Traditional far UV (150 – 200 nm) imaging detectors have utilized micro ...
, with an opaque photocathode. The photocathode transforms, with typical quantum efï¬ciency 0 q 1, incoming photons into electrons ; each electron is then multiplied by one or more MCPs with a gain of 103 to 108 ...
to deposit opaque GaN(Mg) cathodes directly onto these MCPs. Keywords: Microchannel Plates, Imaging, Photon Counting , Photocathodes. 1. INTRODUCTION Microchannel plates (MCPs) have been used as electron ...
operating at a few eV, and followed by an electron multiplying detector, pulses due to individual electrons are counted . The overall efficiency of this process is essentially independent of gain drifts ...
We have developed the gas electron multiplier (GEM) for applying to a cosmic X-ray polarimeter. For a space use of the GEM, we performed experiments of charged particles irradiation to the GEM ...
an electron energy spectrometer operating at a few electron volts, and followed by an electron multiplying detector, pulses due to individual electrons are counted . The overall efficiency of this process ...
with gain (e.g., Avalanche Photodiodes or APDs or electron multiplying charged-coupled devices or EMCCDs) enables photon - counting capabilities in solid state format ...
the Multi Anode Photo Multiplier Tubes (MAPMTs). UV photons are converted by the MAPMT photocathode into electrons , which are multiplied by the MAPMTs dynode and fed into a Elementary Cell - Application ...
