Sealed Gas UV-Photon Detector with a Multi-GEM Multiplier
نویسندگان
چکیده
A sealed gas photon detector with a GEM (Gas Electron Multiplier) cascade coupled to a semitransparent CsI photocathode has been studied. High gains, reaching 10, and fast anode signals, of a width of 15 ns, were obtained with this GEM-Photomultiplier in Ar/CH4 (95/5), in a photon counting mode. The life-time of this first prototype detector under high photon flux and large anode currents is provided.

Single photoelectron detection with a low-pressure gas electron multiplier coupled to a CsI photocathode
We have operated the Gas Electron Multiplier (GEM) coupled to a CsI photocathode for the detection of single UV photons. Gains of up to 10 000 were observed with a single GEM in pure hydrocarbons in the range 40}400 Torr. Using a double-GEM structure, we have detected single photoelectrons on a strip electrode. We have studied the single-electron detection e$ciency of the GEM, a crucial paramet...

PANDA experiment (antiProton ANnihilation at DArmstadt) is one of the key projects of the future FAIR facilities to investigate the reactions of antiprotons with protons and nuclear targets. experiment is designed to serve as a completely extraordinary physical potential due to exploiting the availability of cold and high-intensity beams of antiprotons. One of the significant parts of the ...
متن کاملDevelopment of a large area gas photomultiplier with GEM/μPIC
We are developing a new photon detector with micro pattern gaseous detectors. A semitransparent CsI photocathode is combined with 10cm×10cm GEM/μPIC for the first prototype which is aimed for the large liquid Xe detectors. Using Ar+C2H6 (10%) gas, we achieved the gas gain of 10 which is enough to detect single photoelectron. We, then, irradiated UV photons from a newly developed solid scintilla...

متن کاملDevelopment of a two-dimensional virtual-pixel X-ray imaging detector for time-resolved structure research.
An interpolating two-dimensional X-ray imaging detector based on a single-photon counter with gas amplification by GEM (gas electron multiplier) structures is presented. The detector system can be used for time-resolved structure research down to the micro s time domain. The prototype detector has been tested at the SAXS (small-angle X-ray scattering) beamline at ELETTRA synchrotron light sourc...
