The world is not divided by iron curtain anymore. In case the signal-to-noise ratio remains large enough in the subsequent reconstruction of the EAS events, lowering the PMT gain in such conditions can be an option to avoid faster ageing. The multipactor effect was suppressed for two waveguides, even when applying the maximum available power levels. We will never know why L.A. Kubetsky's name was buried in oblivion in the West. We have no right to judge and we cannot do it. This allows to extend the measurement cycles of experiments, based on PMTs of type Photonis XP3062 or comparable and exposed to the NSB, to enhance the sensitivity especially at the highest energies where events are very rare. Both the BMTF and μGMT have been implemented in a Xilinx Virtex-7 card utilizing the microTCA architecture. Our … Photomultiplier tubes are used to detect low levels of incident light, even as low as a single photon. One part of this upgrade is the re-organization of the muon trigger path from a subsystem-centric view in which hits in the drift tubes (DT), the cathode strip chambers (CSC), and the resistive plate chambers (RPC) were treated separately in dedicated track-finding systems to one in which complementary detector systems for a given region (barrel, overlap, and endcap) are merged at the track-finding level. It is difficult if not possible to, to find the origin of the idea of using cascaded stages of secondary emission to obtain electron current amplification.

Photomultipliers are highly sensitive photon detectors. The high internal gain of SiPMs, together with other features peculiar of the silicon technology like compactness, speed and compatibility with magnetic fields, promoted SiPMs as the principal photo-detector competitor of photomultipliers in many applications from radiation detection to medical imaging. Photomultipliers (PMTs) are the most widespread vacuum electronic devices. An overview will be given of the new track-finder system for the barrel region, the Barrel Muon Track Finder (BMTF), as well as the cancel-out and sorting layer: the upgraded Global Muon Trigger (μGMT). In this study, we consider using LEDs to stimulate the recovery of scintillators damaged from radiation in high radiation environments. We hypothesize that the ‘green’ scintillators require wavelengths that match their absorption and emission spectra for LED stimulated recovery. Two different high-dose irradiations took place, with PEN dosed to 100 kGy, and the others to 78 kGy. It is our tribute to the memory of great Soviet-Russian physicist and engineer Leonid Aleksandrovitch Kubetsky whose life and scientific achievements are described briefly. In 1923, he started to study physics at the Faculty of Physics, Least of all we would like to shake authority of V.K. An incoming photon will strike the photocathode surface of the PMT which will emit electrons. While the BMTF improves on the proven and well-tested algorithms used in the Drift Tube Track Finder during Run-1, the μGMT is an almost complete re-development due to the re-organization of the underlying systems from track-finders for a specific detector to regional track finders covering a given area of the whole detector. Now it is time to restore historical justice and to pay tribute to a great physicist and engineer Leonid Aleksandrovitch Kubetsky. Conversely exposing the ‘green’ scintillators (EJ-260) to LED light had a nearly negligible effect on the recovery. It is my humble attempt to accomplish my teacher's desire. We hypothesize that the ‘green’ scintillators require wavelengths that match their absorption and emission spectra for LED stimulated recovery.

The fully scalable concept overcomes the dilemma of sensitivity versus spatial resolution which is inherent to classical PET designs. The device is a vessel placed into a … A photomultiplier tube uses two scientific principles to amplify the effect of a single incident photon. Almost 20 years ago he was going to write a paper on the PMT history and publish it in an international journal. Vacuum tubes we still (have to) use: The photomultiplier tube, Part 1 November 18, 2019 By Bill Schweber Maybe we can’t live with them, but we can’t live without them, at least not yet: the photomultiplier tube and the traveling wave tube are two vacuum electron-tube devices that are still viable and needed in our solid-state world.) Two different high-dose irradiations took place, with PEN dosed to 100 kGy, and the others to 78 kGy. The tube is often bent and has a photocathode situated inside, behind the taking lens. The 1986 acquisition of RCA by General Electric resulted in the divestiture of the RCA Lancaster New Products Division. Photomultiplier tubes (often abbreviated as PMT) make use of this external photoelectric effect and are superior in response speed and sensitivity (low-light-level detection). Particular efforts are made to shed light on a controversial issue of who invented the first photomultiplier tube. The development of devices with internal gain, avalanche photodiodes (APD) first and then Geiger-mode avalanche photodiodes, named single photon avalanche diode (SPAD), leads to a substantial improvement in sensitivity and allowed single photon detection. Particular emphasis is given to latest advances on Positron Emission Tomography instrumentation boosted by the adoption of the silicon photo-detectors as an alternative to photomultiplier tubes (PMTs). A photomultiplier tube, useful for light detection of very weak signals, is a photoemissive device in which the absorption of a photon results in the emission of an electron.
