plastic scintillator muon detector

The most probable value of the muon distribution can be determined with a local Gaussian fit to be \(\sim \)3063FADC a.u., corresponding to muons impinging vertically with an average energy deposition in the plastic scintillator of around 10MeV. Direct Interactions between Radiation and Detector: Ideally, the photodetector would only generate a signal when photons originating from the scintillation fiber enter the detector. On the basis of these findings, the disk-shape plastic scintillator-based muon veto has been assembled and commissioned at room temperature.

Find Dr. Doezie's phone number, address, hospital affiliations and more. This cryogenic muon veto prototype is being operated within a customized copper holder on top of the still stage of the NUCLEUS cryostat and thermally coupled to a temperature of T\(_{still}\)\(\sim \)850mK. JHEP 2005(12), 021 (2005). The muon-induced neutrons, which are particularly harmful due to the same experimental signature as the sought-for CE\(\nu \)NS (i.e., a nuclear recoil) can be reduced passively via moderation and absorption in polyethylene. Averaged for a number of pulses, it can be observed that the pulse decay time is enhanced by 32% at sub-Kelvin temperature. The desktop muon detector is a self-contained apparatus that employs a plastic scintillator as the detection medium and a silicon photomultiplier for light collection. The pulse decay time of the scintillator, which is defined as the time after which the pulse has returned to 1/e of its peak value, has been observed to increase from t\(_{decay,\,room}\)=47ns at room temperature to t\(_{decay,\,still}\)=64ns at still temperature. In order to prevent a large unshielded area where the cryostat intersects the shielding arrangement without unnecessarily increasing the induced detector dead time, a novel concept has been investigated, featuring a plastic scintillator-based active muon veto operating inside the NUCLEUS cryostat at sub-Kelvin temperatures. Very nice eBayer with fast transaction and nice items. Given the scarcity of experimental studies on the thermalization behavior and the scintillation mechanism of organic plastic scintillators at sub-Kelvin temperatures, a proof-of-concept detector has been conceived in order to validate the feasibility of the intended NUCLEUS cryogenic muon veto detector concept. To develop a device of large-area cosmic ray imaging in complex measurement environments, we design a muon scattering imaging detector composed of triangular scintillators, with a new type of photodetector (SiPM) as readout. https://doi.org/10.1103/PhysRevD.9.1389, J.

Dr. Doezie takes the time to listen and understand his patients needs and provides them with the necessary information they need before their procedure. Plastic scintillators have several desirable qualities including near tissue equivalency, small size limited by the ability to detect small amounts of light, and energy independence in the MV range. The plastic scintillator material is EJ-200 by Eljen Technology and consists of polyvinyl toluene with organic fluors and a scintillation efficiency of 10,000 photons/MeV. Meth. These detectors can be battery powered and used in . Eventually, the researchers would like to apply their pocket detector as a means of muon tomography, a technique that uses the distribution of muons to create a three-dimensional image of the amount of material surrounding a detector. Optical Cement BC-600. The thermalization behavior of organic plastic scintillators has been investigated for a sample of the polyvinyltoluene-based plastic scintillator EJ-204 [15]. The timing of the muon coincidences will be governed by the slow rise time of \({\mathcal {O}}\)(100\(\mu \)s) of the cryogenic target neutrino detectors.
