Abstract We present results of several measurements CsI[Na] scintillation response to 3–60 keV energy nuclear recoils performed by the COHERENT collaboration using tagged neutron elastic scattering experiments and an endpoint technique. Earlier results, used estimate coherent neutrino-nucleus (CEvNS) event rate for first observation this process achieved at Spallation Neutron Source (SNS), have...

We present the results of Hamamatsu R5912 photomultiplier tube modelling and simulating. The model can be adapted to any architecture by changing number electrodes, voltage distribution, intrinsic PMT parameters. Our approach solves use tapered dividers allows simulations under stimulation conditions. implementation is not limited SPICE-based software but also used with compiled interpreted pro...

Two micro crystal element (MiCE) detector unit designs are evaluated. The detector units are built using highly packed arrays of 0.8 0.8 6 mm mixed lutetium silicate (MLS) crystals. The first detector unit, MiCE1, consists of a 5 5 array of 0.8 mm 0.8 mm 6 mm MLS crystals. The detector unit is coupled to four channels of a Hamamatsu multichannel photomultiplier tube (PMT) via a 2 2 array of 2 m...

This paper describes a simple, inexpensive transimpedance amplifier (TIA) suitable to convert the fast current pulses delivered by photomultiplier tube of night airglow photometer into the corresponding voltage. Design criteria for the transimpedance amplifier are carefully selected to include low input bias current, offset voltage and noise. The operation of the transimpedance amplifier and th...

MOTIVATION Pixel saturation occurs when the pixel intensity exceeds a threshold and the recorded pixel intensity is truncated. Microarray experiments are commonly afflicted with saturated pixels. As a result, estimators of gene expression are biased, with the amount of bias increasing as a function of the proportion of pixels saturated. Saturation is directly related to the photomultiplier tube...

Within the Crystal Clear Collaboration (CCC), four centers are developing second generation high performance small animal positron emission tomography (PET) scanners for different kinds of animals and medical applications. The first prototypes are photomultiplier tube (PMT)-based systems including depth of interaction (DOI) detection by using a phoswich layer of lutetium oxyorthosilicate (LSO) ...

Each of two detectors used in our Positron Emission Mammography (PEM) system consists of four 36 mm x 36 mm x 20 mm bismuth germanate (BGO) crystal detector blocks coupled to a crossed-wire anode position-sensitive photomultiplier tube (PS-PMT). To facilitate high spatial-resolution imaging, the crystal blocks have been finely pixelated using a diamond saw. In each detector, 36 x 36 1.9 mm x 1....

Due to its sensitivity and speed, the detector still widely used in Cerenkov astrophysics experiments remains the PhotoMultiplier Tube (PMT). For instance, recent pathbreaking experiments in Very High Energy astrophysics (VHE), such as MAGIC and HESS, have used mainstream PMT technology (Aharonian et al, Astron Astrophys 492(1):L25–L28, 2008). Moreover the Cerenkov Telescope Array (CTA) which i...

The ClearMind project aims to develop the TOF-PET position sensitive detection module optimized for time resolution, spatial and efficiency. For this, uses a large (59 × 59 mm2) monolithic PbWO4 (PWO) scintillating crystal with bialkali photo-electric layer deposited directly on crystal. Scintillation Cherenkov photons result together from 511 keV gamma-ray interaction into PWO A micro-channel ...

Specialized soft x-ray and vacuum ultraviolet ~VUV! diagnostics used to monitor impurity emissions from fusion plasmas are often placed in a very challenging experimental environment. Detectors in these diagnostics must be simple; mechanically robust; immune to electromagnetic interference, energetic particles, and magnetic fields up to several tesla; ultra-high-vacuum compatible; and able to w...
