This manuscript describes the commissioning of Mini-CAPTAIN liquid argon detector in a neutron beam at Los Alamos Neutron Science Center (LANSCE), which led to first measurement high-energy interactions argon. The consists Time Projection Chamber (TPC) with an accompanying photomultiplier tube (PMT) array sealed inside liquid-argon-filled cryostat. is constantly purified and recirculated closed...

A relatively new photodetector, the silicon photomultiplier (SiPM), is well suited for PET applications. It has similar sensitivity and gain to the industry standard photomultiplier tube (PMT), but has advantages such as smaller size and insensitivity to magnetic field. These properties make this detector an active area of research in the PET field. I will study a simplified setup, comprised of...

A relatively new photodetector, the silicon photomultiplier (SiPM), is well suited for PET applications. It has similar sensitivity and gain to the industry standard photomultiplier tube (PMT), but has advantages such as smaller size and insensitivity to magnetic field. These properties make SiPMs an active area of research in the PET field. I will study a simplified setup, comprised of two ant...

A graphical program was created, to simplify the acquisition of data and data conversion from bin to ASCII, for data obtained by a Stanford Research Multichannel Scaler/Averager (SR430). The SR430 receives the data in the form of pulses from a photomultiplier tube (PMT). The PMT serves as the detector in a pulsed laser spectroscopy experiment. The program was created in LabVIEW TM which was dev...

A flow-injection (FI)-based instrument under LabVIEW control for monitoring iron in marine waters is described. The instrument incorporates a miniature, low-power photomultiplier tube (PMT), and a number of microelectric and solenoid actuated valves and peristaltic pumps. The software allows full control of all flow injection components and processing of the data from the PMT. The optimised sys...

The Antarctic Muon And Neutrino Detector Array (AMANDA) is a high-energy neutrino telescope. It is a lattice of optical modules (OM) installed in the clear ice below the South Pole Station. Each OM contains a photomultiplier tube (PMT) that detects photons of Cherenkov light generated in the ice by muons and electrons. ICECUBE is a cubickilometer-sized expansion of AMANDA currently being built ...

Optical detection is reliable in intrinsically characterizing partial discharges (PDs). Because of the great volume and high-level power supply of the optical devices that can satisfy the requirements in photosensitivity, optical PD detection can merely be used in laboratory studies. To promote the practical application of the optical approach in an actual power apparatus, a silicon photomultip...

Every large ICF laser facility, including Nova, OMEGA, and GEKKO, uses neutron time-of-flight (nTOF) systems to measure neutron yields and ion temperatures. Such nTOF systems are usually based on current-mode detectors consisting of a fast plastic scintillator optically coupled to a fast photomultiplier tube (PMT). A high-bandwidth transient digitizer records the signal. These systems, which ar...

The gas proportional scintillation counter/microstrip gas chamber (GPSC/MSGC) hybrid detector for X-ray spectrometry is described. The detector uses a CsI-coated microstrip plate placed in direct contact with the gas-filling as the photosensor readout for the GPSC scintillation substituting for the photomultiplier tube (PMT). Usable photosensor maximum gain is limited by optical positive feedba...

We present an architecture of controlling a proposed spectrometer system for detecting pollution in water and gas. The system is based on LED sensors using a Michelson interferometer and stepper –motor for moving split mirrors. The system is designed so that changes in LED light intensity could allow to detect a wide spectrum of polluted substances. The architecture uses a special duty-cycle to...
