It is widely accepted that coregistration of anatomical information improves the diagnostic value of functional imaging. At the moment, this is reflected in the success of hybrid scanners using PET and CT imaging. But the combination of PET and MR imaging may also offer advantages, such as higher soft tissue contrast in the MR anatomical images, real simultaneous acquisition, and minimum radiat...

We propose two types of neutron-$\gamma_1$-$\gamma_2$ triple coincidence detectors (not constructed) to chase gamma transitions produce p-nuclei following the neutron emission in $(\gamma, n)$ reaction. Neutrons are detected with 24 $^3$He counters embedded a polyethylene moderator Type I detector and 6 liquid scintillation II detector, respectively. $\gamma$ rays high-purity germanium four LaB...

Scintillating fibers are widely used in particle detectors, mainly for tracking. We have studied the properties and compared performance of different blue-emitting 250~$\mu$m diameter round double-clad scintillating from Kuraray Saint-Gobain. Here we focus on over short lengths ($< 50~{\rm cm}$), particular their timing performances. report light yield attenuation, scintillation decay time achi...

UNLABELLED It has been long recognized that the primary advantage of imaging the brain with a positron emission tomography using GSO scintillation detectors placed on a spheroid surface is the large solid angle of acceptance for annihilation radiation, which results in improved system sensitivity and image signal-to-noise ratio. In the present study, we investigated spheroid system geometry, de...

The TAIGA gamma observatory is continuing its deployment at the Tunka valley, close to lake Baikal. new, original detectors, able work under severe conditions of Siberia, were developed increase sensitivity for study gamma-quanta energies about 1 PeV and above. distinguishing feature detectors use wavelength shifting light guides scintillation collection on a photodetector. Several designs coun...

In this bachelor thesis, which is a part of the project RadioRoSo, we examine and analyze waste from Magnox power plants. These power plants were mostly situated in the Great Britain and they were operated between 1956 and 2015. The analyzed waste mainly consists of pieces of Magnox alloy AL80. Springs from alloy Nimonic 80A are also present in the waste and they are considered to be highly rad...

We have developed a detector, consisting of a cryogenic calorimeter with a scintillating crystal as absorber, and a second calorimeter for the detection of the scintillation light, both operated at 12 mK. Using a CaWO4 crystal with a mass of 6 g as scintillating absorber, we have achieved a discrimination of nuclear recoils against electron recoils with a suppression factor of 99.7% at energies...

SpecMAT is a magnetic active target (AT) for transfer reaction studies with low-intensity radioactive ion beams at the ISOLDE facility (CERN). combines two types of detectors: gas-filled time projection chamber (TPC), core detector tracking charged particles emitted in nuclear reactions, and an array auxiliary scintillation detectors in-flight γ-ray spectroscopy. All components are optimised op...

Development of a small area (1–2 cm) in situ beta imaging device includes optimization of the front end scintillation detector, which is fiber optically coupled to a remote photon detector. Thin plastic scintillation detectors, which are sensitive to charged particles, are the ideal detectors due to the low sensitivity to ambient gamma backgrounds. The light output of a new binary plastic scint...
