Abstract For fast neutron sources, such as compact generators, it is desirable to have knowledge and ideally directly measure the energy spectrum of generated neutrons. neutrons, produced radiation field, spectrum, at a specific location from source, can be altered by distance source become even significantly distorted surrounding material — e.g. walls floor laboratory. To achieve this goal, we make use Time-of-Flight (ToF) technique, which has been implemented on Timepix3 detector operated...
Abstract We examined the response of pixel detector Timepix3 with silicon sensor to well-defined fast neutron fields. Part was additionally equipped a mask distinct converter regions. The consists separate thermal and regions using 6 LiF hydrogen (plastic) converters, respectively. Measurements were performed mono-energetic neutrons produced at D-D D-T sources from Van de Graaff accelerator generator, Data collected low background including measurements moderator material provide thermalized...
We performed detailed measurements of the secondary cosmic ray field in lower atmosphere (at 200 m). use a miniaturised particle telescope consisting two closely stacked synchronised Timepix3 detectors. Position-, spectral-, and time-sensitive tracking provides enhanced particle-type resolving power high angular resolution mapping charged particles. Evaluation calibration directional response was with proton electron beams. The architecture, modeled developed data analysis provide accurate...
Abstract Monitoring and characterization of particle beams in wide-range is often necessary research many applications with accelerators. The quantitative measurement evaluation composition especially high-intensity are limited can become a challenge conventional methods simplified instrumentation for ease deployment. For this purpose, we developed novel technique based on high-resolution spectral-sensitive tracking single particles scattered from the beam path by thin foil. We use compact...
Abstract The semiconductor pixel detector Timepix2 is operated with highly integrated readout electronics as a miniaturized and portable MiniPIX TPX2 radiation camera for imaging spectral-sensitive particle tracking in wide field-of-view. device provides room-temperature operation, ease of use (single USB 2.0 port), online response single track visualization, fast frame (up to 60 fps) double per-pixel detailed measurements energy counting or timing sensitivity. We evaluate the applicability...
Abstract Silicon Carbide is a suitable semiconductor sensor for radiation measurement and nuclear applications. It has been recently implemented as position-sensitive imaging device coupled to the Timepix3 ASIC chip in form of miniaturized camera MiniPIX-Timepix3 SiC. In this work we systematically evaluate detection resolving power different species: electrons, fast neutrons, ions protons. Experimental calibrations were made at well-defined reference fields terms particle type, energy...
