The present work deals with obtaining neutron sensitive scintillation screens and their evaluation. We have used cerium doped garnet Gd1.2Y1.8Ga2.5Al2.5O12:Ce (GYAGG) as a scintillator since quaternary garnets with the optimized ratio of cations have demonstrated high light yield under γ-quanta and α-particles excitation, 50 000 ph/MeV and 12 000 ph/MeV respectively, with fast decay time (~50...
Solid-state sensors have been initially proposed as direct replacement of $^3He$ gas detectors but recently raise the interest in imaging systems.
We have developed a monolithic sensor with high spatial granularity in SOIPIX technology for the detection of alpha particles of energy compatible with the reaction products of neutrons with converter materials. The chipset is composed by the main...
By means of “Integrated Grid” InGrid MEMS technology, a MicroMegas is created on top of the (spark protected) TimePix-3 chip. Units containing four chips “Quads” and their services (data and control transfer, power, cooling) can be placed together, forming an arbitrarily large active direction area. Data from UV laser tracks, from cosmic ray muons, and from test beams are presented.

We present the latest performance studies of high-granularity resistive Micromegas (MM) detectors for tracking applications in high-rate environment. Nowadays MM are being used as tracking detectors in HEP experiment upgrades as in ATLAS experiment at LHC. To fulfill the requirements of stable and efficient operations up to particle fluxes as high as 10 MHz/cm2 coming from future High Energy...
