Microchannel plates are vacuum-based electron multipliers for particle—in particular, photon— detection, with applications ranging from image intensifiers to single-photon detectors. Their key strengths large signal amplification, active area, micrometric spatial resolution and picosecond temporal resolution. Here, we present the first microchannel plate made of hydrogenated amorphous silicon (a-Si:H) instead lead glass. The breakthrough lies in possibility realizing silicon-based (AMCPs) on...
We perform simulations for future Cherenkov Telescope Array (CTA) observations of RX~J1713.7$-$3946, a young supernova remnant (SNR) and one the brightest sources ever discovered in very-high-energy (VHE) gamma rays. Special attention is paid to explore possible spatial (anti-)correlations rays with emission at other wavelengths, particular X-rays CO/H{\sc i} emission. present series simulated images RX J1713.7$-$3946 CTA based on set observationally motivated models gamma-ray In these...
The Gamma Cherenkov Telescope (GCT) is proposed to be part of the Small Size (SST) array Array (CTA). GCT dual-mirror optical design allows use a compact camera diameter roughly 0.4 m. curved focal plane equipped with 2048 pixels ~0.2° angular size, resulting in field view ~9°. designed record flashes light from electromagnetic cascades, which last only few tens nanoseconds. Modules based on custom ASICs provide required fast electronics, facilitating sampling and digitisation as well first...
Abstract The Linear IFMIF Prototype Accelerator (LIPAc) is designed to accelerate 125mA of deuteron beam 9MeV in continuous wave (CW). superconductive RF Linac has not yet been installed and the final accelerating stage now under commissioning RFQ. This system developed by INFN (Italy) before installation QST (Japan). RFQ longest World with its 9.8m requires power injection from 8 independent synchronized coupler ports. LIPAc demonstrated acceleration at 5MeV for 1ms a 1s repetition period...
Abstract The Linear IFMIF Prototype Accelerator, LIPAc, is being commissioned aiming at validating the RFQ up to 5 MeV beam acceleration. Eventually, nominal of MeV–125 mA in 1 ms length and Hz rate pulsed mode was achieved 2019. operation has been resumed since July 2023 after a long maintenance including recovery from unexpected problems RFQ-RF system. This new phase aims commissioning full configuration except SRF LINAC, which replaced by temporary transport line. Focusing on behavior, it...

Thin-film-on-ASIC (TFA) detectors are monolithic pixel devices that consist of amorphous silicon detecting diodes directly deposited on readout electronics. This paper presents a characterization the TFA spatial resolution using electron-beam-induced current (EBIC) technique, in which pads patterned microstrips were swept by beam. We measured for different configurations and thicknesses active layer with beam energies, currents sweep speeds. observed generated electron-hole pairs collected...
We investigate the use of time-resolved differential reflectivity for study ultrafast and recombination dynamics resonantly excited quantum-well excitons. illustrate technique with extensive measurements using femtosecond laser pulses on a 4-nm ${\mathrm{In}}_{0.1}{\mathrm{Ga}}_{0.9}\mathrm{As}|\mathrm{GaAs}$ quantum well. Simple considerations applicable to systems allow us relate generic change in transition oscillator strength, which turn is proportional exciton density (population...
