Radiation damage effects at High Luminosity LHC (HL-LHC) expected fluences at the outer tracker layers greater than $1ร10^{15}$ $n/cm^2$ 1 MeV equivalent, as well as total ionising doses on the order of 70 Mrad, will impose very stringent constraints in terms of radiation resistance of solid-state detectors, from both silicon substrate and silicon oxide.

The nuclear disaster at the Fukushima Daiichi Nuclear Power Plant (NPP) in Okuma, Fukushima, was initiated primarily by the tsunami following the Tohoku earthquake on March 11, 2011. After a large amount of radioactive substances was released into the environment of the region, the distribution of the radiation sources on the ground was monitored. However, there have been only few estimations...

Knowing the reliability of electronic systems operating under extreme conditions is crucial, especially in nuclear and space applications. In such environment, the proper functionality of electronic systems is endangered because of Single Event Effect (SEE) occurrence. In our work, we present an experimental setup for measuring fault detection correlated with events occuring in silicon...

Monolithic silicon pixel sensors combine the electronics and sensing layer in one silicon element and are produced in commercial CMOS processing lines without the need for a fine pitch interconnection technology as used for hybrid silicon pixel detectors. This reduces the overall cost, but also the complexity of the module assembly procedure. The sensors can be thinned to typical thicknesses...

During the Long Shutdown 3 (LS3) of the Large Hadron Collider (LHC), around 2024-2026, significant parts of the CMS detector will be upgraded to allow an efficient data taking during the subsequent High Luminosity LHC phase (HL-LHC). The HL-LHC will have a factor 5 higher instantaneous luminosity - resulting in a factor 5 higher event "pileup", and a factor 10 increase in integrated luminosity...

The ATLAS upgrade programme for the high-luminosity large hadron collider (HL-LHC) includes the replacement of the inner tracking detector with an all-silicon system. The outer layers of the new tracker consist of strip sensors and the inner region is made up of pixel sensors. The harsh radiation environment requires the pixel system to run at low temperature to minimise damage to the silicon...

In preparation for the High luminosity LHC (HL-LHC) upgrade, the whole ATLAS inner tracker will be replaced by a new silicon detector tracker. The innermost region will be covered by silicon pixel detectors as a high density of produced particles is expected. In order to operate in such an environment, high-resolution sensor and high-speed readout system is required. At the moment the RD53A,...

Solar neutron observations are important on understanding of nucleon acceleration mechanism in the Sun. However, previous ground-based observations with large area telescopes (โผ10 m$^2$ ) at high latitude are not sensitive to solar neutrons due to attenuation in the earth atmosphere (roughly 10 detection since its discovery in 1980). From space, the SEDA-AP instrument with much smaller area...

In the soft gamma ray region (100 keV-10 MeV), Compton scattering is the dominant physical process, and It is an unexplored region where observation has not progressed because the background is rather high compared to the signal from celestial sources. In this region, the direction and energy of incident gamma rays can be determined by using Compton camera technique where photons are Compton...

Microbeam radiotherapy is a novel type of radiotherapy in which narrow beams of radiation (typically less than 500 ยตm) are spatially fractionated, delivering a non-uniform distribution to the target tumour volume. Due to the very high dose gradients involved, new dosimetric techniques are required for translation into clinical practise. Current real-time beam monitoring is typically performed...
