On present-day magnetic-confinement fusion experiments, the performance of multi-channel bolometer diagnostics has typically evolved over time through experience with earlier versions diagnostic and experimental results obtained. For future large-scale experiments reactors, it is necessary to be able predict as a function design decisions constraints. A methodology been developed accuracy which volume-integrated total radiated power can estimated from measurements by resistive diagnostic,...
Pixelated LGADs have been established as the baseline technology for timing detectors High Granularity Timing Detector (HGTD) and Endcap Layer (ETL) of ATLAS CMS experiments, respectively. The drawback segmenting an LGAD is non-gain area present between pixels consequent reduction in fill factor. To overcome this issue, inverse (iLGAD) has proposed by IMB-CNM to enhance factor provide excellent tracking capabilities. In work, we explore use iLGAD sensors surface damage irradiation developing...
The high-luminosity upgrade of the ATLAS and CMS experiments includes dedicated sub-detectors to perform time-stamping minimum ionizing particles (MIPs). These detectors will be exposed up fluences in range 1.5–2.5×1015neq/cm2 require a time resolution per detecting layer 30 ps, for non-irradiated sensors, 50–70 ps (depending on fluences) sensors at end their lifetime. To cope with these requirements, low-gain avalanche diode (LGAD) has been chosen as baseline detection technology. In this...
Silicon sensors are the go-to technology for high-precision in particle physics. But only recently low-noise silicon with internal amplification became available. The so-called Low Gain Avalanche Detector (LGAD) have been developed applications High Energy Physics, but lack two characteristics needed measurement of low-energy protons (<60 keV): a thin entrance window (in order tens nm) and efficient signals created near sensor's surface depth below 1 um). In this paper we present proton...
In this work, we present the pLGAD concept, which is based on LGAD technology developed at IMB-CNM. We describe main characteristics of novel detector suitable for low energy particles detection.

In this contribution, we will present the status of technological developments at IMB-CNM to fabricate Inverse Low Gain Avalanche Detectors (iLGAD) for pixelated detectors. This iLGAD sensor concept is one most promising technologies enabling future 4D tracking paradigm that requires both precise position and timing resolution. concept, based on LGAD technology, readout done ohmic contacts, allowing a continuous unsegmented multiplication junction. architecture provides uniform gain over all...
