We present test results of the hybridized Timespot1 ASIC, developed for 4D-tracking in high luminosity LHC experiments. The ASIC reads a 32x32 pixel matrix bump-bonded on a 3D-type trenched electrode silicon sensor, which already demonstrated intrinsic timing performance and high radiation hardness at test beams, achieving temporal resolutions close to 10 ps. The ASIC is developed in CMOS...
The High Luminosity upgrade of the LHC machine aims at an increase of peak luminosity and to possibly reach an integrated luminosity of $3000-4500\;$fb$^{-1}$. Consequently, the CMS experiment is called for an upgrade to keep up with the new challenges such as unprecedented radiation environment, requiring high resilience, and increased number of events per bunch crossing, requiring higher...
A dedicated 16-channel board was designed for matrix test and inter-pixel proprieties. Each channel is composed of a dual stage amplifier design with an uniform response up to a frequency range of 8 GHz. A single SiGe transistor configuration is used for both stages, with the first acting as a transimpedance amplifier and the second as a voltage amplification stage. The design features a...
Monolithic CMOS pixel sensors (or MAPS) offer a particularly advantageous balance between pixel granularity, hit rate and power dissipation, making them attractive devices for vertexing and tracking. Existing reticule-size sensors [1, 2, 3] display power ranging roughly from 35 to 100 mW/cm2 for corresponding hit rates in the range 10 to 100 MHz/cm2 and timestamping capabilities from 5 µs down...
This work describes the development of a 64-channel ASIC implemented in a commercial 65 nm CMOS technology. The electronics is designed to readout a camera plane composed by a matrix of Silicon Photo-Multipliers (SiPMs) where a current signal is induced by Extensive Airshowers (EASs). Latters are generated by Ultra-High Energy Cosmic Rays (UHECRs) and Cosmic Neutrinos (CNs) through Cherenkov...
The semiconductor industry is currently adopting SiC as a replacement for silicon in power devices. Compared to Si, SiC offers several advantages which make it an attractive detector material. Among them is the higher displacement energy as compared to silicon, which makes SiC potentially more radiation hard. The very low leakage currents do not increase even for highly irradiated samples....
X-ray color imaging is a promising method that provides extra information due to photon energy binning. Due to the high demand for high spatial resolution, the detectors tend to decrease the pixel pitch size. The decreasing pixel pitch size directly affects the spectral resolution due to the charge-sharing effect and fluorescent photons that travel elsewhere in the sensor material. Therefore,...
