Test-beam results of a silicon pixel detector with Time-over-Threshold read-out having ultra-precise time resolution

A time-tagging hybrid silicon pixel detector developed for beam tracking in the NA62 experiment has been tested in a dedicated test-beam at CERN with 10 GeV/c hadrons. Measurements include time resolution, detection efficiency and charge sharing between pixels, as well as effects due to bias voltage variations. A time resolution of less than 150 ps has been measured with a 200 μm thick silicon sensor, using an on-pixel amplifier-discriminator and an end-of-column DLL-based time-to-digital converter

TRAPPISTe pixel sensor with 2 µm SOI technology

Tracking for particle physics instrumentation in SOI technology (TRAPPISTe-1) is an R&D project to study the feasibility of manufacturing a monolithic active pixel sensor (MAPS) in silicon on insulator (SOI) technology. The first prototype of this series of sensors has been designed with a 2 μm SOI CMOS technology available in UCL, Louvain-la-Neuve. Simulations are presented for this prototype. Leakage measurements have been done on a photovoltaic cell, manufactured in the same process on a low-resistivity substrate. As a next step, a high-resistivity demonstrator will be designed

The beam and detector of the NA62 experiment at CERN

NA62 is a fixed-target experiment at the CERN SPS dedicated to measurements of rare kaon decays. Such measurements, like the branching fraction of the K(+) → π(+) ν bar nu decay, have the potential to bring significant insights into new physics processes when comparison is made with precise theoretical predictions. For this purpose, innovative techniques have been developed, in particular, in the domain of low-mass tracking devices. Detector construction spanned several years from 2009 to 2014. The collaboration started detector commissioning in 2014 and will collect data until the end of 2018. The beam line and detector components are described together with their early performance obtained from 2014 and 2015 data.NA62 is a fixed-target experiment at the CERN SPS dedicated to measurements of rare kaon decays.
