The response of n+p silicon strip sensors to electrons from a 90Sr source was measured using a multi-channel read-out system with 25 ns sampling time. The measurements were performed over a period of several weeks, during which the operating conditions were varied. The ...

Calorimeters with a high granularity are a fundamental requirement of the Particle Flow paradigm. This paper focuses on the prototype of a hadron calorimeter with analog readout, consisting of thirty-eight scintillator layers alternating with steel absorber planes. The ...

International audience; The FE-I4 is a new pixel readout integrated circuit designed to meet the requirements of ATLAS experiment upgrades. The first samples of the FE-I4 engineering run (called FE-I4A) delivered promising results in terms of the requested performances....

A new type of n-in-p planar pixel sensors have been developed at KEK/HPK in order to cope with the maximum particle fluence of 1-3×1016 1 MeV equivalent neutrons per square centimeter (neq/cm2) in the upcoming LHC upgrades. Four n-in-p devices were connected by bump-bon...
