Silicon sensors with high time resolution can help particle identification in the International Linear Collider (ILC). We are studying Low Gain Avalanche Diodes (LGADs) as a high timing resolution sensor. As a step to develop LGADs, we are now focusing to characterize Avalanche Photo Diode (APD)s, because the APDs has the same multiplication structure as LGADs. We studied the characteristics of APDs with particles from radioisotopes.
Several future high-energy physics facilities are currently being planned. The proposed projects include high energy $e^+ e^-$ circular and linear colliders, hadron colliders and muon colliders, while the Electron-Ion Collider (EIC) has already been
The tracking system of the CMS experiment, currently under construction at the Large Hadron Collider (LHC) at CERN (Geneva, Switzerland), will include a silicon pixel detector providing three spacial measurements in its final configuration for tracks
We describe a setup for optical quality assurance of silicon microstrip sensors. Pattern recognition algorithms were developed to analyze microscopic scans of the sensors for defects. It is shown that the software has a recognition and classification
The timing performance of silicon sensors bump-bonded to Timepix3 ASICs is investigated, prior to and after different types of irradiation up to $8 times 10^{15} 1 mathrm{,Mekern -0.1em V} mathrm{ ,n_{eq}} {mathrm{ ,cm}}^{-2}$. The sensors have been
In this paper we discuss the measurement of charge collection in irradiated silicon pixel sensors and the comparison with a detailed simulation. The simulation implements a model of radiation damage by including two defect levels with opposite charge
