GeSn as next-generation material for short-wave infrared single-photon detection

Andrea Giunto

In recent years, the automotive industry has aspired to bring self-driving vehicles to the generalpublic and light detection and ranging (LiDAR) sensors have emerged as the preferred solution forcar vision systems. At present, LiDAR technologies employ exp ...

Electron flux and pressure dynamic in the LHC vacuum pilot sector as a function of beam parameters and beam pipe properties

Ambrogio Fasoli, Elena Buratin, Vincent Baglin

The Large Hadron Collider (LHC) is affected by the electron cloud (EC) phenomenon that can provoke beam instabilities, detrimental heat loads and pressure increases in the vacuum system. An innovative dedicated system called vacuum pilot sector (VPS) provi ...

The theoretical temporal resolution limit tT of a silicon photodiode (Si PD) is 11.1 ps. We call “super temporal resolution” the temporal resolution that is shorter than that limit. To achieve this resolution, Germanium is selected as a candidate material ...

Accurate Profile Measurement of the low Intensity Secondary Beams in the CERN Experimental Areas

Inaki Ortega Ruiz

The CERN accelerators deliver a wide spectrum of secondary beams to the Experimental Areas. These beams are composed of hadrons, leptons, and heavy ions that can vary greatly in momentum (1 GeV/c to 400 GeV/c) and intensity (10^2 to 10^8 particles per seco ...

Development of the scintillating fibre tracker technology for the LHCb upgrade and the LHC beam profile monitoring system

Olivier Göran Girard

The LHCb detector located at the large hadron collider (LHC) at CERN will undergo a major upgrade in 2019-2020. The detector will be prepared to operate at an increased instantaneous luminosity and to read out full events at 40MHz. This requires many chang ...

Here we report another surprising feature of the methylammonium metal halide material family, the phototunability of the diode response of a heterojunction made of CH3NH3PbI3 and its close relative, CH3NH3SnI3. In the dark state the device behaves as a dio ...

Amer Chemical Soc2017

The TORCH detector is being developed for low-momentum particle identification, combining time-of-flight and Cherenkov techniques to achieve charged particle pi/K/p separation up to 10 GeV/c over a flight distance of 10m. This requires a timing resolution ...

CMOS-Compatible PureGaB Ge-on-Si APD Pixel Arrays

Edoardo Charbon, Mahdi Aminian

Pure gallium and pure boron (PureGaB) Ge-on-Si photodiodes were fabricated in a CMOS compatible process and operated in linear and avalanche mode. Three different pixel geometries with very different area-to-perimeter ratios were investigated in linear arr ...

A dynamic operation of a PIN photodiode

Alexander Tagantsev, Maher Kayal, Adil Koukab, Serguei Okhonin, Maxim Gureev, Alexander Kvasov, Marc Pastre, Denis Sallin

Traditionally, photodiodes operate at static reverse bias, and incident light intensity is obtained from the relatively week photocurrent. In this paper, we introduce a different concept of photodiode function: the photodiode is used in a dynamic regime wh ...
