Abstract Targeting a peak luminosity of 6 × 10 35 cm -2 s -1 , the Belle II experiment at SuperKEKB in Japan is considering an upgrade its interaction region. This involves vertex detector, which will be replaced by new fully pixelated detector (VTX). A monolithic CMOS pixel sensor named OBELIX (Optimized BELle pIXel) proposed to used VTX. Based on existing TJ-Monopix2 chip initially developed for ATLAS Inner Tracker (ITk) upgrade, designed 180 nm process with improved matrix and additional...
This article describes a custom VHDL firmware implementation of two-dimensional cluster-finder architecture for reconstructing hit positions in the new vertex pixel detector (VELO) that is part LHCb Upgrade. has been deployed to existing FPGA cards perform readout VELO, as further enhancement DAQ system, and will run real time during physics data taking, VELO hits coordinates on-the-fly at LHC collision rate. pre-processing allows first level software trigger accept 11% higher rate events,...
In cancer patients undergoing proton therapy, a very intense secondary radiation is produced during the treatment, which lasts around one minute. About billion prompt gamma-rays are emitted per second, and their detection with fast scintillation detectors useful for monitoring correct beam delivery. To cope expected count rate pile-up, as well scarce statistics due to short treatment duration, we developed an eidetic data acquisition system capable of continuously digitizing detector signal...
Abstract The LHCb detector has undergone a major upgrade for LHC Run 3. This Upgrade I facilitates operation at higher luminosity and utilises full-detector information the collision rate, critically including use of vertex information. A new locator system, VELO Upgrade, been constructed. core element are double-sided pixelated hybrid silicon modules which operate in vacuum close to beam high radiation environment. construction quality assurance tests these described this paper. incorporate...
This article describes the high-speed system designed to meet challenging requirements for readout of new pixel VErtex LOcator (VELO) upgraded LHCb experiment. All elements electronics chain will be renewed cope with requirement ~40-MHz full-event rate. The sensors equipped VeloPix ASICs and placed at ~5 mm from Large Hadron Collider (LHC) beams in a secondary vacuum tank an extremely high nonhomogeneous radiation environment. front-end (FE) highest occupancy have pixel-hit rates above ~900...
The electron amplification and transport within a photomultiplier tube (PMT) has been investigated by developing an in-house Monte Carlo simulation code. secondary emission in the dynodes is implemented via effective model Modified Vaughan's model, whereas computed with Boris leapfrog algorithm. PMT gain, rise time transit have studied as function of supply voltage external magnetostatic field. A good agreement experimental measurements using Hamamatsu R13408-100 was obtained. simulations...
The new LHCb Vertex Locator (VELO) for LHCb, comprising a pixel detector and readout electronics, will be installed in 2021 data taking Run 3 at the LHC. electronics centers around "VeloPix" ASIC front-end operating trigger-less 40MHz. A custom serializer, called gigabit wireline transmitter (GWT), associated protocol have been designed VeloPix. GWT are sent from serializers of VeloPix line rate 5.12 Gb/s, reaching total 2–3 Tb/s full VELO detector. Data over 300-m optic-fiber links to...
The Large Hadron Collider beauty (LHCb) detector is designed to detect decays of b- and c- hadrons for the study CP violation rare decays. At end LHC Run 2, many LHCb measurements remained statistically dominated. In order increase trigger yield purely hadronic channels, hardware will be removed, read out at 40 MHz. This, in combination with five-fold luminosity, requires radical changes LHCb's electronics, and, some cases, replacement entire sub-detectors state-of-the-art technologies....
