A very high momentum particle identification detector

Particle Identification with the Rich Detector

The RICH detector in the hyperon beam experiment WA89 at the CERN-SPS is used for identiication of , K and p=p out of ?-N reactions. Methods for reduction of charged particle background in the detector are discussed. An algorithm for particle identiication was developed and tested on a sample of ! p decays. A separation of p and with 90% eeciency and a rejection by a factor of 10 or more at a m...

Light-particle Emission at High Angular Momentum

Microfabricated high-throughput electronic particle detector.

We describe the design, fabrication, and use of a radio frequency reflectometer integrated with a microfluidic system, applied to the very high-throughput measurement of micron-scale particles, passing in a microfluidic channel through the sensor region. The device operates as a microfabricated Coulter counter [U.S. Patent No. 2656508 (1953)], similar to a design we have described previously, b...

A Water Tank Čerenkov Detector for Very High Energy Astroparticles

Extensive airshower detection is an important issue in current astrophysics endeavours. Surface arrays detectors are a common practice since they are easy to handle and have a 100% duty cycle. In this work we present an experimental study of the parameters relevant to the design of a water Čerenkov detector for high energy airshowers. This detector is conceived as part of the surface array of t...

Towards a high performance geometry library for particle-detector simulations

Thread-parallelisation and single-instruction multiple data (SIMD) ”vectorisation” of software components in HEP computing has become a necessity to fully benefit from current and future computing hardware. In this context, the Geant-Vector/GPU simulation project aims to re-engineer current software for the simulation of the passage of particles through detectors in order to increase the overal...
