The ring imaging Čerenkov detector for the BRAHMS Experiment at RHIC

چکیده
A ring-imaging Čerenkov counter, to be read out by four 100channel PMT’s, is a key element of the BRAHMS Experiment. We report here the most recent results obtained with a prototype tested at the BNL AGS using several radiator gases, including the heavy fluorocarbon C4F10 . Ring radii were measured for different particles (π−, μ−, e−) for momenta ranging from 2 to 12 GeV/c employing pure C4F10 as radiator.

TheBRAHMSRing Imaging Čerenkov Detector
A Ring Imaging Čerenkov detector built for the BRAHMS experiment at the Brookhaven RHIC is described. This detector has a high index of refraction gas radiator. Čerenkov light is focused on a photo-multiplier based photon detector with a large spherical mirror. The combination of momentum and ring radius measurement provides particle identification from 2.5 GeV/c up to 35 GeV/c for pions and ka...

The BRAHMS experiment at RHIC has the capability to measure the transverese spin asymmetries in polarized pp induced pion production at RHIC. The first results from a short run show a signaificant asymmetry for π + and π − at moderate x F. The trend of the data is in agreement with lower energy data while the absolute value are surprisingly large.
متن کاملCharged Particle Production at High Rapidity in p+p Collisions at RHIC
This report describes the recent analysis of identified charged particle production at high rapidity performed on data collected from p+p collisions at RHIC ( √ s = 200GeV). The extracted invariant cross-sections compare well to NLO pQCD calculations. However, a puzzling high yield of protons at high rapidity and pT has been found. INTRODUCTION The p+p system is used in many cases as a paradigm...
