POLARIZED PROTON OPERATIONS IN THE AGS AND RHIC. Open
Polarized proton beam has been accelerated and stored at 100 GeV in Relativistic Heavy Ion Collider (RHIC) to study spin effects in the hadronic reactions. The essential equipment includes four Siberian snakes and eight spin rotators in tw…

RHIC pC CNI Polarimeter: Experimental Setup and Physics Results Open
Acceleration of polarized proton beams and experiments with them at RHIC require fast and reliable measurements of the polarization. The polarimeter presented here uses very high figure of merit of the elastic pC scattering at very low mom…

Measurement of the polarisation of a high energy muon beam Open
A muon beam polarimeter has been built for the SMC experiment at the CERN SPS, for muon energies of 100 to 200 GeV. The beam polarisation is determined from the energy spectrum of positrons from the decay μ+ → e+ νcνμ. A polarisation of − …

Measurement of the spin-dependent structure function g1(x) of the proton Open
We have measured the spin-dependent structure function $g_1~p$ of the proton in deep inelastic scattering of polarized muons off polarized protons, in the kinematic range $0.003<x<0.7$ and $1\\,\\mbox{GeV}~2<Q~2<60\\,\\mbox{GeV}~2$. Its fi…

Experiments on nucleon spin-dependent structure functions Open
In this presentation, the earlier measurements of the spin-dependent structure function of the proton in experiments at SLAC and at CERN are reviewed. In addition several new deep inelastic scattering experiments to measure the spin-depend…

Concept for an experiment on particle and jet production at midrapidity Open
The concept for an experiment to study global event signatures of quark Gluon Plasma formation and to investigate the propagation of jets through strongly interacting matter at high density is presented. Both event-by-event and inclusive m…
