Abstract: Current methods of measuring polarization of particle
beams at high energies have small analyzing powers and large systematic
errors. A potentially better method using pn -> np charge exchange
may reduce systematic errors. Eventually designed to be run at the new
Relativistic Heavy Ion Collider (RHIC), the proposed method would use a
solid carbon target. Monte Carlo methods were used to examine the effects
of a carbon target on the measurement of beam polarization. A calorimeter
design was proposed for detect neutrons at small angles. An initial
prototype has been tested by detecting Cerenkov radiation caused by cosmic
ray muons. Results of these tests and neutron simulations by GEANT suggest
a possible design for a neutron calorimeter.
