Design, construction, and commissioning of the Exit Charge Detector for BNL-AGS Experiment 896

[摘要] The Exit Charge Detector (ECD) is used to determine the impact parameter of relativistic gold-gold interactions in BNL-AGS Experiment 896 by measuring the total charge of projectile-like particles in each collision. Results are presented from simulations which optimized the ECD's dimensions. The ECD was then constructed, and the hardware and the construction techniques used are described. Analyses of data from the operation of the ECD in heavy-ion collisions are discussed. These analyses indicated a significant amount of correlated noise in the experiment. A method to correct for this noise offline is discussed. Also, significant probabilities for the interaction of the beam with materials other than the target are investigated. Finally, plans to improve the detector for the coming Spring 1998 $msp{197}Au$ run are discussed.
