Use of Plastic Detectors to Confirm the Acceleration of Argon Nuclei to Relativistic Velocities at the Princeton Particle Accelerator

摘要

Argon ions were recently accelerated to 11.7 GeV at the Princeton Particle Accelerator. This represents a two-fold increase in the mass over particles previously accelerated to relativistic energies. The report describes how a stack of cellulose nitrate track detectors was used to confirm the successful acceleration with the unambiguous identification of 79 argon tracks within a clearly defined 1 1/4-inch-beam spot.
