DEVELOPMENT OF A POLARIZED ~3He ION SOURCE FOR RHIC

摘要

A polarized ~3He ion source is under development for use at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. The gas will be polarized using metastability exchange optical pumping, then transferred into the electron beam ion source for ionization. Nuclear polarization of the order of 70％ is expected under optimal conditions, and roughly 10~(11) doubly-ionized ~3He~++ ions will be created in each 20 μs pulse.
