A polarized 
He target system was built and used for JLab experiments
E94-010 and E95-001. Several approved experiments will use the
polarized He target system this summer and in the future.
The polarized He target is based on
the principle of spin exchange between optically pumped Rubidium vapor and
He gas. Several high power (30 Watts) 795 nm diode lasers will be used
for the optical pumping. A laser hut has been built and installed in Hall A.
This LSOP describes the setup of the
laser system in the laser hut and at the target area,
details the potential
hazards associated with the operation of this setup and provides instructions
for the safe and effective use of the equipment. In addition,
this manual provides information about the functioning of the various safety
systems installed to protect personnel and equipment.
