Polarized hydrogen gas target. Closeout report

PDF Version Also Available for Download.

Description

The purpose of the equipment was to produce a polarized gas target for use as an internal target in storage rings. The part funded under this grant was the construction of the atomic-beam apparatus. In addition to the $300,000 award, $13,267 from DOE operating funds and $19,700 provided by the University was spent on the construction of the atomic beam apparatus. Certain other parts required for the experiments, like the target cell, the target vacuum chamber, and the detectors, were funded by the University of Wisconsin. The cost for installation of the target in the cooler ring at the Indiana ... continued below

Description

The purpose of the equipment was to produce a polarized gas target for use as an internal target in storage rings. The part funded under this grant was the construction of the atomic-beam apparatus. In addition to the $300,000 award, $13,267 from DOE operating funds and $19,700 provided by the University was spent on the construction of the atomic beam apparatus. Certain other parts required for the experiments, like the target cell, the target vacuum chamber, and the detectors, were funded by the University of Wisconsin. The cost for installation of the target in the cooler ring at the Indiana University Cyclotron Facility was $2,400. The equipment became operational for the first time in August 1992, after the sixpole magnets, the delivery of which was delayed by more than 6 months because of manufacturing problems, were delivered. There followed a period of measurements to optimize the atomic-beam intensity. In 1992, further work was done using other sources of funds to augment the performance of the polarized gas target by means of radiofrequency (RF) transitions intended to double the degree of polarization of the target. Immediately after the above tests, the polarized gas target equipment was shipped to Bloomington, Indiana where installation in the proton storage ring was completed in July 1993.
