The Partial Snake Experiment At The Ags Progress Report 15 August 1992 14 August 1994

In the two year funding period from August 15, 1992--August 14, 1994, the authors progresses can be summarized as follows: (1) the solenoidal partial snake was installed in the AGS synchrotron in May, 1993 and was subsequently successfully tested; (2) the internal polarimeter for the AGS was assembled, tested and installed in the AGS; (3) the 200 MeV polarimeter at the LINAC was tested; (4) the AGS polarized ion source was renovated; (5) the first phase of the polarized beam experiments was successfully accomplished in April 1--8, 1994, of polarized proton acceleration up to G{sub {gamma}} (almost equal to) 20; (6) they are currently renovating tune jump quadrupoles in order to accelerate polarized proton up to 25 GeV/c. The full test of these experiments will be in 1995. During this funding period, the principal investigator has spent about 20% of his research time on this project, which includes the design and manufacturing of the solenoid partial snake, beam dynamics issues of the AGS with the 5% solenoid partial snake and spin dynamics of synchrotrons with snakes in general. The graduate student, Mr. H. Huang has spent 100% of his research time working on spin dynamics. The graduate student is currently staying at BNL for the E880 experiment preparation.
