Improvements to the RHIC Injection Kicker System
- Brookhaven National Laboratory (BNL), Upton, NY (United States). Relativistic Heavy Ion Collider (RHIC)
The RHIC Design Manual lists under "future improvements" the possibility of filling and operating the rings with a 120 bunch pattern, corresponding to 110 bunches after allowing for the abort gap. However the present performance of the injection kicker systems will require several modifications to achieve this goal. Operation with a 90- bunch pattern instead of the standard 60-bunch pattern is already achievable without hardware modifications. In this report changes which promise, but do not guarantee, 110 bunch operation are recommended. The major components of the RHIC injection system in each ring are the 4 kicker magnets, the thyratrons serving as switches, the thyratron trigger units, the Blumlein pulse forming coaxial tubes, and long coaxial cables between ring and power supply building. Beam measurements during the 2002 run showed a rise time of the injection systems in blue and yellow ring of 110 ns. Injection of 110 bunches was possible although with severe transverse emittance growth. Based on this experience, a system rise time of 95 ns would seem to be acceptable.
