Sections 1 through 6 of this report give parameters for low-energy gold ions circulating in RHIC at injection and in AGS at extraction. Section 7 gives parameters for Au79+ ions circulating in RHIC at the standard injection magnetic rigidity of 81.11378003 Tm. Section 8 gives parameters for medium-energy Au79+ ions circulating in RHIC at 31.2 GeV per nucleon. The standard parameters for gold ions circulating in Booster, AGS, and RHIC are documented in. For convenience they are listed here in Sections 9 through 11. Gold ions normally come from EBIS but can be provided by Tandem if EBIS is down for maintenance or repairs. Section 12 gives parameters for Tandem Au31+ ions circulating in Booster. In order to achieve a single bunch of Tandem ions at Booster extraction, a 6 to 3 to 1 bunch merge is required. This has been developed by Keith Zeno and is documented in. Different bunch merges and ll patterns in AGS are used depending on the desired bunch intensity in RHIC and the desired number of bunches to be injected into RHIC per AGS cycle. These are illustrated in Sections 13 through 17. The standard bunch merges done in Booster and AGS are documented in. Bucket and bunch parameters for clean injection of low-energy gold ions into RHIC are documented in. Parameters of past medium and low energy gold ion setups are documented in.
