The 2024 Run in the Injectors

Abstract

The injectors provided polarized protons to RHIC for most of Run 24. That was followed by 3 weeks of Gold at 9.8 GeV/n using Tandem. Physics with PP was first declared on May 1 st and the PP portion of the run ended on Sept. 30 th . The standard BU4/AU4 setup was used for most of it. Although, from Sept. 7 th to 30 th the AGS skew quad setup (BU4/AU6) was used instead. More work was done on the Split/Merge setup (BU3/AU3) initially developed in Run 22. A two Linac pulse setup was also developed this run (BU4/AU2). As far as PP work in the injectors goes this note will focus on the standard, Split/Merge, and Two Linac pulse setups. The 9.8 GeV/n Tandem Au setup was essentially the same as in Run 23. The injector setup for Helium-3 from EBIS (BU7/AU7), which was used for an APEX study in RHIC on August 7 th , will be covered as well.
