In the 2012 RHIC heavy ion run, we col­lided 96.4~GeV U-U ions and 100~GeV Cu-Au ions for the first time in RHIC. The new pre-in­jec­tor with the elec­tron-beam ion source (EBIS) was used to pro­vide ions for RHIC ion col­li­sions for the first time. By adding the hor­i­zon­tal cool­ing, the pow­er­ful 3-D sto­chas­tic cool­ing largely en­hanced the lu­mi­nos­ity. With the dou­ble bunch merg­ing in the Booster and AGS, the bunch in­ten­si­ties of Cu and Au ions in RHIC sur­passed their pro­jec­tions. Both PHENIX and STAR de­tec­tors reached their in­te­grated lu­mi­nos­ity goals for the U-U and Cu-Au col­li­sions. In this ar­ti­cle we re­view the ma­chine im­prove­ment and per­for­mance in this run.

The R&D ERL pro­ject at BNL aims to demon­strate a high charge, high cur­rent en­ergy re­cov­ery linac. One of the key SRF sys­tem is the 704 MHz half-cell SRF gun. The SRF gun is de­signed to de­liver up to 0.5 A beam at 2 MeV with 1 MW of CW RF power. The gun com­mis­sion­ing started in No­vem­ber 2012. The first pho­toe­mis­sion beam from the SRF gun is ex­pected in early 2013. This pre­sen­ta­tion will dis­cuss the re­sults of the SRF gun com­mis­sion­ing, and the per­for­mance of the high-power RF sys­tem.
