The APS booster injector is a 7-GeV electron synchrotron. Several improvements have been implemented in the booster area, including the development of the 92-nm low emittance lattice, upgrading the ramp current readback ADC, and development of a new firing card for the main ramp supplies. Recently we have completed the commissioning of the low emittance lattice and it is now APS operational lattice. Combined with improvement in the optimization in the storage ring lattice and injection, we have achieved close to 100% storage ring injection efficiency. This report presents the improvements and measured beam parameters and the measured performance of the ramp control.
