	Low-level radio frequency (LLRF) control systems based on µTCA standard have been developed for facilities such as compact energy recovery linac (cERL) and superconducting test facility (STF) at the High Energy Accelerator Research Organization (KEK), Japan. Three different types of boards were developed according to their different applications. Experimental physics and industrial control system (EPICS) was selected as the data communication system for all of these µTCA boards. The LLRF systems showed good performance during the beam commissioning. This paper presents the current status of the µTCA-based LLRF systems in the cERL and STF.

THP19	Timing System for Multiple Accelerator Rings at KEK e⁺/e⁻ Injector LINAC	timing, injection, gun, laser	207

	The KEK e⁺/e⁻ injector linac is operated in multiple modes that can be switched every 20 ms for e⁺/e⁻ beam injection to five different accelerator rings, SuperKEKB High Energy Ring (HER), Photon Factory (PF) ring, PF-AR, positron damping ring (DR) and SuperKEKB Low Energy Ring (LER). The MRF event system which consists of event generators (EVG) and event receivers (EVR) is used to distribute event codes that correspond to beam modes and data buffer. The EVR generates various trigger timing signals depending on the event code. The data buffer incudes some important parameters such as HER/PDR injection RF bucket, setting currents of pulsed quad/steering magnets that enables multiple beam injection. The event system uses the linac main clock (114.2 MHz) which synchronized to HER/LER, but due to PF and PF-AR rings are not synchronized to the linac, an additional synchronization system is employed for those rings. We will describe the timing and synchronization system to fulfill multiple injections to independent rings and report status of the system.
