	The Photo Injector Test Facility at DESY in Zeuthen (PITZ) was built to test and to optimize sources of high brightness electron beams for Free-Electron Lasers (FELs). In order to achieve high accelerating gradients and long RF pulse lengths in the RF gun cavities an extensive and safe RF conditioning is required. A State Machine based Automatic Conditioning application (SMAC) was developed to automate the RF conditioning processes, allowing for greater efficiency and performance optimization. SMAC is written in Java and uses State Chart XML (SCXML) as the finite-state machine execution environment based on Harel statecharts. It employs the Distributed Object-Oriented Control System (DOOCS) and Three-fold Integrated Networking Environment (TINE) for the communication with the control system of PITZ. The graphical user interface (GUI) is created by using the Java Swing toolkit. Communication between GUI and SXML processing layer is performed via Document Object Model (DOM) events. The SMAC application has been successfully applied to RF conditioning of several gun cavities at PITZ.

THP19	Timing System for Multiple Accelerator Rings at KEK e⁺/e⁻ Injector LINAC	linac, timing, injection, 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.
