	The Vulcan Neodymium-Glass High-Power Laser Facility at the Central Laser Facility in the UK has been operational for over 40 years providing a world-leading and high-profile service to International researchers in the field of Plasma Physics. Over that time the Facility has had many modifications and enhancements to the buildings, the laser hardware and to the computerised control, synchronisation and timing systems. As the laser systems have developed and the user experiments have continued to become much more complex and demanding, many new operational conditions have been required. The use of four independent laser oscillators with different properties - including temporal, spectral and operating frequencies - have meant that the optical and electrical multiplexing and the timing and synchronisation systems have all had to be adapted and extended to cope with these additional needs. However, these changes have resulted in the build-up of the overall system jitter to ± 250 ps between long (ns) and short (ps) optical pulses and this is a limiting factor for time-critical experiments. This paper will present some of the key changes and improvements that have recently been made.

	H. Jin, Y. Choi, S. Lee IBS, Daejeon, Republic of Korea
	For the RAON accelerator that transport beams with high energy and power, a machine protection system (MPS) that protects each device from sudden beam loss is necessary. For this reason, we have been preparing for the development of the MPS with the start of the RAON accelerator construction. For effective MPS operation and stable accelerator operation, we divided the MPS into four subsystems: fast protection system, slow interlock system, run permit system, and post-mortem system. Among them, the FPGA-based fast protection system and the PLC-based slow interlock system have been tested by prototypes and are currently working on the mass production. The run permit system and the post-mortem system are also undergoing basic design and software development. In this paper, we will describe the progress of the MPS development through detailed hardware and software development in the RAON accelerator and explain the future plans.

	KURAMA-II, a successor of a carborne gamma-ray survey system named KURAMA (Kyoto University RAdiation MApping system), has been developed and applied to various activities related to the nuclear accident at TEPCO Fukushima Daiichi Nuclear Power Plant in 2011. KURMA-II has established its position as an effective method for the radiation monitoring method in environment on a long-term basis. The development of KURAMA-II is still on the way to extend its application areas such as the trial to port the system to a single-board computer or the development of cloud services of data management for the users who don’t have capabilities to manage the data processing system. In this paper, the current status of KURAMA-II on its developments and applications along with some results from its applications are introduced.

	C.Y. Wu, J. Chen, Y.-S. Cheng, K.T. Hsu, K.H. Hu, C.Y. Liao NSRRC, Hsinchu, Taiwan
	Insertion devices (ID) are essential components in third-generation synchrotron light sources, which can produce highly-brilliant, collimated and quasi-monochromatic radiation over a broad energy range for experiments. Reliable operation of the insertion devices is important to users of beamlines. The most unpredictable fault is due to a soft error in optical absolute encoders due to radiation. There are several solutions to avoid such faults, e.g. by increasing the distance of the encoder from the beam, by a lead shield cover and finally by adopting an auxiliary position sensing devices to help recovery from a fault. Efforts to improve operational reliability of the TPS ID controls will be discussed.

THPI7	Long-term Stability Observed by Electron BPM and Photon BPM for Taiwan Photon Source

	P.C. Chiu, K.T. Hsu, K.H. Hu, C.H. Huang NSRRC, Hsinchu, Taiwan
	TPS is 3-GeV synchrotron light source which have opened for public users since September 2016 and now offers 400 mA top-up mode operation. The requirements of the long term orbit stability and orbit reproducibility after beam trip have been gradually more and more stringent and become a challenge from users’ request. Furthermore, the thermal effect would be expected to be worsen after 500 mA top-up operation which should deteriorate the orbit drift. The report investigates the long-term orbit stability observed from eBPM and XBPM and also evaluates the possibility of the local XBPM feedback.

THPI8	Design and Implementation of Stepper Motor Control of the LINAC High Power RF System Based on FPGA
THP08	use link to access more material from this paper's primary paper code
	R. Rujanakraikarn, Ch. Dhammatong, W. Phacheerak SLRI, Nakhon Ratchasima, Thailand
	In this paper, the new motion control system that governs the position of high power attenuators and phase shifters in the linac’s RF system at SLRI is described. The drive system, which was originally driven by a set of AC reversible motors, is replaced by a new set of stepper motors. The hardware selection and installation is presented in detail. The digital control circuits are designed in VHDL and implemented on a commercial Field Programmable Gate Array (FPGA) board. The main software part, implemented in MicroBlaze Microcontroller System (MCS), is coded in C to control the position of stepper motors relative to the DC voltage reference points of the hardware system. A LabVIEW GUI is designed to interface with the control system to provide reference points and display position values via RS-232 and PLC interfaces. This stepper motor control system can be used to effectively implement the phase and amplitude control system of the linac’s RF signals in the future.
