	GUI for supervision, control and data acquisition systems are usually oriented to specialist users. In big organizations like CERN, where different teams play the roles of operators, scientists and instrumentation specialists, providing a unique or static user interface usually results in a situation of dissatisfaction of everyone. On the other hand, providing distinct user interfaces for each type of user increases the development and maintenance effort and makes software evolution heavier. The approach taken for the design and development of GUIs for radiation and environment protection at CERN addressed this issue by integrating user interface changes as an embedded software functionality. Key users were provided with a tool to build, deploy and maintain their own tailor-made user interfaces, in a graphical way and without the necessity of learning any kind of programming or scripting languages. Other benefits observed from this solution include reduction of the resources spent on the support and maintenance and increase of the frequency of GUIs updates, executed without compromising the underlying control system. This paper describe the innovative design that was implemented.

THP05	Development and Current Status of KURAMA-II	survey, monitoring, detector, operation	170
	M. Tanigaki Kyoto University, Research Reactor Institute, Osaka, Japan
	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.

THP06	Reliability Improvement for the Insertion Device Control in the TPS	controls, EPICS, insertion, insertion-device	173
	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.

FRCC2	Continuous Beam Scanning Intensity Control of a Medical Proton Accelerator Using a Simulink Generated FPGA Gain Scheduled Controller	controls, proton, power-supply, cyclotron	242

	At the Centre for Proton Therapy at the Paul Scherrer Institut we treat cancer patients using a fixed beam line and two gantries. The latter use a step-and-shoot technique to deliver dose covering the treatment volume with a grid of weighted proton bunches. Dose delivery for tumours moving under respiration (e.g. lung) is however challenging and not routinely performed because of the interplay between target and beam motions. At the Gantry 2 unit, we are implementing a novel continuous beam modulation concept called line scanning, aiming at realizing a faster dose delivery to allow for effective organ motion mitigation techniques such as rescanning and gating. The current should stabilise within 100 us, which is tough due to the non-linearity of the system and latency of the monitors. In this work we implemented a gain scheduled controller and a predictor by modelling the accelerator in Simulink and developing a controller using the frequency domain robust method. We used Mathwork’s HDL Coder functionality to generate VHDL code that was implemented in an FPGA in the gantry control system. Latency, overshoot and dosimetric performance improved considerably compared to a classic PID.

	The CERN Health, Safety and Environment Unit is mandated to provide a Radiation and Environment Supervision, Control and Data Acquisition system for all CERN accelerators, experiments as well as the environment. The operation and maintenance of the previous CERN radiation and environment supervisory systems showed some limitations in terms of flexibility and scalability.

REMUS design and development focused on these desired features. REMUS interfaces with 75 device types, providing about 3,000 measurement channels (approximately 600, 000 tags) at the time of writing. This paper describes the architecture of the system, as well as the innovative design that was adopted in order to face the challenges of heterogeneous equipment interfacing, diversity of end users and continuous operation.
