	Pencil beam scanning (PBS) technology is a flexible and accurate dose delivery technology in proton therapy, which can deliver beams adapting to irregularly shaped tumors, while it requires precise diagnostic and real-time control of the beam dose and position. In this paper，a dose parameter acquisition and control system for the pencil beam scanning system based on the EPICS and LabVIEW is designed for HUST-PTF. The EPICS environment is built to realize the data exchange function between the front-end devices and control system. A channel access server（CAS）is designed to convert treatment parameters into the process variables (PVs) and expose them to the network for data sharing. Under current experimental conditions, the simulated beam current is generated according to the dose parameters in the treatment plan file. The current are processed by a digital electrometer and transmitted to the EPICS database in real time. Then the control system user interface based on LabVIEW is realized for displaying and parameter analysis.

	Funding: Work supported by the National Natural Science Foundation of China (Grant No.11505255, No.91026001) and the Fundamental Research Funds for the Chinese Central Universities(2015B29714) Arc discharge due to the electron emission is one of the key issues in the CW superconducting RF(SRF) for the CiADS particle accelerator. Arc discharges can deteriorate the SRF cavities and damage the facility. Monitoring arc discharges is important for the purpose of machine protection. In this paper, an arc discharge detector has been designed to provide fast response upon events of arc discharge using open-source hardware and LabVIEW software. Electronic design techniques are described to enhance the system stability while utilizing the flexibility of embedded electronics. The proposed detector system gives about 700 ns of response time and it employs a LabVIEW based graphic user interface. The system has the capability of detecting the instantaneous arc discharge events in real time. Timestamps of the event will be recorded to assist beam diagnostics. This paper describes the hardware/software implementation and concludes with initial results of tests at CiADS.

WEPB20	Experimental Setup of Apodization Techniques for Beam Diagnostics Performed at ELBE	experiment, electron, diagnostics, LabView	482
	B.G. Freeman, J. Gubeli, K. Jordan JLab, Newport News, Virginia, USA P.E. Evtushenko HZDR, Dresden, Germany
	The ELBE (Electron Linac for beams with high Brilliance and low Emittance) facility in Dresden, Germany is a multipurpose user facility, which is also used for accelerator R&D purposes. The beam line was set up for transverse beam profile measurements, where the imaging system includes a series of three apodizers and five circular apertures. During beam operations both of these were changed remotely through automated LabView routines. The bunch structure and charge were varied to collect a series of images that were acquired automatically, and then stored for later analysis. Over 12,000 images were captured and then analyzed using software written at Jefferson Lab that runs ImageJ as it’s main image processing library.

THOA01	Low vs High Level Programming for FPGA	FPGA, interface, operation, experiment	527
	J. Marjanovic DESY, Hamburg, Germany
	From their introduction in the eighties, Field-Programmable Gate Arrays (FPGAs) have grown in size and performance for several orders of magnitude. As the FPGA capabilities have grown, so have the designs. It seems that current tools and languages (VHDL and (System)Verilog) do not match the complexity required for advanced digital signal processing (DSP) systems usually found in experimental physics applications. In the last couple of years several commercial High-Level Synthesis (HLS) tools have emerged, providing a new method to implement FPGA designs, or at least some parts of it. By providing a higher level of abstraction, new tools offer a possibility to express algorithms in a way which is closer to the mathematical description. Such implementation is understood by a broader range of people, and thus minimizes the documentation and communication issues. Several examples of DSP algorithms relevant for beam instrumentation will be presented. Implementations of these algorithms with different HLS tools and traditional implementation in VHDL will be compared.
