MO3BCO03	Control System Development at the South African Isotope Facility	160
	J.K. Abraham, H. Anderson iThemba LABS, Somerset West, South Africa W. Duckitt Stellenbosch University, Matieland, South Africa
	The South African Isotope Facility (SAIF) at iThemba LABS is well into its commissioning phase. The intention of SAIF is to free up our existing Separated Sector Cyclotron to do more physics research and to increase our radioisotope production and research capacity. An EPICS based control system, primarily utilising EtherCAT hardware, has been developed that spans the control of beamline equipment, target handling and bombardment stations, vault clearance and ARMS systems. Various building and peripheral services like cooling water and gases, HVAC and UPS have also been integrated into the control system via Modbus and OPCUA to allow for seamless control and monitoring. An overview of the SAIF facility and the EPICS based control system is presented. The control strategies, hardware and various EPICS and web based software and tools utilised are presented.

MO3BCO05	Online Models for X-ray Beamlines Using Sirepo-Bluesky	165

	Funding: This material is based upon work supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Science, under Award Number DE-SC0020593. Synchrotron radiation beamlines transport X-rays from the electron beam source to the experimental sample. Precise alignment of the beamline optics is required to achieve adequate beam properties at the sample. This process is often done manually and can be quite time consuming. Further, we would like to know the properties at the sample in order to provide metadata for X-ray experiments. Diagnostics may provide some of this information but important properties may remain unmeasured. In order to solve both of these problems, we are developing tools to create fast online models (also known as digital twins). For this purpose, we are creating reduced models that fit into a hierarchy of X-ray models of varying degrees of complexity and runtime. These are implemented within a software framework called Sirepo-Bluesky* that allows for the computation of the model from within a Bluesky session which may control a real beamline. This work is done in collaboration with NSLS-II. We present the status of the software development and beamline measurements including results from the TES beamline. Finally, we present an outlook for continuing this work and applying it to more beamlines at NSLS-II and other synchrotron facilities around the world. *https://github.com/NSLS-II/sirepo-bluesky

	Funding: This work is supported by the National Magnetic Confinement Fusion Science Program (No. 2017YFE0301803) and by the National Natural Science Foundation of China (No.51821005). Large experimental facilities are essential for pushing the frontier of fundamental research. The control system is the key for smooth operation for Large experimental facilities. Recently many new types of facilities have emerged, especially in fusion community, new machines with completely different designs are being built. They are not as mature as accelerators. They need flexible control systems to accommodate frequent changes in hardware and experiment workflow. The ability to quickly integrate new device and sub-systems into the control system as well as to easily adopt new operation modes are important requirements for the control system. Here we present a control system framework that is built with standard web technology. The key is using HTTP RESTful web API as the fundamental protocol for maximum interoperability. This enables it to be integrated into the already well developed ecosystem of web technology. Many existing tools can be integrated with no or little development. for instance, InfluxDB can be used as the archiver, Node-RED can be used as the Scripter and Docker can be used for quick deployment. It has also made integration of in house developed embedded devices much easier. In this paper we will present the capability of this control system framework, as well as a control system for field-reversed configuration fusion experiment facility implemented with it.

MO3BCO07	Fast Beam Delivery for Flash Irradiations at the HZB Cyclotron	178
	J. Bundesmann, A. Denker, G. Kourkafas HZB, Berlin, Germany J. Heufelder, A. Weber Charite, Berlin, Germany P. Mühldorfer BHT, Berlin, Germany
	In the context of radiotherapy, Flash irradiations mean the delivery of high dose rates of more than 40 Gy/s, in a short time of less than one second. The expectation of the radio-oncologists are lesser side effects while maintaining the tumour control when using Flash. Clinically acceptable deviations of the applied dose to the described dose are less than 3%. Our accelerator control system is well suited for the standard treatment of ocular melanomas with irradiaton times of 30 s to 60 s. However, it is too slow for the short times required in Flash. Thus, a dedicated beam delivery control system has been developed, permitting irradiation times down to 7 ms with a maximal dose variation of less than 3%.
