	With the termination of the neutron and proton therapy programs at iThemba LABS, the use of the Separated Sector Cyclotron (SSC) has now shifted to nuclear physics research with both stable and radioactive ion beams, as well as biomedical research. A dedicated isotope production facility with a commercial 70 MeV H-minus cyclotron has been approved and both the cyclotron and isotope production target stations will be housed in the vaults that were previously used for the therapy programs. The status of this new facility will be reported. In the future the SSC will mostly be used for nuclear physics research, as well as the production of isotopes that cannot be produced with the 70 MeV H-minus cyclotron. At present the production of the alpha-emitting radionuclide Astatine (211At) with a 28 MeV alpha beam is being investigated. Progress with the construction of a facility for production of radioactive beams will be discussed. There will also be reports on development work on the ECR ion sources and progress with implementation of an EPICS control system.

TUP004	Integration of EtherCAT Hardware Into the EPICS Based Distributed Control System at iThemba LABS	152
	J.K. Abraham, W. Duckitt iThemba LABS, Somerset West, South Africa
	iThemba Laboratory for Accelerator Based Sciences (iThemba LABS) has, over the past 30 years, carried out several upgrades to its control electronics and software. This culminated in the adoption of EPICS as the de-facto distributed control system at the lab. In order to meet the changing technology and user requirements, iThemba LABS adopted EtherCAT as its new industrial communication standard. Building on an open EtherCAT master implementation and prior community development, iThemba LABS has successfully integrated a variety of EtherCAT hardware into its EPICS control system. This paper presents the open source software toolchain that has been developed and is used at iThemba LABS and showcases several hardware installations at the facility and abroad. Community involvement and future plans for this initiative are also presented.

TUP007	Operational Experience in the Treatment of Ocular Melanomas with a New Digital Low-level RF Control System	162
	T. Fanselow, J. Bundesmann, A. Denker, U. Hiller HZB, Berlin, Germany J.K. Abraham, J.L. Conradie, W. Duckitt iThemba LABS, Somerset West, South Africa
	Ocular melanomas have been treated for the last 20 years at the Helmholtz-Zentrum Berlin in collaboration with the Charité Universitätsmedizin Berlin. However, parts of the initial control system electronics date back to the 1970s, when the machine was installed. Facing a critical shortage of legacy and obsolete components and with the down-time due to failures in the electronics on the increase, a decision was made to install the digital low-level RF control system, developed by iThemba LABS, on our K=132 cyclotron. A short description of the installation and commissioning process, which occurred in April 2017, and the experiences of the first 2 years of operation with the new digital low-level RF control system is presented.

THA03	React Automation Studio: A New Face to Control Large Scientific Equipment	285
	W. Duckitt, J.K. Abraham iThemba LABS, Somerset West, South Africa
	A new software platform to enable the control of large scientific equipment through EPICS has been designed. The system implements a modern tool chain with a React frontend and a PyEpics backend as a progressive web application. This enables efficient and responsive cross platform and cross device operation. A general overview of React Automation Studio as well as the system architecture, implementation at iThemba LABs, community involvement and future plans for the system is presented.
