	There are very strong demands for proton accelera-tors in medium energy range in recent years due to the fast growth of proton therapy and the space science in China. For the applications of proton therapy and pro-ton irradiation, the energy range of proton beam is usually from 200MeV to 250MeV, or even higher for astronavigation [1]. An R&D project for constructing a 230MeV superconducting cyclotron (CYCIAE-230) has been initiated at China Institute of Atomic Energy (CIAE) since Jan 2015. In July of 2016, after the fund-ing was approved by China National Nuclear Corpora-tion (CNNC), the construction project was fully launched. In Dec 2019, the superconducting main magnet and the RF system were transferred to the new-ly built commissioning site. Then, the RF commission-ing, ion source and central region test were performed even during the pandemic in early 2020. In September 2020, after finishing the commissioning tests of all subsystems, the beam was reached the extraction channel but with very low efficiency. Since then, with more efforts on beam diagnostics, the fine tuning of the beam phase and the adjusting of the superconduct-ing coil have been proven to be useful to get higher beam extraction efficiency ~55%. In this paper, the commissioning of the key components, including the main magnet, SC coils, internal ion source and central region, extraction system, etc, as well as the commis-sioning progress of the machine CYCIAE-230 will be presented.

	At the previous cyclotron conference an overview of the cyclotrons for radioisotopes production was shown. Here, we will focus on the development of IBA’s accelerators in the recent three years. Notably the Cyclone® 70, the Cyclone® 30XP and the Cyclone® Kiube have made progress. The expertise gained with the development of these machines has led IBA to develop a completely new cyclotron for 30 MeV protons, the Cyclone® IKON. As its first construction is ongoing, details on the design of this accelerator will be presented.

	In this paper, the design and installation CYCIAE-230 superconducting cyclotron main vacuum system’s equipment and the cryogenic systems based on the liquid helium zero-boiling-off technology for the CYCIAE-230 superconducting cyclotrons are described. The vacuum in the particle acceleration cavity is 2x10^-4 Pa. The main technical features of the accelerator vacuum system are that the main magnet cover plate with diameter 3.12m are used as a part of the main vacuum chamber, 8 magnetic poles, 8 high frequency resonators, and 2 sets of striper targets and 2 sets of radial targets are installed in the main vacuum chamber, resulting in technical difficulties such as large surface gas discharge, virtual leakage, high leakage of magnetic flux at the installation position of vacuum equipment (up to 2000 gauss) and so on. The main vacuum system is designed as 9 sets of TMP with magnet shields installed on the valley of magnet poles, which also used as RF cavity.

WEBI01	An Overview of the South African Isotope Facility (SAIF) Project	cyclotron, target, beam-transport, isotope-production	170
	I.L. Strydom iThemba LABS, Somerset West, South Africa
	The South African Isotope Facility (SAIF) is a new radioisotope production facility currently under construction at iThemba LABS in Cape Town and scheduled for completion in 2022. A commercial 70 MeV proton cyclotron from IBA with a number of beam lines equipped with isotope production stations, are being installed in retrofitted concrete vaults. The facility will be supported by new infrastructure and services which are being constructed. The completion of SAIF will greatly increase the radioisotope production capability of iThemba LABS, and enable the existing Separated Sector Cyclotron to be dedicated to nuclear research activities. An overview of the SAIF project from the inception phase through to the construction phase is provided here, discussing all related workstreams and progress made to date. A more detailed discussion of some specific systems is given, including the design of the isotope production stations, target handling system, and a new radioactive waste management facility.

	A 230 MeV superconducting AVF cyclotron SC230 is developed by Sumitomo Heavy Industries, Ltd. This is the world’s smallest isochronous cyclotron for proton therapy, and its weight is 65 tons, which is 0.3 times that of our previous cyclotron model. The size is reduced by generating high magnetic fields using NbTi supercon-ducting coils cooled without cryogen. In addition, this cyclotron features the maximum beam current >1 uA and low power consumption <200 kW. The beam-commissioning test started at the end of 2020, the first extracted beam was observed in July 2021, and the basic performance of the beam was measured. The processes and results of the beam commissioning are reported.

WEPO010	High Intensity Cyclotron System Integration and Commissioning for Industrialization Application	cyclotron, power-supply, controls, operation	225
	P.Z. Li, H.R. Cai, S.G. Hou, X.L. Jia, G.F. Pan, G.F. Song, J.F. Wang, G. Yang, H. Zhang, T.J. Zhang CIAE, Beijing, People’s Republic of China
	Up to 430 µA beam intensity was obtained in 10 MeV CRM cyclotron (CYCIAE-CRM) at China Institute of Atomic Energy (CIAE) in 2010. Whereafter, CIAE built a series of 14 MeV high intensity external ion source cyclotrons for medical isotope application and its relevant research. Compared with research cyclotron facility, cyclotron for industrialization application requires higher level of safety, usability and stability. Therefore, mechanical and electrical system integration and optimum are applied in the cyclotron design and commissioning. Electrical devices of cyclotron, including power supply, RF amplifier and PLC controller, are integrated into four standard industrial shielding cabinets with electromagnetic compatibility (EMC) design to improve electromagnetic interference and operation stability. Besides, earthing system is rearranged in regular laboratory maintenance period to minimize electromagnetic coupling of different signal systems. Based on the previous compact system integration, communication system is integrated into each electrical device as well and could be operated in local and remote mode for the convenience of commissioning. Industrial Ethernet standard PROFINET is adopted as communication protocol to improve the efficiency of protocol interaction towards millisecond level. Regarding RF system, start-up sequence of LLRF is optimized to increase uptime and reliability. The commissioning is also presented in this paper.

	J.-W. Kim, Y.H. Yeon IBS, Daejeon, Republic of Korea
	A 70 MeV H⁻ cyclotron system was installed at the Shindong campus of Institute for Basic Science from Nov. 2021. Installation was guided by precision survey so as to locate main components to their final positions. Electrical cables and utility lines were then connected and validation was followed for the control and safety systems. Internal beams were accelerated in May and utilized to isochronize the magnetic field by Smith-Garren method involving a series of magnetic shimming. A beam of 70 MeV was firstly extracted in July and two beam lines were commissioned for the beam energies of 40-70 MeV. Site acceptance tests were carried out with a temporary beam line installed to measure beam profiles at the location of ISOL target, Finally, a maximum beam power of 50 kW was successfully tested for six hours.
