  Several groups internationally have been designing and building adjustable permanent magnet based quad-rupoles for light sources, colliders, and plasma accelera-tors because of their very high gradients and zero power consumption. There are now examples of widely adjusta-ble PM dipoles too. The ZEPTO project, based at STFC Daresbury Laboratory, developed several highly adjusta-ble PM-based dipole and quadrupole prototypes for CLIC, and is now building a quadrupole to be installed in Diamond to gain experience ahead of the Diamond-2 upgrade. This is a review and comparison of the recent designs globally with comments on the future prospects.

  One of the new paradigms in radiation therapy (RT) is the FLASH dose delivery irradiation technique. The FLASH methodology consists in delivering millisecond pulses of radiation (total beam-on time < 100-500 ms) delivered at a high mean dose-rate (> 40-100 Gy/s) and pulse amplitude (> 1E6 Gy/s), over 2000 times faster than in conventional RT. New accelerator ideas are under development or are being tested to deliver this type of beam. In this paper we will report the accelerator technology used for the pre-clinical studies and the necessary developments to deliver this novel dose RT technique.

  The MEDICIS facility is a unique facility located at CERN dedicated to the production of non-conventional radionuclides for research and development in imaging, diagnostics and radiation therapy. It exploits in a Class A work sector, a dedicated isotope separator beam line, a target irradiation station at the 1.4 GeV Proton Synchroton Booster (PSB) and receives activated targets from external institutes during CERN Long Shut-Downs. The target is heated up at high temperatures to allow for the diffusion and effusion of the atoms out of the target that are subsequently ionized. The ions are accelerated and sent through an off-line mass separator. The radionuclide of interest is extracted through mass separation and implanted into a thin metallic collection foil. After collection, the batch is prepared to be dispatched to a research center. In the near-future, the radiochemistry process will also be performed in MEDICIS. Since its commissioning in December 2017, the facility has provided novel radionuclides such as Tb-149, Tb-155, Tm-165, Er-169 and Yb-175 with high specific activity, some for the first time, to European research institutes part of the collaboration.

Project seeks to tackle the shipping industry’s most pressing problem, its large-scale emissions of SOx, NO and PM, by developing a hybrid exhaust gas-cleaning technology that combines an EB accelerator with improved wet-scrubbing technology. It is unique - in a single technological system - addresses all three types of emissions simultaneously. It promises to be cheaper and more efficient than existing solutions. There are two main stages involved: 1) SO2 and NOx oxidation during irradiation of wet gases by the EB from the accelerator and 2) the pollution products absorption into aqueous solution. For the very first time, test trials in the real maritime environment where conducted and attracted interest of maritime industry, policy makers and accelerator community. Proof-of-Concept clearly confirmed potential of this accelerator technology and formed basis for the full-scale project where this hybrid system will be applied to the sea-going ferry on the regular traffic. Considering that this project is of highest relevance to the accelerator community at large, we will be happy to present it and disseminate its promising results along with the related unfolding activities.
