METU-Defocusing Beam Line (METU-DBL) Project has been started in August 2015 and aims to construct a beam line at Turkish Atomic Energy Authority Sarayköy Nuclear Education and Research Center Proton Accelerator Facility to perform Single Event Effect (SEE) tests for the first time in Turkey. The METU-DBL is 8m-long and has quadrupole magnets to enlarge the beam size and collimators to reduce the flux. [...]

Overview and Status of the MedAustron Ion Therapy Center Accelerator / Pivi, Mauro (MedAustron, Wr. Neustad) ; De Franco, Andrea ; Farinon, Fabio (MedAustron, Wr. Neustad) ; Kronberger, Matthias (MedAustron, Wr. Neustad) ; Kulenkampff, Tobias (CERN) ; Kurfürst, Christoph (MedAustron, Wr. Neustad) ; Myalski, Szymon (MedAustron, Wr. Neustad) ; Nowak, Sebastian (MedAustron, Wr. Neustad) ; Osmić, Fadmar (MedAustron, Wr. Neustad) ; Penescu, Liviu (Abstract Landscapes, Montpellier) et al.
The synchrotron-based MedAustron accelerator in Wiener Neustadt, Austria, has seen the first clinical beam and has been certified as a medical accelerator in December 2016. This represented a major milestone for the facility whose original design originated more than a decade ago and construction started four years ago. [...]

Progress in the Bunch-to-Bucket Transfer Implementation for FAIR / Ferrand, Thibault (Darmstadt, Tech. Hochsch.) ; Bachmann, Oliver (Darmstadt, Tech. U.) ; Bai, Jiaoni (Darmstadt, GSI) ; Damerau, Heiko (CERN) ; Klingbeil, Harald (Darmstadt, Tech. Hochsch. ; Darmstadt, GSI)
The transfer of bunched ion beams between various synchrotrons is required for the multi-accelerator complex FAIR, presently under construction at GSI. To avoid a dedicated distribution infrastructure for radiofrequency (RF) signals between each source and destination synchrotron, a new approach has been developed to transmit bunch and bucket phase information using synchronous Ethernet.

Space-Charge Compensation in the Transition Area Between LEBT and RFQ / Schneider, Philipp (AEG Forschungsinst., Frankfurt) ; Born, Daniel (AEG Forschungsinst., Frankfurt) ; Britten, Virginia (AEG Forschungsinst., Frankfurt) ; Droba, Martin (AEG Forschungsinst., Frankfurt) ; Meusel, Oliver (AEG Forschungsinst., Frankfurt) ; Noll, Daniel (CERN) ; Podlech, Holger (AEG Forschungsinst., Frankfurt) ; Schempp, Alwin (AEG Forschungsinst., Frankfurt)
The transition from a space charge compensated beam in the LEBT to an uncompensated beam in the RFQ will influence the beam parameters. To investigate the impact of the electric fields on the space charge compensation, an insulated cone is used as a repeller electrode in front of the RFQ. [...]

The PSB Operational Scenario with Longitudinal Painting Injection in the Post-LIU Era / Forte, Vincenzo (CERN) ; Albright, Simon (CERN) ; Angoletta, Maria Elena (CERN) ; Baudrenghien, Philippe (CERN) ; Benedetto, Elena (CERN) ; Blas, Alfred (CERN) ; Bracco, Chiara (CERN) ; Carli, Christian (CERN) ; Findlay, Alan (CERN) ; Garoby, Roland (CERN) et al.
Longitudinal painting has been presented as an elegant technique to fill the longitudinal phase space at injection to the CERN PSB once it is connected with the new Linac4. Painting brings several advantages related to a more controlled longitudinal filamentation, lower peak line density and beating reduction, resulting in a smaller space-charge tune spread. [...]

Optimisation of a High-Resolution, Low-Latency Stripline Beam Position Monitor System for Use in Intra-Train Feedback / Blaskovic Kraljevic, Neven (JAI, UK) ; Bett, Douglas (CERN) ; Bodenstein, Ryan (JAI, UK) ; Bromwich, Talitha (JAI, UK) ; Burrows, Philip (JAI, UK) ; Christian, Glenn (JAI, UK) ; Perry, Colin (JAI, UK) ; Ramjiawan, Rebecca (JAI, UK)
A high-resolution, low-latency beam position monitor (BPM) system has been developed for use in feedback systems at particle accelerators and beamlines that operate with trains of particle bunches with bunch separations as low as several tens of nanoseconds, such as future linear electron-positron colliders and free-electron lasers. The system was tested with electron beams in the extraction line of the Accelerator Test Facility at the High Energy Accelerator Research Organization (KEK) in Japan. [...]

The ISOLDE facility at CERN produces radioactive isotopes far from stability for fundamental nuclear physics research. The radioactive beams are accelerated to high-energy using a post-accelerator before being transferred for study in different experiments at the end of a network of High Energy Beam Transfer (HEBT) lines.

Commissioning of the Stripping Foil Units for the Upgrade of the PSB H⁻ Injection System / Bracco, Chiara (CERN) ; Burger, Stephane (CERN) ; Forte, Vincenzo (CERN) ; Goddard, Brennan (CERN) ; Guidoboni, Greta (CERN) ; Jorat, Louise Olivia (CERN) ; Mikulec, Bettina (CERN) ; Navarro Fernandez, Araceli (CERN) ; Noulibos, Remy (CERN) ; Roncarolo, Federico (CERN) et al.
The PSB will be extensively upgraded during the next long shutdown of the CERN accelerator complex, to double the brightness of the stored beams. The existing multi-turn injection will be replaced by a charge exchange system designed for the 160 MeV hydrogen ions provided by Linac4. [...]
