	Particle accelerators are thrusting the exploration of beam production towards several demanding territories, that is beam high intensity, high energy, short time and geometry precision or small size. Accelerators have thus more and more stringent characteristics that need to be measured. Beam diagnostics accompany these trends with a diversity of capacities and technologies that can encompass compactness, radiation hardness, low beam perturbation, or fast response and have a crucial role in the validation of the various operation phases. Their developments also call for specialized knowledge, expertise and technical resources. A snapshot from the French CNRS/IN2P3 beam instrumentation network is proposed. It aims to promote exchanges between the experts and facilitate the realization of project within the field. The network and several beam diagnostic technologies will be exposed. It includes developments of system with low beam interaction characteristics such as PEPITES, fast response detector such as the diamond-based by DIAMMONI, highly dedicated BPM for GANIL-SPIRAL2, emittance-meters which deals with high intensity beams and development for MYRRHA, SPIRAL2-DESIR and NEWGAIN.

TUP07	Efficient Heavy Ion Acceleration with High Brilliance	rfq, brilliance, cavity, operation	83
	C. Zhang GSI, Darmstadt, Germany H. Podlech IAP, Frankfurt am Main, Germany
	It is challenging to realize an efficient and brilliant RFQ for accelerating high current heavy ion beams, as space charge effects are most pronounced at the low energy end. Here ’efficient’ means an as short as pos-sible accelerating structure with minimum RF power consumption, while ’brilliant’ means high beam transmission and low emittance growth. Using the > 9 m long HSI RFQ accelerator, one of the longest RFQs in the world, as an example, a promising solution has been presented.

	H. Podlech IAP, Frankfurt am Main, Germany H. Höltermann, H. Hähnel, B. Koubek, U. Ratzinger BEVATECH, Frankfurt, Germany
	A new linac for the NICA ion collider is under con-struction for JINR at BEVATECH GmbH. As first cavity the 2.5 m long RFQ was manufactured. Within this length it accelerates particles with a mass to charge ratio up to three to an energy of 600 keV/u. The operation frequency is 162.5 MHz and the 4-Rod structure consists of 23 RF cells that need to be adjusted using tuning blocks in order to provide the required field distribution along the electrodes. The status of the manufacturing and the upcoming tuning process including the overall RF setup of the RFQ are summarized in this paper.

The cyclotron C70XP is an accelerator built for the production of non-conventional radionuclides for nuclear medicine, research in physics, radio-chemistry and biology. Its injection section has been designed for 4 types of ions (HH⁺, D-, He2+ & H⁻), 3 types of ions reach the end of the beamline (H⁺, He2+ & D⁺) at the maximum energy of 70 MeV (H⁻ & He2+). It is important that regular and standard runs provide similar beam features with a good emittance quality. An investigation, focused on the beam in the injection, cover beam measurements and potential beam geometry constraints. The beam transverse characteristics in the injection line has been studied with an Allison-type emittance meter and a simple instrumented collimator installed inside the injection line . With these 2 devices, it is scrutinized how the beam emittance evolves as a function of settings of the injection magnets and the source parameters . Dependencies found between the emittance, beam hotspots and tunings are discussed, as well as the protection performed by the collimator. Future of this work with a potential collimator design is introduced. F.Poirier and al., ’The Injection and Chopper-Based System at Arronax C70XP Cyclotron’ **F.
