Given the limited access to the ion source in the cyclotron as well the reduced number of beam diagnostics, an experimental facility was proposed for the commissioning of such ion source. The versatility of this test bench, which includes a movable puller, gives us the opportunity to validate and characterize the ion source behavior as well as to optimize the H⁻ production. In a first stage, the discharge characteristics of the ion source has been studied in the CIEMAT IST facilities.

	Funding: Work partially funded by CDTI and supported by the Spanish Ministry of Economy and Competitiveness, under project AMIT, within the subprogram CEN-20101014 The AMIT cyclotron will be a 8.5 MeV, 10 microAmp, CW, H⁻ accelerator for radioisotope production, including a superconducting, weak focusing, 4 T magnet, allowing for a low extraction radius and a compact design. The cavity is a 60 MHz, quarter wave resonator powered by a modular 8 kW solid state amplifier. The design of the cavity dealed with challenging requirements: high electric fields required by a high voltage (60 kV) on a small gap, a small aperture of the magnet leading to high capacitances and thermal losses and a requirement for a low overall size of the cavity. The fabrication process included high precision machining, soft soldering, laser welding and careful metrologies, which are described together with other technical and practical aspects. The low power tests showed a good agreement with the simulations. The conditioning of the cavity was performed with a 1.1 T magnetic field applied on the central region. It was successfully finished regarding to maximum voltage reached, power losses and temperatures. The cavity was also tested at high power with a constant hydrogen flow injected in the central region (as expected in the cyclotron) with success.

FRXBA1	Compact and Efficient Accelerators for Radioisotope Production	4824
	C. Oliver CIEMAT, Madrid, Spain
	The production in an efficient way of radioisotopes for medical use is crucial. With the closing in the next ten years of nuclear reactors the problem of the production of some of them is being critical. New approaches of producing these radioisotopes via accelerators are being developed. In the other hand a big effort is being made for making the accelerators for the production of radioisotopes more compact, efficient and with an optimized cost. This paper describes the recent advances in this kind of accelerator techniques.
