SCK CEN, the Belgian Nuclear Research Centre, in partnership with IBA s.a., Ion Beam Applications, is designing an ADS prototype, MYRRHA, and is conducting an associated R&D programme. The project focuses primarily on research on structural materials, nuclear fuel, liquid metals and associated aspects, on subcritical reactor physics and subsequently on(More)
During the last few years, IBA started the development of an accelerator-based BNCT system. The accelerator is a Dynamitron built by RDI in USA and will produce a 20 mA proton beam at 2.8 MeV. Neutrons will be produced by the (7)Li(p,n)(7)Be nuclear reaction using a thin lithium target. The neutron energy spectrum will be tailored using a beam shaping(More)
Proton therapy offers several advantages compared with classical radiotherapy owing to a better dose conformity to the tumour volume. However, proton interactions with beam transport elements and the human tissues lead to the production of secondary neutrons, resulting in an extra whole-body dose with some carcinogenic potential. In this study, the(More)
The science and technology of proton and carbon therapy was initially developed in national and university laboratories. The first hospital based proton therapy facility was built at Loma Linda University with the help from Fermilab. After this initial phase, and starting with the tender for the proton therapy system at MGH, many proton and carbon beam(More)
At the beginning of 1994, the Massachusetts General Hospital (MGH) of the Harvard Medical School in Boston (MA, USA) a pioneer in proton therapy since 1959, selected a team led by Ion Beam Applications SA (IBA) to supply the proton therapy equipment of its new Northeast Proton Therapy Centre (NPTC). The IBA integrated system includes a compact 235 MeV(More)
Most of the nuclear reactors used today for radioisotope production (mainly 99Mo for nuclear medicine), research and industrial applications, are due, in the next years, for a major refurbishment or for decommissioning. This problem has prompted a renewed interest on alternative neutron production methods. In particular, the need for reliable sources of Mo(More)
The C70 cyclotron accelerates ions with q/m = 1 (H−) as well as q/m = 1/2 (D−, He, H 2 ). The beam is injected axially and bent onto the median plane with a spiral inflector. An electrostatic deflector placed at the exit of the spiral inflector, is used for centering both types of particles. An ECR ion source produces the He and H 2 particles; a multicusp(More)
SCK•CEN in partnership with IBA S.A. is designing a multi-purpose ADS for R&D applications – MYRRHA – and is conducting an associated R&D programme. In a first stage, the project focuses mainly on demonstration of the ADS concept and safety research on sub-critical systems. In a later stage, the device will also be dedicated to research on structural(More)
High current cyclotrons are needed for the production of radioisotopes for nuclear medicine or for radiotherapy. Another application of high current cyclotrons is the production of 99mTc, either directly or as a fission product in a cyclotron-driven subcritical neutron source. The first cyclotrons for radioisotope production were classical, positive ions(More)
