✦ Synopsis


Within the HIPPI (high intensity pulsed proton injector) project, supported by the 6th PCRD (framework programme for research and development) of the European Union, the German research centre Forschungszentrum Ju ¨lich proposed a multi-spoke H-cavity for the intermediate energy section (b = 0.5) of high power proton linear accelerators. The IPN Orsay is associated with FZ Ju ¨lich for the prototype design, and before that, all preliminary mechanical studies.

A triple-spoke superconducting cavity has a more complicated geometry, compared to the same beta elliptical cavity. As a consequence the design requires some sophisticated tools, like the CAD (computer aided design) code CATIA. In addition, in order to solve the specific mechanical problems imposed by external constraints, a sophisticated mechanical simulation tool CAST3M (Calcul et Analyse de Structure et Thermique par la me ´thode des Ele ´ments Finis) is used [H.
