A cylindrical Half-Wave length Resonator is a proved superconducting structure In the low energy part of accelerators. Accelerating efficiency in such resonator is limited by the peak RF magnetic field on the inner cavity surface. By an enlargement of the dome cavity volume containing RF magnetic field the cavity peak surface magnetic field is reduced. Additionally, this results in the power dissipation reduction. The paper reports results of cavity shape optimization and structural analysis of conical Half-Wave Resonators for β=v/c=0.11 and two resonance frequencies 325 MHz and 162.5 MHz. This Work is supported by the DOE SBIR Program, contract #DE-SC0006302.

In the framework of the International Fusion Materials Irradiation Facility (IFMIF), which consists of two high power CW accelerator drivers, each delivering a 125 mA deuteron beam at 40 MeV, an accelerator prototype is presently under design for the first phase of the project. A superconducting option has been chosen for the 5 MeV RF Linac, based on a cryomodule composed of 8 low-beta Half Wave Resonators, 8 Solenoid Packages and 8 RF couplers. This presentation will mainly focus on the HWR development: realization and vertical tests of the two HWR prototypes will be presented, including the validation tests of the innovating cold tuning system, located in the central region of the cavity (results with tuning system are expected for the conference). In addition, the 1st cryomodule current design will be also discussed.
