Task 1: Coordination and dissemination of R&D for ISOL facilities

Neutron converters

Converters which produce neutrons from initial charged-particle beams are an essential component of high-power ISOL facilities. Solid converters are in use at ISOLDE and being developed at GANIL for SPIRAL2, while an innovative liquid Hg converter will be an essential component (developed at IPUL, ISOLDE and PSI) of the future EURISOL facility.

Development of fission and other target materials; study of release properties

The improvement of radiation hardness and release properties of ISOL targets is essential to increase the beam intensities and scientific output of ISOL facilities. Vigorous related R&D, particularly concerning sub-micron structured target materials, will be performed at ALTO and ISOLDE, linked with JRA02-ActILab

Improvement of ion-source performances

Efficiency and selectivity are the essential parameters to be improved, as well as multi-charge capability for 1+ to n+ acceleration schemes. Cutting-edge technologies for various types of ion sources are being developed, some of them within JRA01-ARES

• Laser ion Sources (IN2P3-ALTO, ISOLDE)
• ECR Sources (GANIL, INFN-LNS, JYFL)
• EBIS Sources (ISOLDE)
• Febiad source (IN2P3-ALTO)

Beam manipulation and purification

Progress in this very challenging subject is essential for providing high-quality beams to the users. Major progress is expected in coolers and mass separators (INFN-LNS, ISOLDE) and gas cells and traps (JYFL), in coordination with JRA03-PREMAS.

Superconducting Linear Accelerator Technology

Advances in RFQ systems and superconducting accelerator cavities are necessary for the realisation of the HIE-ISOLDE and SPIRAL2 projects and later for EURISOL. This work will be progressing at GANIL, INFN-LNL, IN2P3-IPNO and ISOLDE.
