In the past few years, there has been considerable interest in using an energy recovery linac (ERL) for future light sources and high-energy nuclear physics. The electron beam requirements of the ERLs under consideration span a wide range in parameters such as current, current density, frequency, operating temperatures, accelerating gradients etc. The design of the injector, whether it is normal conducting or superconducting, DC or RF, average current, temporal profile of the electron bunch all play key role in the choice of the photocathode. In this paper, we attempt to provide an overview of the available cathode materials, the pros and cons associated with each and the electron beam parameters they can provide.

The DEMO R&D activities are intended to support the design activities of fusion demonstration reactor (DEMO) in the Broader Approach (BA). Recent progress in the DEMO R&D activities, particularly the status and plan for EU/JA collaboration activities, is presented in this conference. Equipment for investigation of the erosion /corrosion behavior of SiC/SiC composites in Pb-$$^{17}$$Li is under fabrication for installation and experiments at the Rokkasho site. Irradiation of reduced activation ferritic /martensitic steels (EUROFER and F82H) in a Belgian reactor, BR2, is being prepared. Exchange of RAFM, neutron multiplier and tritium breeder samples between EU and JA is planned for collaborative characterization. Thus, the R&D activities are being upgraded.

The Broader Approach (BA) activities have started in mid 2007. The DEMO R&D activities are intended to support the BA activities for design of fusion demonstration reactor (DEMO). The progress so far in the DEMO R&D activities is presented in this conference. Based on the common interest of the EU and Japan towards DEMO, current activities are smoothly proceeding in the following five areas: (1) SiC/SiC composites, (2) Tritium technology, (3) Materials engineering for DEMO blanket, (4) Advanced neutron multiplier, and (5) Advanced tritium breeders. From 2010 these R&D activities will be accelerated, after the preparation of the experimental equipment and facilities is completed.
