1. ELiTES European Community - Japan Scientist exchange program

2. What is ELiTES ELiTES: ET-LCGT interferometric Telescope Exchange of Scientists Grant for collaboration on cryogenic developments between KAGRA and ET European 7th Framework Program Marie Curie (2012-2016) European Europeans visit Japan to collaborate on KAGRA Japaneses visit Europe to collaborate on ET Lifetime 4 years

3. Participants M. Beker, M. Blom, H.J. Bulten, M. Colombini, A. Conte, R. P. Croce, R. De Salvo, V. Galdi, L. Glielmo, E. Hennes, G. Hofmann, L. Iannelli, N. Kimura, J. Komma, K. Kuroda, H. Lück, E. Majorana, P. Murray, L. Naticchioni, R. Nawrodt, V. Pierro, I. M. Pinto, M. Principe, M. Punturo, P. Puppo, P. Rapagnani, S. Reid, F. Ricci, S. Rowan, P. Seidel, T. Sekiguchi, T. Suzuki, R. Takahashi, M. Thürk, T. Uchiyama, J.F.J. van den Brand, F. Vasca

4. ELiTES consists of four Working Packages WP1: Cryogenic payload (E. Majorana) WP2: Cryogenic mirror (R. Nawrodt) WP3: Cooling system (K. Somiya) WP4: Organization (M. Punturo) Initiative web page: http://www.et-gw.eu/descriptionelites

5. Teleconference every month General meeting (3rd-4th Oct.) in Tokyo general meeting Web page: http://www.et-gw.eu/1stelitesgeneralmeeting

6. Concrete Example of ELiTES activity Development of alternative cryogenic suspensions Tentative breakdown: Attenuation performance evaluation – KAGRA Cryogenic performance evaluation – KAGRA Finite Element Modelling – NIKHEF-Glasgow Silicon flexure prototyping – NIKHEF Silicon blade prototyping – NIKHEF – Roma U. Sapphire wires and mirror attachment Ultra-sound Machining – Schiller University - Jena WP1 and WP2

7. Based on common interests Development of alternative cryogenic suspensions: Necessary for KAGRA Necessary for Low Frequency interferometer in ET (Einstein Telescope) Xylophone

8. Aim of the sub-project: Aggressively develop cryogenic suspensions From the present strawman design to the level of a conceptual design and maybe to a preliminary design over the four year lifetime of the agreement

9. Other activity example Pulse tube cryocooler development Share measurements of vibration performance Share techniques to reduce vibrations WP4

10. Is ELiTES a good example? Not yet a direct common interest item Still Korea may generate a tangible contribution Examples of possible working items Baffles, Optical levers, Some input-output optics,....

11. An example in discussion Baffles to stop stray light Small, critical, self contained project ~ 10 k€ development ~ 100 k€ production

12. An example in discussion Possible multilateral collaboration with Virgo Parallel bilateral agreement can strengthen the working collaboration Link to Italy-Korea exchange program

13. What is the secret of ELiTES The best advice is to identify early simple and concrete deliverable contribution items
