  1. TIARA PP TIARA Steering Committee 11th January 2011 - CERN TIARA-PP WP 9 « TIHPAC  » Test Infrastructure for High Power Accelerator Components Sébastien Bousson (CNRS-IN2P3-IPN Orsay)

  2. Important synergies of these equipments with other projects : ESS, ADS (EUROTRANS, MYRRHA)… WP 9 Framework EURISOL is the next generation of a facility aiming at the production of radioactive ion beams (RIB) using the ISOL technique. A Design Study within FP6 has just finished, and 2 key components will require an important R&D program and intense experimental tests to fulfill the Eurisol requirements • The multi-MW target complex • The low beta superconducting (SC) cavities (for driver and post-accelerator) The objective of this WP is to coordinate the definition and the design of two test benches: an irradiation test facility for the high power target developments and a cryogenic test cryostat for testing fully equipped low beta superconducting cavities.

  3. WP 9 : Breakdown of Work

  4. WP 9 : Deliverables and Milestones

  5. WP 9 : Ressources and key persons • The key persons: - CERN : Yacine Kadi - University of Upsaala (ESS) : Mats Lindroos - CNRS (IPNO) : Sébastien Bousson

  6. WP 9 : Start of Work For both sub-task, work is starting by defining exactly what these test infrastructures should be: * Definition and Specification of the Irradiation test Facility * Definition and Specification of the low beta SC Test Cryostat Identification of the User Requirements

  7. All these research items will require experimental studies. WP 9.1 : Irradiation test facilities for MMW target development Full scale test of the MMW target available only in the final facility ! Achieving the design of the full scale target (ex. 4 MW for Eurisol) will require several partial tests: sub-components, irradiation at lower power, instrumentation tests…

  8. Such a cryostat, specific and devoted to low beta SC cavities will be a useful complementary equipment. WP 9.2 : Designing a low beta cavity test cryostat Before assessing that a SC cavity is validated for an operational use in an accelerator, the final experiment is a cryogenic test at nominal RF power of the fully equipped cavity (power couplers, cold tuning systems…) Very few “accelerator configuration” test cryostat are existing in Europe and they are only designed for elliptical cavity testing.
