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

Sébastien Bousson – TIARA-PP – SC Meeting - CERN, 11 th January WP 9 Framework  The multi-MW target complex  The low beta superconducting (SC) cavities (for driver and post-accelerator) 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 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. Important synergies of these equipments with other projects : ESS, ADS (EUROTRANS, MYRRHA)…

Sébastien Bousson – TIARA-PP – SC Meeting - CERN, 11 th January 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

Sébastien Bousson – TIARA-PP – SC Meeting - CERN, 11 th January 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… N°Research ItemsApplication 1Test coaxial guided stream (CGS) Window cooling with laser heatingPerformance 2Test windowless transverse film (WTF) stability with high speed cameraPerformance 3Sub-scale Target irradiationPerformance 4Ultra-sound sensorsInstrumentation 5Pressure sensor capillariesInstrumentation 6Heat Transfer Coefficient (HTC) method improvements with laserInstrumentation 7Primary/Secondary fluid interaction studySafety 8Investigation of the pressure wave from a pulseScience 9Investigation of on-line isotopic separationScience 10Fatigue under Liquid Metal (LM) corrosion and irradiation studyScience 11Influence of wall conditions on LM Heat transferScience 12Long-duration test facilityEngineering 13Dedicated LM Component developmentEngineering All these research items will require experimental studies.

Sébastien Bousson – TIARA-PP – SC Meeting - CERN, 11 th January 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…) WP 9.2 : Designing a low beta cavity test cryostat Very few “accelerator configuration” test cryostat are existing in Europe and they are only designed for elliptical cavity testing. Such a cryostat, specific and devoted to low beta SC cavities will be a useful complementary equipment.
