12 Outline Task plan CEA Saclay thermal tests status CEA Saclay thermal modeling status Insulation test sample production at RAL PWR HeII cryostat status Task summary

13 Task plan Achieved Oct 2010 „Sample test map” report Achieved on time

14 CEA Saclay thermal tests status Unirradiated TGPAP - DETD and Cyanate Ester insulation thermal conductivity and Kapitza resistance measurement in HeII condition have been finished. To continue the work the irradiated samples have to be provided by PWR Development of the measurement rig for thermal conductivity and heat capacity in 4-300K temperature range is in the last testing phase where a known aluminum alloy is tested

15 CEA Saclay thermal modeling status Steady-state calculations and Quench simulations with the "conduction" model are finished Development of a simplified He II two-fluid model for the thermal calculation of the magnet. The results will be presented at The CHATS workshop in CERN next week Additional Deliverable (M30): “Superfluid helium transport model for the thermal design of the high field Fresca 2 magnet” is foreseen

16 Insulation test sample production at RAL RAL mix 71, RAL Mix 237 and Cyanate ester thermal and electrical laminates are produced and distributed to PWR and CEA Saclay Mechanical samples will be cut out from 0.5mm laminate to the 6 mm width Tensile Test specimens. Availability of up to 1kN Tensile Test facility at PWR Mech. Dep. is investigated LARP insulation laminates are not produced yet – all components are bought, the production can start on request
