Status of cooling components
• Received from Medelec:• Phynox tubes• CuNi capillaries
• Processing started: • Squeezing• Ni+Cu layer on tubes ends• Fittings procurement

Recent actions
• Realization with M. Pimenta dos Santos (TS-CV-DC CERN) accomplished
• First test performed in October
• Foreseen installation (temporary) in bld. 23 for qualification

First test of cooling plant
Two-days hands-on course c/o TS-CV-DC• Manual setting of parameters (no automatization)• Use of a two-sectors-like setup • A few sets of parameters have been exploited
• different power dissipations• variation of liquid/vapor pressure
A first contact: some impressions, extensive test in order…

Test setup
• Final compontens of freon circuitry• Dummy staves: resistors mounted on kapton• Mount on carbon fiber• Thermal contact is the main issue

Integration
• A mock-up of half detector has been installed in Padova
• It is being upgraded as needed• First tests:
• near-detector cables integration• beam pipe support positioning
both on RB26 side
November 16, 2004 14
Cables layout
• MCM- and bus-extenders have to go around input (output) capillars being twisted ~90o
• Protection of capillars under study

Summary and plans• Cooling plant up and working
• First test has been encouraging:• ease of startup• seamless power absorption (in test setup)• wide range of parameters tuning• emergency procedures implemented
• Mock-up of SPD implemented• Effective for debugging of integration issues • RB26 side started
• NEXT• Planning of extensive test of cooling plant for tuning on
real conditions• Mock-up upgrade up to first patch panels and RB24 side
