Detector Cooling Services

Cooling services for the pixel detector deliver liquid C3F8, which then evaporates and returns to the cooling plant.  The tubes and connections (fittings) are small in size, must be rad hard, and very leak tight.  Here is some specific information about fitting designs and testing protocols/results:

Drawings and Fitting Information
• Drawings of Variseal Fitting and Test Piece
• Laser Welding Drawings (sample and sector)
• Variseal Data Sheet (proposed size as of Dec. 2000)
• Laser weld pictures (samples by EB Industries, Inc.)
• Fred Goozen's Luer Lock Type Designs (see top of page) - 11 December 01
• Tally of Luer and Indium Fittings to be Machined - 11 December 01
• U-TUBE Information Page
• Fitting Sketches (of the models) of the Luer Joints, Indium Joints
• Test Weld Extension Piece - Test Glue Extension Piece - NEW!!
• Dummy Weld Fittings for Testing - NEW!!

Cooling System Information
• Requirements Document (from EDMS)
• Cooling System Tubing Sizes
• Sector Cooling Circuit.zip - Pro/E Model, .stp file, and .igs file (Includes all fittings and tube sizes up to, but not including, PP1)

Fitting Testing Information
• Original Complete Testing Regimen (Up to July 2001)
• New Testing Regimen and Initial System Pressure Calcs. (agreed with Stave engineers July 2001)
• System Pressure Calcs. Chart (no text - please read assumptions above)
• He Leak Checker Schematic
• New Test Results Recording Sheet (August 2001)
• Helium Leak Equivalents (for Refrigerants) - Courtesy of Vacuum Instruments Corporation

Fitting Test Results
• Variseal/Indium/Luer Lock Test Results (August 2001)
• Luer Lock Results from New Regimen (Luer Lock samples only) (September 18 2001)
• Fitting Comparisons (size, area, material - Luer, Indium, and Variseal) November 13 2001
• Alloy Composition Test Results (November 2001, Conducted by Fti Anamet, Inc., Hayward, CA)
