1 CM20 Meeting April 9, 2013 D.R. Dietderich, LBNL1 Insulation Status for QXF Cables D.R. Dietderich, LBNL LARP-CERN Collaboration meeting April 9, 2013 bnl – fnal – lbnl – slac US LHC Accelerator Research Program

2 CM20 Meeting April 9, 2013 D.R. Dietderich, LBNL2 Outline Status of QXF R&D –Target Thicknesses mm or mm per side HQ/LHQ insulation R&D experience –HQ/LHQ Target thickness mm per side

3 CM20 Meeting April 9, 2013 D.R. Dietderich, LBNL3 NEW QXF Insulation R&D New England Wire (NEW) Target thickness mm per side AGY S2-glass fibers (66 tex) with 933 silane sizing 2 ply fibers twisted with a pitch length of 3”. 48 carriers Braided has 15.4 P/I

4 CM20 Meeting April 9, 2013 D.R. Dietderich, LBNL4 Braid Thickness Reference pressure is 1,000 ksi ~18.2 P/I to obtain mm ~12.4 P/I to obtain mm R&D Results

5 CM20 Meeting April 9, 2013 D.R. Dietderich, LBNL5 New England Wire Braid on QXF Cable Flat-bed scanner image of three cables

6 CM20 Meeting April 9, 2013 D.R. Dietderich, LBNL6 Insulation 14.1 P/I Grey-scale image of the selected area

7 CM20 Meeting April 9, 2013 D.R. Dietderich, LBNL7 Number of pixel: Number of white pixel (threshold 170): (94.67%) Number of black pixel: (5.33%)

8 CM20 Meeting April 9, 2013 D.R. Dietderich, LBNL8

9 CM20 Meeting April 9, 2013 D.R. Dietderich, LBNL9 Summary and Plans Have mm thickness 2 ply braid may produce insulation with target thickness of mm and mm with either 12.4 P/I (picks per inch) or 18.3 P/I, respectively Do not plan to make any new R&D runs for 2 to 3 months Going to focus on QXF cable R&D
