  1. Collaboration of TE-VSC-SCC with straw-material working group NA62 • Coating adherence tests • Permeation results • Surface analysis results Wil Vollenberg and Delphine Letant-Delrieux TE-VSC-SCC NA62 straw working group meeting; 18-10-2010 W.V. & D.L.D.

  2. SAMPLES FROM: Pilot coating run by FEP: • - Melinex 406; Cu50/AU20: CO2010-07-07A-01 • - Melinex 406; Cu100/AU20: CO2010-07-07A-02 • Hostaphan RNK 2600; Cu50/AU20: CO2010-07-08A-01 • Hostaphan RNK 2600; Cu100/AU20: CO2010-07-08A-02 Coating adherence test at FEP by cross cut test: Cross cut: 11*11 cuts Calibrated scotch on it Pull Percentage of squares that peels off. NA62 straw working group meeting; W.V. & D.L.D.

  3. Adherence tests at CERN:cross test and scotch test Hostaphan RNK 2600 50 Cu + 20 Au 100 Cu + 20 Au NA62 straw working group meeting; W.V. & D.L.D.

  4. Adherence tests at CERN:cross test and scotch test MELINEX 406 100 Cu + 20 Au 50 Cu + 20 Au NA62 straw working group meeting; W.V. & D.L.D.

  5. Items not yet understood: Adherence problems at PEF for Melinex 50 + 20, at CERN Melinex 100 + 20. AT CERN: Aging of samples: Melinex 100 + 20: better adherence after aging ?? Tests of aging in controlled conditions: 100 Cu + 20 Au 50 Cu + 20 Au NA62 straw working group meeting; W.V. & D.L.D.

  6. Adherence tests at CERN:scotch test Hostaphan RNK 2600 50 Cu + 20 Au Melinex 406 50 Cu + 20 Au NA62 straw working group meeting; W.V. & D.L.D.

  7. Items not yet understood: Good adherence for Coatings on Hostaphan RNK 2600, independent of thickness / aging conditions Some unexpected results for adherence of coatings on Melinex 406. NA62 straw working group meeting; W.V. & D.L.D.

  8. Permeation results NA62 straw working group meeting; W.V. & D.L.D.

  9. Uncoated samples coming from rolls coated by Fraunhofer (CA1509465) Surface analysis results (XPS) NA62 straw working group meeting; W.V. & D.L.D.

  10. Future activities • Permeation (Ar and CO2) determination of: • Hostaphan RNK 2600 Cu100/Au20 (ongoing) • Hostaphan RNK 2600 with welding NA62 straw working group meeting; W.V. & D.L.D.
