  1. DJC Testing at LaTech:Update Qun Yu / Moreshwar Dhole Louisiana Tech University

  2. Quality Control Tests of DJC’s • Continuity and shorts test • Resistance testing • High voltage standoff testing. LaTech Testing Crew: Moreshwar Dhole Qun Yu Matthew Bellot Henry Hollins Qun Yu / Moreshwar Dhole Louisiana Tech University

  3. Since our last report • Updated and improved our database to reflect changes suggested last time and to include results of recent testing • Received 168 50cm-test cables from Century • Commenced affixing backings to cables as per procedure from Jim Fast • In parallel, ~80 of these have been tested Qun Yu / Moreshwar Dhole Louisiana Tech University

  4. On the following slide are sample data from SHEET 1 of the DJC database (http://caps.phys.latech.edu/~greenw/run2b/run2b_page.html) Qun Yu / Moreshwar Dhole Louisiana Tech University

  6. Also on the DJC database spreadsheet is SHEET 2 which has resistance measurements, mean resistances and standard deviations. Part of this sheet is on the next slide.. Qun Yu / Moreshwar Dhole Louisiana Tech University

  8. Some Observations… • We have tested ~125 Century cables. • Of these, ~ 10 cables have some type of defect- shorts between lines, discontinuity, or high resistance. Shorts are the most common of these. Qun Yu / Moreshwar Dhole Louisiana Tech University

  12. 3) High Voltage Standoff Test: • The purpose of this test is to check whether there is any short or current leakage (Arcing) between HV (High Voltage) Cu trace and other adjacent Cu traces. • For this testing here at LaTech we developed our own High Voltage Testing Jig and it is working fine. • This High Voltage Testing Jig allows us to test 10 cables at a time for overnight.

  13. Test procedure: • Continuity: two multimeter probes are connected to both ends of the line in a given cable, if the line is good, there will be “beep” from multimeter. • Short circuit tests: each line is tested against its nearest neighbor. Qun Yu / Moreshwar Dhole Louisiana Tech University
