1. 26 September 2000 Wire Procurement and Wire Joint Production Jack Fowler

2. 26 September 2000 Fowler Duke HEP Sense Wire Procurement  Luma, Osram and Toshiba wires were evaluated  Toshiba was considered the highest quality from initial test  Two pre-series of wire have been procured from Toshiba  Both have been evaluated  One has been approved and is being used in production  Full production order being submitted  Audit of facility tentatively scheduled for Oct 2000

3. 26 September 2000 Fowler Duke HEP Evaluate Cleaning Effects  Evaluate the affects of cleaning the wire in ultrasonic cleaner after wire joint process  First evaluate any damage to the wire due to the cleaning  Second evaluate the effectiveness of the cleaning process  Samples were evaluated uncleaned, after 30 seconds, 1 minute, 5 minutes, and 10 minutes  30 seconds was found to be as effective as longer cleanings
