ATLAS Pixel Detector Project
Internship Details
• Begin Date – May 1, 2002– ATLAS Pixel Detector Project 50-75% time (E. Anderssen)– CXRO adjustment stage design 25-50% time (S. Rekawa)
• As of December 2002– ATLAS Pixel Detector ~100% time– Minor follow-up with CXRO
• Development and Training– Pro/E introductory training (1 week)– Laser Safety training/Laser eye exam– Standard ergonomics/GERT/lab safety training
• Professional Exposure– Travel to CERN – presentations given at Review Meetings
• December 2002 – Mechanics Meeting• February 2003 – Production Readiness Review• Planned April 2003 – Final Design Review
– “Internal” Reviews at LBL• June 2002• September 2002

Rail Overview
DETAIL Flat RailDETAIL V Rail
Vee and Flat rails were chosen to provide pseudo-kinematic support for the detector during delivery to the support points.
Rails are used only for delivery, not support.

Future Plans
• Internship Ends May 1, 2003– Alexis will continue 100% time with ATLAS– End of Pixel mechanics production ~spring 2005– Supported 100% by project until at least ~summer 2004
• Current Responsibilities – next 6 months– Design of insertion scheme for Pixel “Package”– Integration of rollers/sliders into package design– Design of insertion “driver” mechanism– Testing of limited insertion “dry-fit”
• Future Plans– Assignments to be determined
• Larger integration role• Testing/validation of composite components (maybe more
analysis)
– Continued presence at CERN meetings
