Workshop to involve more US postdocs and students and their home institutes in all aspects of tracking: Remaining performance validation for run 1, performance for run 2, studies for phase 2, and hardware for phase 2. Format: Several parallel activities with few introductory and summary talks. Each activity is run by an instructor. Each participant signs up for one activity. There will additionally be a lecture series on track reconstruction presented by Markus Elsing, and a mini course on B-tagger tuning presented by Tobias Golling. See Scientific Program and Timetable for details. This is a working meeting. There is no registration fee. Participants should expect to learn new skills and get some work done- not to listen to talks.
