1998 Summer Class

An Incomplete Education in Accelerator Technology

Monday, August 3 through Friday, August 14, 1998
9:00 - 11:00 AM in Curia II, Wilson Hall
Schedule Details & Some Suggested Topics

Aug. 3 - Basic Principles - Steve Holmes
1) Intro/course outline (~30 mins) Bill Foster
Include reading list.
2) Steve will give a talk (derived from his engineering seminar) on basic principles.
- Different types of accelerators.
- Brief into to FNAL accel layouts & params.

Aug. 4 - Linear Beam Optics - Shekhar Mishra
Lecture roughly equivalent to Bryant & Johnsen Ch. 2-4
1) Linear Optics
How magnets bend beams
Weak vs. strong focussing
Matrix formulation
Twiss Parameters
Closed orbits vs. transfer lines
Cell Design
Low Beta
2) Software Machine Design Tools [TBD]
Tour: there will be a Booster walk-thru for the collider grad students at ~10:20 AM. Gary Lauten will give the safety orientation in Curia II at ~10:00, then we will meet with the tour guides in the Main Control room at ~10:20. Tour guides (so far):
Bob Webber
Steve Holmes
Dave McGinnis
Jim Lackey
Gary Lauten
NOTE: a link to a series of very interesting pages on the Fermilab accelerator chain can be found at

Aug. 14 - Controls Systems - Gerry Annala
[Tour: walk all the way around the Tevatron tunnel]

What the control system does on every pulse of the Tevatron.
- fault tree for the accelerator complex
- map of all possible beam transfers
