A model of the Tevatron Collider at Fermilab has been implemented using Monte Carlo simulation techniques. This effort, which began during the Tevatron Collider Run I in 1990, has enabled us to understand the dynamics of operating the Collider.
The plot to the left shows a smaple run of the Model for one week. I
hope to have more charts available Real Soon Now. The scales are mushed here.
A listing of some recent plots of end-store optimizations is availble here.
This is a phenomenological model of Collider operations, with key elements of the operation randomized. In particular, failure and downtimes occur randomly, in agreement with the rates observed in Reality. Also, performances are randomized, also in agreement with the range of possibilities in Reality. For example, the following items represent some of the performance measures that are randomized in this Model:
All fluctuations in performance as depicted in the Modeal are random, that is, performance cannot "improve" in a Model run. The primary use of the Model seems to be, so far, to help to develop intuition on Run Coordinator decisions, like when to end stores and why, and to develop strategies for recovery from failures.
A web interface for you to run the Model for yourself is being developed. You may try it here, but don't expect too much, yet.
