Subsubsection - When to Optimize

Beam optimization may be done any time a run is not in progress. It was very popular after a beam fill when the ALS was running in Decay Mode; however, Top-Off Mode keeps the optics at a constant temperature. That said, it doesn’t hurt to optimize often. One popular practice is to start a beam optimization before collecting a dataset, filling in collection values while the beam is optimizing. Collection may proceed once optimization is complete.
