The radial collimator
The radial collimator is normally oscillated so that any shadowing of the detectors is uniformly distributed. To move any of the other motors you must first stop oscillating the collimator, restarting it when you're done. There may also be situations where the collimator must be lowered and then raised (in which case you must first ensure that thevcollimator is not oscillating). To perform tasks involving the radial collimator click the dcsgui Settings button and select Collimator.
To start or stop oscillation, or to raise or lower the collimator, click the appropriate button.
To close the collimator window click Dismiss.
