Floor Coordinators may be called upon
to alter the Global Online status of a beamline. Upon completion
of this module, the FC should understand the importance of Global Online
and feel comfortable executing the steps to take a beamline offline and
subsequently restore Global Online status.
Global Online is a system by which
the FC grants permission for a particular beamline to run.
When the FC turns the key to place
a beamline Globally Online, a valve is opened and air is provided
to open the two safety shutters located inside the Front End of that beamline.
In order for a beamline to be placed Globally
Online, both the machine protection system (ACIS) and the personnel safety
system (PSS) must agree that it is safe for beam to enter the front end.
