#'''First find the position of the collimator by performing the collimator wire scan. The current position of the wire for beam center is 4.41 (labeled on the GUI), if the measurement finds beam center at a different position use the expert GUI to set the 3.94 mm SVT collimator to the right position (current position is 6.212, which means that the distance between the wire and the center of the 3.94 mm hole is 1.802). After collimator is in place all beam studies should be done in these conditions with beam currents of 30 nA.''' --> | #'''First find the position of the collimator by performing the collimator wire scan.

* !! Chicane magnets can be energized only when the hall is in Beam Permit, [1]. Chicane magnets must be off if the hall is in Restricted or in Controlled access.
* The vacuum gauge used in SVT interlock (2H03) is broken. Watch the gauge 2H02, in case of a vacuum event valves will close and the beam will be shut-off. If the event is at 2H02 (loss of vacuum near HPS chamber) call SVT expert immediately and follow his/her instruction.
