BCM Current in mA
Blue shows the average current over the length of the beam pulse, Pink indicates the maximum value measured during the pulse. The maximum is more sensitive to noise and gives false values if there is no beam. Check date and time for when the last measurement was taken.
Dynamic Display Area
Measurements from up to two devices can be shown here. By default data from current monitors is shown. If a faraday Cup has been inserted or a Wire scanner measurement has been made then those measurements will be shown. If no beam beam pulse has been measured, a "no beam" message is displayed. Note that most instruments display the last beam pulse even if there has been no new beam pulse for a while so check the timestamp
Indicators of basic accelerator status.
Is the beam on or off?
Does MPS allow beam or not?
Is the beam in continuous mode or single shot?
Beam destination and the MPS beam length limit

A list of the available actuators.
If the light is green, the actuator is off its retract limit. For faraday cups, this means that the cup is inserted. For wire scanners, this means a scan is in progress or that it is parked off its retract limit.
Results for these actuators can be seen in the dynamic display area to the left.
A history of beam loss as detected by the Neutron Detectors (ND). Beam direction is top to bottom with DTL00 indicating the first ND along the accelerator. Darker shading indicates more loss, lighter shading indicates less loss.
