====== Setting the attenuator threshold interlock ======

With the new OSE this shouldn't be needed anymore, but until then it is necessary to set an attenuator threshold interlock any time primary beam is being sent past the target dump.

The form below goes through the steps to calculate the threshold.  Once calculated, the threshold must be set in the PPS rack.

It is important to note that while the threshold is in place, the attenuators must not be changed without moving out of beam permit.
