Abstract :
The repetition frequency of a linear collider can deviate substantially from nominal design values as a result of lost pulses. Pulses are typically lost as a result of a veto imposed by the many machine protection systems (MPSs). A system has been installed at the Stanford Linear Collider (SLC) to use the existing beam position monitor hardware to count every beam pulse that passes each of the strategic locations. Also counted are the signals from various beam dumpers, as well as trigger signals generated by the MPS. Representative data of SLC running that have been used to determine how to improve running efficiency are shown.<>
