The existing Differential Beam Current Monitor (DBCM) has been modified to not only compare beam current waveforms between upstream and downstream locations, but also to compare the previous beam current waveform with the incoming beam current waveform. When there is an unintended change in the beam current, the DBCM now aborts the beam to prevent beam loss on the next pulse. This addition has proved to be crucial to allow beam during specific front-end problems. All data is saved when an abort is issued for post-mortem analy-sis. This paper describes the additions to the implementa-tion, our operational experience, and future plans for the differential beam current monitor.
