The Controls Group for TRIUMF's 500 MeV cyclotron developed, runs and maintains a software application known as The Scans whose purpose is to: a) log events, b) enunciate alarms and warnings, c) perform simple actions on the hardware, and d) provide software interlocks for machine protection. Since its inception more than 35 years ago, The Scans has increasingly become an essential part for the proper operation of the Cyclotron. This paper gives an overview of The Scans, its advantages and limitations, and desired improvements.

In the pursuit of progressively more stable beam currents at TRIUMF's 500 MeV cyclotron there was a proposal to regulate the beam current split ratio for two primary beamlines with closed-loop feedback. Initial runs have shown promising results and have justified further efforts in that direction. This paper describes the software to provide the closed-loop feedback, and future developments.
