abstract = {{ISIS operates a high intensity 50 Hz rapid cycling synchrotron (RCS), accelerating up to 3 x 10¹³ protons from 70 to 800 MeV. Protons are delivered to one muon and two neutron targets over two target stations, totalling 0.2 MW of beam power, enabling around 1000 experiments for approximately 3500 users a year. Minimisation of beam loss and optimisation of its control are central to achieving the best facility performance with minimal machine activation. We summarise recent work aimed at improving loss control in the RCS. Using geodetic survey data we aim to develop lattice models with realistic magnet alignment errors in cpymad. Building on recent measurement campaigns a new and improved system of tune control has been developed and verified using enhanced lattice models with cpymad. More rigorous and quantitative measures of beam loss have been implemented in graphical user interfaces (GUIs) using the QT GUI toolkit python interface PyQT5, and streaming data using the messaging protocol MQTT, in order to optimise loss control.}},
