“MATLAB and MML allow accelerator physicists to perform simple tasks independent of the Controls Department” “For more complex tasks, MATLAB and MML provide a good platform to collaborate with the Controls Department” - Ward A. Wurtz, Physicist, Canadian Light Source

High Level Application Development at the ESS Todd Satogata, Jefferson Lab proton beam through a ~420m superconducting linac

ESS: 12 institutions, 6-7 years write a study… -EPICS to be used at co-located MAX-IV, SNS connections -Linux service layer -Oracle RDBMS Leverage CERN, Jlab SCRF software

“The block diagram not the challenging part delivering a control system, however, is!”
