“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 ~420 m 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!”

• The epics-pvdata project – pv. Data • memory resident database – records have structured data – pv. Access • New version of EPICS Channel Access – java. IOC • An engine for record processing and optional support – pv. Service • Service developed against pv. Data/pv. Access

The great integration project…

MATLAB for CLS Accelerator Operations Ward A. Wurtz, Canadian Light Source • CLS relies on MATLAB and the MML for many tasks: – Online accelerator control – Offline data analysis • Extensively use for tasks that do not involve the MML software
