Virtual Accelerator for Applications Development and Training
 To enable early testing of applications through the control system, a virtual
accelerator has been implemented to give simulation of the accelerators though
the intended EPICS PV interface. Prototype was set up by the help from DLS.
 Current version is AT/MML version.
 Virtual booster and linac are also possible near future!
 Many facility have such kinds activities: SNS, KEK, J-PARC, DLS, … many
others!

Summary
 The design of the TPS control system is on going.
 All major components for control system are in intensive study.
 Standardization hardware and software are the current focus.
 EPICS toolkit training - a series training activities will be arranged.
 Set up EPICS test-bed
 Single kind of operating system solution for IOCs and consoles are preferred
=> Linux.
 Economic design without scarify performances and reliability are the goals.
 Select possible outsourcing items
 Learn experiences from other labs
