  1. J-PARC Virtual Accelerator An Accelerator Simulator

  2. USPAS What is the Virtual Accelerator • Virtual Accelerator is an XAL Application • It provides feedback to other applications much like the beam in a real accelerator does • It works in reverse of a normal application • The online model acts as a beam and provides input to diagnostic signals • It uses EPICS control system signals to listen for magnetic field values and also to broadcast diagnostic signal responses • Useful for initial debugging of aplications

  3. What the “VA” Does and Does Not Do Simulates the real beam transverse centroid and beam size motion Provides realistic beam response to BPM signals Does not provide beam size information (but could) Does not provide realistic longitudinal beam behavior to RF settings (assumes ideal RF setup) Reacts to user inputs at the speed that the online model can run usually 1 Hz is easily obtainable – a credibal beam tuning operational rate

  4. EPICS Interface to User / Applications The portable channel access server is used to broadcast the signals for magnets and beam responses Need to build or obtain the PCAS for your cpu architecture This allows development and testing of applications in a realistic configuration – no changes o the application are needed

  5. VA Features Can add random noise to BPM readbacks Provides realistic live beam jitter Can add noise to magnet settings Has the usual XAL sequence selection interface

  6. VA Architecture Continuous loop runs checking magnet field levels, calculating beam positions at BPMs and broadcasting them
