	Funding: Work supported under auspices of the U.S. Department of Energy under Contract No. DE-AC02-98CH10886 with Brookhaven Science Associates, LLC, and in part by the DOE Contract DE-AC02-76SF00515 A virtual accelerator has been developed at NSLS II to support tools development from physics study and beam commissioning to beam operation. The physics results are provided using Tracy simulation code thru EPICS process variables, which was implemented originally by Diamond Light Source. The latest virtual accelerator supports all major accelerator components including all magnets (Dipole, Quadrupole, Sextuple), RF cavity, insertion device, and other diagnostics devices (BPM for example), and works properly for both linear machine and synchrotron ring. Two error mechanisms are implemented, which are random error for each magnet setting, and systematic error to simulate misalignment. Meanwhile, it also provides sort of online model functions including serving beta function, and close orbit data. In NSLS II, there are 5 virtual accelerators deployed, and 3 of them are running simultaneously. Those virtual accelerators have been effectively supporting the tools development such as physics applications, and other services such as Channel Finder. This paper presents the latest status of virtual accelerator, and our plan for its future development and deployment.

	The Insertion devices (ID) for Taiwan Photon Source are under construction. There are eight insertion devices are under construction. These devices include in-vacuum undulators with or without taper, elliptical polarized undulators. Control framework for all IDs was developed. Hardware and software components are use common as possible. Motion control functionality for gap and phase adjustment supports servo motors, stepper motors, and absolute encoders. The control system for all IDs is based on the EPICS architecture. Trimming power supply for corrector magnets, phase shifter control functionality are also address. Miscellaneous controls include ion pumpers and BA gauges for vacuum system, temperature sensors for ID environmental monitoring and baking, limit switches, emergency button. User interface for ID beamline users are included to help them to do experiment, such as ID gap control and on-the fly experimental. The progress of IDs control system will be summary in the report.
