  A new pattern memory system has been built from PXI bus modules to ramp the booster synchrotron magnet and RF power supplies, replacing an old and proprietary Toshiba system. The new system is compact, rugged, easy to program using LabVIEW, easy to repair and low cost.

  The Siam Photon Source (SPS) is a dedicated synchrotron radiation facility located in Nakhon Ratchasima, Thailand. After successful commissioning and recent energy upgrade from 1.0 GeV to 1.2 GeV, the Siam Photon Source is currently well into user mode of operation. The light source is now providing routinely synchrotron radiation in the vacuum ultraviolet and soft x-ray spectral ranges to both internal and external researchers. In this report we describe the overview of the current machine performance including user availability, the progresses made recently, and the planned machine improvements, which emphasizes on improving beam stability and machine reliability. Plan to install two insertion devices, a permanent magnet planar undulator and a superconducting magnet wavelength shifter, is also discussed.
