Original Requirements for Science Studio : (1)Convenient control of all aspects of an X ray fluorescence (XRF) facility: visible sample, easy sample manipulation, all functions visible, fast response (latency), rapid download (60Mb/min), user- friendly data analysis offline. (2) Similar control of Laue XRD facility (on same beamline), very rapid download (8Mb/s), online data analysis. (3) Control and download from of SEM/ EDX facilities at Nanofab (UWO), running under proprietary software.
Network at present: (1)XRF and XRD facilities at the VESPERS CLS beamline connected to a Science Studio servers at SHARCNET via 1G fibre linkage (XRD still in testing) (2) SEM/ EDX facilities at Nanofab UWO connected to the same servers via standard internet (remote desktop). (3) XRD facilities at beamline at ALS (Berkeley) connected via 10G fibre (to be established this summer)
Original Requirements for ANISE : (Active Network for Interactive Scientific Experiments) (1)Development of real-time interactive software for XRD: (a) Conversion of previous software to serial form configured to run using cell processors(well underway). (b) Adoption of “streaming” software for XRD that is able to incorporate more intelligent features (in progress). (2) Development of similar intelligent real time software programs for XRF spectral recognition and correlation of elemental distribution.
Challenges: (1) Protection of source systems under all circumstances. (2) Obey all user protocols established by the sources. (3) Extend the software to develop new user paradigms (data sharing, discussions, remote teaching sessions). (4) Expandable

Nanofabrication Facility (UWO) The Western Nanofabrication Facility is an open user facility at the University of Western Ontario for the fabrication of micro and nano structures. LEO 1540XB Scanning Electron Microscope (SEM) with an integrated Oxford x-ray system. Oxford x-ray system is controlled by INCA. INCA provides limited control of the SEM, and spectral analysis and quantification.
