  • VESPERS — Very Sensitive Elemental and Structural Probe Employing Radiation from a Synchrotron

  • A bending magnet beamline on sector 6 at the Canadian Light Source synchrotron in Saskatoon, Saskatchewan.

  • A hard x-ray microprobe with an energy range of 6 to 30keV.

  • Techniques: X-Ray Fluorescence (XRF) & X-Ray Diffraction (XRD)

  • EPICS — Experimental Physics and Industrial Control System

  • The standard control system at the CLS.

  • EPICS consists of a network of Input-Output Controls (IOCs) which are connected to directly to devices.

  • An IOC provides many Process Variables (PVs) which relate to either an input or output from a device and have a unique name.

  • Channel Access (CA) is used to read or write to any PV without knowing which IOC provides the PV.

  • More than 50,000 PVs in the CLS control system.

  • The BCM provides a high-level interface to the low-level control system (EPICS).

  • Logical and physical separation of business logic and control logic.

  • Virtual device abstraction that provides independence from low-level control system.

  • Virtual devices can be logically organized into a device hierarchy.

  • Basic devices can be combined to build more functional devices.

  • Communication with external applications using two message queues (ActiveMQ).

  • Metadata associated with the operation of a remote controlled beamline and the organization of experimental data collected on that beamline.

  • A project is the top level organizational unit and is associated with a project team.

  • A session defines a period of time allocated to a project team to conduct experiments.

  • An experiment relates a sample and the technique being applied to that sample.

  • A scan records the location of the acquired experimental data.

  • Rich web interface to Science Studio and the VESPERS beamline.

  • Designed to be used over commodity broadband internet.

  • Developed for the Firefox web browser without any additional plugins or extensions.

  • Known to work with other browsers, but requires the Canvas HTML tag.

  • AJAX is used for the VESPERS interface to provide device values in pseudo real time.

  • ExtJS, a JavaScript framework, provides many advanced GUI elements.

Nanofabrication Facility

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.

    User Office Workflow Example

    Prototype Implementation

    1. CLS issues a call for proposals and gives deadline2. Beamline users submit proposals3. User Office administrator ends registration or extends deadline4. User Office administrator assigns proposals to user office reviewers5. Reviewers look at proposals and rank them6. User Office looks at ranking and chooses the proposals to accept7. Accepted proposals contact persons are notified8. Beamline User completes training (web service)9. After training is completed (simulated by a delay) the CLS is notified
