SES Software

The hemispherical Scienta analyzers are delivered with SES, a measurement and optimization software which runs on Windows XP. A modern, well-performing computer which meets the requirements of SES is delivered with the spectrometer. The computer also comes with Igor Pro installed for spectrum analysis.

SES supports measurement of several common and rare methods such as EDC, XPS, UPS and ARPES, CIS, CFS and NEXAFS (the latter three requiring monochromator control which is possible to integrate into SES). It can measure these either at a fixed energy or by sweeping the energy, and it displays acquired data continuously during acquisition. The many energy and angular channels provided by the Scienta 2D MCP/CCD detector system is exploited to the fullest in the acquisition software ensuring fast and effective measurements.

SES contains functionality to perform automated series of measurements with individual parameters. The SES sequence manager allows the user to set up for example a multi-point analysis series controlling both spectrometer and manipulator.
 
The SES software is built on a modular concept to encourage development of custom add-ons. The Application Programming Interfaces (APIs) for the analyzer, for the SES add-ons and for the flood gun add-ons are fully documented. Further, VG Scienta will give support to development using these APIs. Developing e.g. an add-on to SES which performs pulsed heating of a sample, in combination with data acquisition is an example of possible customization.

SES saves measurement data in three formats: Igor Binary Wave (.ibw), Igor Packed Experiment Template (.pxt) and a well defined proprietary text format (.txt). The Igor file formats are native to WaveMetrics Igor Pro. These formats are also accepted by analysis packages such as CasaXPS.

Remote control of the Scienta spectrometers can be realized as the functionality in the dll libraries is available for the users directly. To facilitate the external control we provide the SesWrapper – the glue between the SES data acquisition software and external control programs such as LabVIEW, EPICS and TANGO among others. The SesWrapper along with more documentation can be found on the VG Scienta ftp-server:
