The SXR beamline has several experimental chambers which all process collected data in different ways. Below are instructions for data processing and software used at the SXR beamline:

Step 1: Pre-processing

NEXAFS (can be collected on either the Prevac endstation or the high throughput NEXAFS system): All raw data collected are automatically saved in a binary .mda format. A mda2ascii script is automatically employed to all data collected converting it into ascii format. On top of that a .png image (screen dump) is also supplies of the analysis data program allowing you to see parameters used of each individual raw data file.

XPS (collected on the Prevac endstation): XPS data is acquired using the SPECSlab Prodigy data acquisition software. Raw data is saved in a custom format .sle file, but can be exported in various format including delimited text .xy and VAMAS .vms for use in CasaXPS. Users are able to install, for free, SPECSlab Prodigy on their personal PC for viewing and exporting the data after the beamtime

ARPES (collected on the Toroidal endstation): Data collected using the toroidal analyser are saved as a number of files per scan. The main data is saved as a delimited text files from within the spectrometer control software, as well as a sample image file and some parameter files. These files are viewable in any text editor and contain a sample header within the main data file.

Step 2: Analysis

You may choose to use any data package that you are familiar with / desire to analyse your data. At the beamline we often use the below listed for data analysis:

NEXAFS: QANT GUI written in IGOR Pro. Information of QANT can be found on GitHub

XPS: CasaXPS

ARPES: Data taken using the toroidal analyser can be processed and reduced to a form suitable for detailed analysis using a custom suite of routines written for Wavemetrics Igor (V6 and above). Although not necessary to use, this software provides convenient data reduction of the instrument data and is strongly recommended. If the user wishes to analyze in further detail, the reducted data can be exported in a form suitable for other programs (MatLab, Origin, etc) or analysed within Igor

Important:

The beamline scientists are experienced in SXR data analysis and can provide some general advice in this regard. Please note, however, that it is not a specific task of the beamline scientists to analyse data for users and thus, should you wish to, please pursue their assistance in a reasonable manner.
