A wide variety of measurements can be carried out at 34ID-E: white beam or mono beam, step scans or slew scans, with area detectors or point detectors, depth-resolving or not, etc. Hence a collection of tools are developed to tackle different types of data sets.
A majority of analysis and visualization functions are built into LaueGo, a package developed at 34ID-E based on IGOR Pro which runs on a single PC or Mac.
Data types and formats
- Each exposure of an area detector, if file-saving is turned on, creates a file containing 2D data. By default our detector images are saved in the NeXus format NeXus format, which is based on HDF-5.
- Note: with special configurations, such as the fly-scan mode, multiple exposures can be saved in a single data file as a 3D array.
- Each scan automatically creates a *.mda file that is sequentially numbered. The mda file stores motor positions and pre-selected scaler counts at each scan step.
- Only the motors that are being scanned are recorded in mda files.
- For multichannel analyzer (MCA) fluorescence detectors, total counts of each window of channels are recorded as scalers, and stored in the mda files.
Types of Analysis
Depth-resolved scans (wire scans)
Data from depth-resolved measurements requires reconstruction, which is carried out by a multi-node Linux cluster at APS.
