13 ID-E Beamline Manual

Useful things to know when preparing for your beamtime:

• Sample Preparation and Mounting options
• Typical scanning times and data rates.
• Links to presentations (slides and some videos) about or featuring the X-ray microprobe.

Running 13-ID-E, including Remote Access

Remote Access:

For remote access, GSECARS is using RealVNC. As your beamtime approaches, we will send links to create a RealVNC account to connect to our data acquisition computers.

Real-time (or close to it) data transfer:

Remote (and local) users will be able to access GSECARS data using the Nextcloud service at https://millenia.cars.aps.anl.gov/cloud.  This works like Dropbox or Google Drive in that data can be sent automatically and “in the background” to your home or lab computer while the data are being collecting.  By using our own Nextcloud service, we can control what data is sent from our data servers to you and without size limits.  Some user documentation for this is at https://millenia.cars.aps.anl.gov/software/CARSCloudData/users.html

Instructional Videos:

A series of instructional videos going through using RealVNC and the beamline control applications for collecting data at 13-ID-E are at this youtube playlist:

Local copies of these videos can be viewed here:

1. Overview of beamline controls and RealVNC
2. Using the visible light microscope and sample stages
3. Collecting and viewing X-ray fluorescence spectra
4. Collecting and viewing X-ray fluorescence maps
5. Collecting XAFS data, writing data collection macros

Data Analysis Tools

We recommend using Larch,  https://cars.uchicago.edu/xraylarch/ for data collected at 13-ID-E.  This includes the GSE MapViewer program for working with X-ray fluorescence maps and the XAS Viewer for working with XANES and XAFS data.
