Example#1. Cu-Cu2O

Example 1. Cu/Cu₂O Cycling Experiment

Experiment was performed at NSLS on X17a beamline. In this experiment the capillary with Cu-powder was heated to 500K and the 5%O₂ in He was flowing through the sample for 30min, then oxygen stream was changed to the 5%CO in He and this mixture was flowing for another 30min. Such cycle was repeated 5 times. Between each cycle two empty data sets were collected to separate cycles one from another.

1. Opening the Program.

You can start 2DFLT and load files from the experiment by two different ways: Using desktop shortcut or directly from Windows Explorer. Both ways are presented here and you can choose any of them.

Using Desktop Shortcut. Double click on 2DFLT shortcut on your desktop and the file selection window will open. Navigate to the Examples folder and in this folder select and open folder Cu_Cu2O. Select first CHI-file in the series (O30C30_min-00000.chi) and press open.

The program should read first file and automatically find number of all files with same experimental code (O30C30_min). See below

Using Windows Explorer. You can also open the data directly from Windows Explorer To do that in Windows Explorer navigate to the …Examples\Cu_Cu2O folder and select first file in the series (O30C30_min-00000.chi) right click with a mouse on and in menu select Open with.

In the opened window unclick Always use selected program to open this kind of file (unless you want that all CHI-files will be automatically opened with 2DFLT) and press on the Browse… button. In opened window navigate to the 2dflt folder and select 2dflt.exe and press Open.

On the last window press OK and the 2DFLT program should load first file and automatically find all files with similar name in this folder. The advantage of this method is that if next time you want to use 2DFLT to pen other CHI-files on your computer you can right click on the first file in the series and under Open With the option 2DFLT will be available.

2. Loading the Data.

At the end all methods should produce similar window:

As you can see program automatically loads first file and finds number of files with similar name in the folder. In our case it is 610-files, first one is automatically loaded, hence program will ask how many after first one you want to load. As default it is all files (609) Hence if you want to load all files just press Enter. As a general rule all default options are presented in square brackets([…]) if you want to use default option just press Enter.
Program then will ask you the File increment to read (e.g. every file is 1, every second file is 2). Press Enter since we need to use all files in the folder. After the loading of the files is done program going to ask to provide the units for the X-axis. In this case we are using 2 Theta angles in degrees (option T).

After pressing Enter all data have been loaded and program goes to the Main Menu.
