Our gloal is to only develop open source tools. You will find here a list of the major -repositories hosting our programs
- -This site is designed to help you with the preparation of your -experiment and subsequent data processing and analysis. If you are not familiar with neutron imaging and may be -interested in collaborating with us, visit the publications page to review the science we do.
- -For industrial applications, please contact Hassina Bilheux
- -We recommend that you discuss your experiment with the instrument team as soon as you receive -approval of your beam time.
-We would like to thank the contribution from the research community in the implementation of this -web site, and always welcome your comments to improve it (contact -Jean Bilheux).
-Web site logo: Ryzewski K., Herringer S., Bilheux H.Z., Walker L., Sheldon B., Voisin S., Bilheux J., Finocchiaro V., Neutron imaging of archaeological bronzes at the Oak Ridge National Laboratory Physics Procedia, 43, 343-351 (2013).
- -This must be completed by all participants to the experiment before the first day of experiment.
-Received training e-mail from user office (neutronusers@ornl.gov)?
- -Completed online training if assigned? ORNL guess portal
- -Scheduled onsite training and tour for HFIR access?
- -Followed attached procedure to access CG-1D data?
- -Followed attached procedure to access CG-1D analysis computer?
- - - - - -In order to optimize your experiment time, we recommend you to go through the -check lists from this Before your Arrival menu.
- -Feel free to print out the pdf version -and check out the items one by one.
- -
To be completed by the Principal Investigator (PI) of the experiment at least 3 weeks before beam time.
-You can access your proposal using the IPTS page
- -Confirmed samples (adding any new samples, and including composition)?
- -Confirmed need for lab space?

If you prefer to bring your samples, please go first to the Sample Management Desk located in the Cold Guide Hall -and work with Kristin Nevius to have all your samples labeled with an item Barcode before -proceeding to the beamline.
- - - - - -For any personal tutorial, demonstration or request, please contact Jean Bilheux.
- -In order to analyze or visualize your data, please follow the following recipe.
- -Using your favorite browser, go to https://analysis.sns.gov
- -
-
Enter your XCAMS and your password and hit Login
- -The first time you log in, you will be presented the following display
- -
just click OK to finish up logging in.
- -And if it is not the first time, you will probably see a black screen. Just click anywhere within the window -to activate the screensaver log in.
- -
Enter your password and click Unlock.
- -
You are now connected to our analysis computer.
- - - - - -This will require that you complete 2 steps:
- - - -1. Create an XCAMS account
- -If you have not done so, please create an XCAMS account
-
2. Request access to HFIR data
- -You can request access to your data by visiting this page https://neutronsr.us/accounts/request.html

- -If the goal is to bring your data to your computer for local visualization and analysis -not recommended due to the size of the data -and the tools we offer via our analysis computer - you can either use:
- - - - - -1. Install FileZilla.
- -2 Create and configure a new bookmark
- -
Enter the information as followed:
- -Click Connect
- -
You can now browse to your data by following the structure /HFIR/CG1D/IPTS-XXXX
- -
3. Import Data
- -If you want to copy your data to your local computer, simply DRAG and DROP the folder of interest into your -Desktop display on the left side of the window.
- -
1. Install Cyberduck.
- -2. Create and configure a new bookmark
- -
Enter the information as followed:
- -Click Connect
- -
You can now browse to your data by following the structure /HFIR/CG1D/IPTS-XXXX
- -
3. Import Data
- -If you want to copy your data to your local computer, simply DRAG and DROP the folder of interest into your -Desktop.

If you get lost in the file system, here is a typical map of the file structure.

This tutorial explains how to use SNS jupyter notebook site to perform CT reconstruction.
- -You will find this tutorial here
- -
The notebooks must be run from top to bottom. Place the cursor in the first cell and either click the -
icon, or by using the keyboard shortcut SHIFT + ENTER. - -This is showing a busy notebook with the background cell green and the full circle at the top right corner of the notebook.
- -
At least one time per notebook, you will need to select a folder or one or more files. This widget will look like this
-
The UI is pretty self explanatory but you just need to know that:
- -In the file/folder listing widget
- -The file or folder will be really selected only once you have clicked the Select -button at the bottom right corner.
To select more than one file (when this option is available), CLICK first file then SHIFT + CLICK -the last one. Or ALT + CLICK to individually select each file.
The cell is then executed and depending on the contain of this one, you may see or not an output to the cell. -The output is always displayed just below the cell ran. In some of our notebooks you will see widgets that you will -need to interact with. Here are a few examples of widgets you may encounter in your notebook.
- -
-
In some notebooks, the output may even show up in the back of the notebook (the default cell output will give you a -message that let you know where to look). Those outside widgets are more complex user interface such as the one shown -here.
