Experimental Data and Policies

User Club

The ILL User Club provides online access to all the information and administrative tools for our scientific visitors, presented in a user friendly environment.


This service is intended for ILL users that would like to download large volume of experimental data. 

In order to use this service you need a sftp client software on your local computer, we recommend the open-ssh solution (the standard Command Line Interface for unix based systems) or FileZilla (Windows, Linux, Mac Os X) for those who prefer a graphical environement. Nevertheless any sftp software should work out of the box but pay special attention to the fact that it provides the functionallity to resume failed transfers.

This service is hosted by (standard SSH port, i.e TCP 22), you need to authenticate using your ILL account. Once connected, you will find the usual "MyData" folder containing the proposal data folders organised by Year or Instrument.
