What is FAME+ ?
Considering the technical complexity of synchrotron radiation experiments and the difficulty to obtain beamtime via the various program committees, few new teams having scientific problems adapted to these instruments use the FAME beamline. We decided then in 2004 to organize an annual training for users. This training is organized with the organizational help of the CNRS permanent training and the support of INSU CNRS institute.
The main goals of this formation are to explain:
• the technical aspects of the experiment and the various analysis possibilities,
• the optical adjustments of the beamline.
The training is conceived with lectures, praticals on the beamline and tutorials on computer. To summarize, the training clarifying the FAME operations have several interests:
• open the beamline to the whole communities,
• make more autonomous the actual or future users, from a technical point of view,
• increase the safety on the beamline,
• give to the users a critical glance on all the important points which allow the realization of an experiment under optimal conditions,
• give to the users the up-to-date tools to analyze their data.
This project was initially reserved for the Earth sciences community but it has been quite soon opened to the other scientific communities. Since 2004, 114 trainees issued from 45 laboratories followed this course.

A package including a Windows XP executable, a Linux 64 bits executable, the FORTRAN 90 routines, a set of examples and the manual can be downloaded here, with a folder containing the examples for the tutorial here
Charge Transfer Multiplet Calculations for X-ray Absorption Spectroscopy (CTM4XAS)
The program can be downloaded, after simple registration, here
The software can be installed on windows, following the instructions
Continuous wavelet transformation
The continuous wavelet transformation software has been written by Matthew Marcus (from ALS Berkeley) with LabView and can be downloaded here, on the "utilites" page (on the left).
LabView is not required, but you will need:
• to have the administrator right to operate (not only during the installation procedure)
• to have as a decimal separator a dot '.', not a coma ','
Reference paper of the program can be found here.
Quality Verification of the fluorescence spectra
This is a python source code called canb.py installed on the user's computer. To installed the code on your computer under linux, you should download canb.py
Then you must installed:
•PyQt4 (under ubuntu, install python-qt4)
•Qwt5 (under ubuntu, install python-qwt5-qt4)
Then to execute the program, open a terminal and enter the command: python canb.py
