XFEL Users’ Meeting 2015 @ DESY
Jan 27 – Jan 30 all-day

The European XFEL Users’ Meeting 2015 will be held at DESY Hamburg on 28 – 30 January 2015. The meeting will be organized jointly with the DESY Photon Science Users’ Meeting 2015.

The programme of the meeting and other details, including registration, can be found at


We kindly ask you to consider early registration. Please note that the deadline for a poster registration is *15 December 2014*.


We are pleased to announce that we are again able to offer to a limited number of young scientists a financial contribution, depending on distance, towards travel and living expenses. All current PhD students, as well as scientists who obtained their doctoral degree after 1 January 2013 are eligible. We encourage you to forward this information to science graduate students or recent PhD’s who might be interested. Deadline for application is *Thursday, 11 December 2014*.


When booking your hotel accommodation, you should mention that you are a visitor to European XFEL / DESY. Otherwise you might be asked to pay a tourism tax on your hotel bill. A list of hotels can be found on the meeting website.

Spectroscopy Lectures :: theory and codes @ CECAM-HQ-EPFL
Jun 18 – Jun 19 all-day

The CECAM School on: “Theoretical Spectroscopy Lectures: theory and codes” reaches the 6th edition and takes place from 18th to 22th of May, 2015 at the CECAM-HQ-EPFL, Lausanne, Switzerland.

Electronic excitations are probed by experimental techniques such as optical absorption, EELS and photo-emission (direct or inverse). From the theory point of view, excitations and excited state properties are out of the reach of density-functional theory (DFT), which is a ground-state theory. In the last twenty years other ab-initio theories and frameworks, which are able to describe electronic excitations and spectroscopy, have become more and more used: time-dependent density-functional theory (TDDFT) and many-body perturbation theory (MBPT) or Green’s function theory (GW approximation and Bethe-Salpeter equation BSE). In fact, computational solutions and codes have been developed in order to implement these theories and to provide tools to calculate excited state  properties.The present school focuses on these points, covering theoretical, practical, and also numerical aspects of TDDFT and MBPT, and codes implementing them (ABINIT, DP, EXC).

The presentation of the theory will be followed by practical classes and hands-on  tutorials. At the end of the school, students will have sufficient working knowledge to  pursue their projects at their home institution. The participants are expected to have a fair knowledge of DFT prior to the school (see Ref. 1, given in the school’s website) and to be familiar with one plane-wave pseudopotential based software.
Indeed, although at the beginning of the school, we will make sure that the DFT level of all participants is enough in this respect and provide the needed complementary  information and training, the purpose of the school is to go beyond DFT, with hands-on exercices based on plane-wave implementations.

The deadline for application is on 15 April 2015, but giving the limited number of places (around 25) many applications will be considered even before the deadline. Especially student candidates coming from outside EU are encouraged to register soon: an answer to them will be given as soon as possible for VISA and traveling purposes.

In order to apply for the school, please go to:

Aug 22 – Aug 28 all-day

The upcoming 16th International  XAFS16 International Conference on X-ray Absorption Fine Structure ( will be held in Karlsruhe/Germany, August 23-28, 2015.

A 1-day symposium (organized within the main conference) entitled “Current and future opportunities for X-ray spectroscopies at XFELs”, will  provide a broad overview of the current status and challenges for various types of X-ray spectroscopies at the recently operational X-ray Free Electron Laser Facilities (XFELs), including XAFS, non-resonant and resonant XES. The emphasis will be given to ultrafast time-resolved X-ray spectroscopic studies exploiting the unique and unprecedented brightness and ultrashort pulse duration of these 4th generation light sources exploiting both soft and hard X-radiation. It will also highlight the future opportunities for X-ray spectroscopies in the context of the rapidly improving XFEL technology. 

We are now in the process of finalizing details of the symposium program and we would like to strongly encourage you to submit abstracts to XAFS16 concerning Session 17: “Spectroscopies at XFEL sources, Time-resolved and ultrafast techniques” (see the following link for a list of all topics for abstract submission:

Both invited/contributed talks will be selected from the abstracts, next to poster presentations. The extended deadline for abstract submission for XAFS16 is in a few days only, March 15th, 2015.
