The next joint celebration QENS/WINS will constitute the 14th Edition of the QENS series and the 9th of the WINS workshops. Due to COVID, we will celebrate an online version of QENS/WINS during 17-21 May 2021 (QENS/WINS2021). A face-to-face Conference (QENS/WINS2022) will take place in San Sebastian, 23-27 May 2022.

QENS/WINS 2021 will span over the five days 17-21 May 2021. From 14:00h to 16:30h Central European Summer Time, Keynote and Invited talks will be offered, as well as a 30-minutes ‘coffee break’, that will allow communication among all the participants. The talks will be recorded and will be available the day after to all the interested attendants. In a ‘moodle’, all information about the Conference will be available. Forums will be open where participants can pose / answer questions and exchange ideas throughout the meeting. In addition to the invited talks, poster-like presentations (including the possibility of videos and other complementary information) will be accessible for all attendants along the 5 days.




Following the spirit of QENS Conferences since 1992, the main purpose of QENS is to cover the broad spectrum of scientific activities related with the investigation of material dynamics using quasi-elastic neutron scattering techniques (accessing both, frequency and time domains). QENS will offer a platform for discussion and exchange of scientific ideas among the experts in this field, and a general overview to newcomers about the capabilities of QENS in exploring atomic and molecular motions and relaxation processes of novel materials. As a novelty, this QENS Edition will explore and exploit the potential synergies between different methods (including experimental techniques and simulations, but always with QENS in the spotlight), in order to face diverse scientific challenges emerging in different research fields.

 The following scientific topics will be covered:

  • Dynamics of liquids in different environments and under confinement
  • Dynamics of polymers in bulk, blends, gels, membranes, films, composites etc. at different length scales
  • Function/dynamics relation in biological and bio-related systems
  • Role of dynamics in systems of medical relevance
  • Transport mechanisms in energy-related materials
  • Dynamical processes in soft matter, including liquid crystals, self-assembled materials, colloids, etc.
  • Dynamics of novel materials for industrial applications
  • Relaxation phenomena involved in the glass transition
  • Lattice dynamics and Spin dynamics of magnetic systems

Complementarity with the following methods will be explored:

Experimental techniques:

  • Spectroscopic and relaxation techniques like e. g., dielectric spectroscopy, NMR, rheology, calorimetry, etc
  • Other scattering techniques providing dynamic and/or complementary structural information, like e. g., dynamic light scattering, Brillouin scattering, X-ray photon correlation spectroscopy, diffraction, small angle scattering…

Simulations and Theory:

  • Molecular Dynamics Simulations, including fully atomistic and coarse-grained models
  • Monte-Carlo simulations
  • DFT, Analytical methods, …




WINS --the 9th Workshop on Inelastic Neutron Spectrometers– will cover innovative aspects of neutron instrument design. Progresses on new spectrometer projects will be presented. As in previous editions, the theme of “New idea, New concept, New design, New instrumentation for New sciences” will be followed. New developments in the application of polarization analysis, magnetic field, pressure, or improvements in sample environments for soft matter systems will be covered. Software for data acquisition, analysis and instrument simulation will be also part of the program. In analogy with the spirit of the QENS counterpart, the synergy with complementary methods –in this case mainly with advanced simulations and extensive Monte Carlo simulations—will be emphasized.

The workshop will consider:

  • New ideas, new concepts and new designs for neutron spectrometers
  • Novel devices, detectors and sample environments: polarization, magnetic field, pressure, soft matter environments
  • Software for data acquisition and analysis
  • Complementary computer methods for instrument simulation


Why a joint QENS/WINS?


QENS focusses on the discussion and exchange of scientific ideas related to the investigation of atomic and molecular motions, while WINS deals with instrumental aspects of quasielastic and inelastic neutron scattering techniques. Though originally QENS and WINS were held in an independent way, the added value of their joint celebration has been put forward since it enhances their scope and impact on the scientific community related with the quasielastic and inelastic neutron scattering techniques.

Young scientists involved in neutron scattering investigations can particularly profit from this joint event (and are especially welcome).


Diversity Statement


QENS/WINS invites participation from people of all races, ethnicities, genders, sexual orientations, ages, abilities and religions.
