"Because of the international alert on the COVID-19 infection, the ET steering committee discussed the impact of this unexpected situation on the ET symposium organisation. The committee evaluated that the efficiency, the attendance and the success of the symposium could be seriously compromised by the difficulties and obstacles in travelling we are experiencing.
For this reason the steering committee decided to postpone the 11th ET symposium to a new date to be defined when the international situation related to the COVID-19 infection will stabilise. The conference fee will be reimbursed.
We are investigating the possibility to have a 1-day meeting through videoconference."

The 11th ET Symposium is hosted by the LAPP-CNRS laboratories in Annecy, France. The meeting begins the 30th of March, 9am, and ends the day after, 31st of March, at 14:00. The 31st of March afternoon session will be devoted to specific discussions on design issues. Registration and additional information are available in the web page:
