ICTP 2020

Radiation Damage in Nuclear Systems: from Bohr to Young

Applications for this event have now closed

This Workshop will be held at the Abdus Salam International Centre for Theoretical Physics in Trieste, Italy from 11 – 22 May 2020. It assists Ph.D. students and early-career researchers in developing a quantitative understanding of the impact of radiation damage on materials, both for existing fission and proposed fusion reactors. There is an emphasis on the conceptual progression of theoretical and experimental techniques across spatial scales from atomistic descriptions to the macroscopic behaviour of bulk material.

Further practical details are available at the ICTP website page for this event.

Multiscale modelling of radiation damage in materials.

Warning

The ICTP is aware of a scam in which lecturers or participants in Workshops have been contacted by external agencies (by phone or email) claiming to make hotel reservations on behalf of the ICTP and requesting credit card numbers to guarantee the reservation.
The ICTP does not use third parties to make room reservations and always communicates via email. Most importantly, it never requests any credit card details prior to arrival.
Should you experience any fraudulent attempt please inform ICTP promptly.
