CMSC 2021 Pre-Conference Workshop, June 1, 2021

Irradiation of Materials: how to simulate reactor conditions using ion beams

Ion irradiation is an increasingly popular alternative to neutron irradiation, used to study the effect of radiation on materials’ properties, in the context of nuclear power generation. Its advantages include shorter irradiation times to reach an equivalent dose (roughly 1000 times faster), and lesser activation of the materials (which facilitates handling of the materials for characterization).

In this workshop, the participants will learn about fundamental, theoretical and applied aspects of ion irradiation of materials; proton irradiation in particular. Instructors include faculty in Queen’s University’s nuclear materials group, as well as an invited instructor: Roger E Stoller, retired distinguished scientist at the Oak Ridge National Laboratory.

LOCATION: Virtual remote.

TIME ZONE: All times in EDT (GMT-4), or Kingston, Ontario time.
