Materials Research Program Advisory Committee (Mat-PAC)

GSI has established a Materials Research Program Advisory Committee (Mat-PAC) that evaluates experiment proposals submitted to GSI in the area of materials research. The Mat-PAC members give advice to the GSI directorate on selecting experiment proposals that are submitted by individual users or user groups. Following periodic calls for proposals, the Mat-PAC meets to evaluate experiment proposals on the basis of scientific merit and technical feasibility, and makes recommendations on the amount of beam time to be allotted.

Date of the next Mat-PAC Meeting: 16 - 17 June 2020

Though this year's G-PAC meeting has been shifted from June to August due to the Covid-19 pandemic, the Mat-PAC meeting will take place as videomeeting in June as planned.
