1st campaign (2015-2016) : AGATA+VAMOS coupling

The GANIL campaign is organized in different sub-campaigns associated to a main setup

They are organized between the ACC, the GANIL management and the campaign manager

(S.

Lenzi

from the University of Padova)Each GANIL PAC has a “PrePac” workshop with a specific call : AGATA Collaboration Meeting 1st PAC in 2014 : VAMOS (10 experiments approved) 2nd PAC in 2015 : VAMOS || NEDA (10 experiments approved) 3rd PAC in spring 2016 : NEDA (more restricted)
