Action information
Action details
Marco Calviani (2021.07.16): "I would move this to Feb/Mar 2022, as the new gonios are planned to be installed during YETS21-22. We give priority to the installation of the equipment and then we will do the post-mortem. It may take a while depending on whether there is any “major” culprits or we have to take some time to analyze their behavior."
This was closed ex officio by the Chairs on the 1 June 2023: the action was superseded by the recent problem with the new crystal collimator and, to optimize the resources, it was decided to close it.
