We propose to set up a small working group of interested people that want to contribute to this new feature. The idea is to define together a set of requirements for this 'actor', then to implement it in Gate, with examples macros and documentation, so that they can be available to everyone in a future Gate release. Here is a very short initial description of the LET actor: - score a spatial distribution of LET (Linear Energy Transfert) - based on the same principle as the DoseActor, or as an option to the current DoseActor - output in kev/mum - several definition of LET exists, so we need to select (at least) one or provide option. I already know the following people/group, that should be interested: - <a href="mailto:ludovic.demarzi@curie.fr">ludovic.demarzi@curie.fr</a> <a href="mailto:fanny.marsolat@curie.fr">fanny.marsolat@curie.fr</a> - <a href="mailto:loic.grevillot@medaustron.at">loic.grevillot@medaustron.at</a> <a href="mailto:alessio.elia@medaustron.at">alessio.elia@medaustron.at</a> <a href="mailto:hermann.fuchs@meduniwien.ac.at">hermann.fuchs@meduniwien.ac.at</a> - <a href="mailto:david.boersma@physics.uu.se">david.boersma@physics.uu.se</a> - <a href="mailto:maigne@clermont.in2p3.fr">maigne@clermont.in2p3.fr</a> and François Smekens Could you please confirm ?
