Dear all,
experiments and technical stuff occupy a large fraction of our time, to conceive or choose material, to specify it, to design experiments, to make sure that you will have the right components, that they will match what you want to do, that you can fit your budget to your physics (or vice versa…). In order to save some time for everybody, the Working Group 1 (Tools and Infrastructures) of the COST Action has created a discussion list, where you can ask your technical questions, and where you can also reply to others so that information can be better and more rapidly shared. Those of you interested to become a member of the discussion list, please write an email to danielrodriguez@ugr.es”
Best regards,
Your editorial team
