Below you can find several very useful documents to download. In the beam and detectors document you can learn more about the beam and detectors that you can use for your experiment. The example experiments document is the most important document for the preparation of your proposal. It provides you with short descriptions of different experiments that you could conduct with the beam and detectors available for BL4S. Be inspired by these example experiments – We encourage you to use them in your proposals! The invitation letter provides an exhaustive overview of how to participate in BL4S in one single document. In case something is not clear to you in these documents, don't worry. There are many people – your national contacts and the BL4S team – who are happy to answer your questions.
