Welcome
Welcome to the documentation and guide on the VMM3a front-end inside the RD51 Scalable Readout System (SRS).
This guide evolves continuously, as the readout system itself evolves continuously. It will provide you with the information on hardware, firmware and software related to VMM3a/SRS. It can happen that not all information are directly saved on this webpage, but that you will be linked to other webpages or repositories, where you will then find the information you are looking for.
In case you are looking for published references, please finde them as follows:
Articles on VMM3a/SRS (please cite at least one of them, in the case you are using VMM3a/SRS)

Tutorial videos on the VMM3a/SRS operation
Two tutorial videos on the VMM3a/SRS operation exist. One recorded during the RD51 Collaboration Meeting in 2021 and another one recorded during the RD51 Micro-Pattern Gaseous Detectors School in 2023. The video from 2021 contains legacy software versions and is not fully up to date anymore. The video from 2023 is combined with a general introductory lecture on the SRS electronics.

Collaborative effort
As the readout system and all its related components, including this documentation, are a collaborative effort, you are invited to also participate in the collaborative activities. For this please have a look at the VMM3a/SRS related meetings within the RD51 Working Group 5.1 and the community forum:
-
Working Group 5.1 meetings for everybody who is using/wants to use VMM3a/SRS.
-
WG5.1 mailing list (CERN e-group) to access the meetings and receive the invitations. To subscribe by yourself, you need a CERN account. However any email address can be added to the mailing list, by contacting one of the authors.
-
VMM3a/SRS Discord server as community forum to exchange about issues and problems.
