Introduction

With this document a little guidance through the first steps of using VMM3a/SRS should be provided, allowing to successfully operate the system.

For information on which electronics settings to use, have a look here. Or just play with the system and optimise it according to your experimental needs :-)

Tutorial video

In case you are wondering, how to operate the system, there is a tutorial video available.

It is already a bit older and the components have been updated since then. Some of the shown features, like online monitoring via EFU and Daquiri have been put to legacy status and been replace with a more simple to use approach (within vmm-sdat). Nonetheless, the video provides a rough overview on how the system functions. So if you are a new user, it is still recommended to watch the video before going ahead with turning on the system.

Even though some background information is provided in the video, it assumes that you are roughly familiar with the system, i.e. what the SRS is, the components of VMM3a/SRS, etc.

Please read the entire guide and use the search function

There are many reoccurring questions on the system. Most of them have been answered in this guide. Please keep in mind that some of these answers might not be were you expect them. So please check out all categories and use the search function (top bar of this website).

One comment to the reader before the start: please keep in mind that VMM3a/SRS is a powerful system but also a system which is further developed and improved. So not everything may run as smooth as you may think/hope/wish. Therefore, the contribution of the reader to the development of the system and to help to create a mature readout system for particle detectors is essential.

The same applies to this document. It is always work in progress and changes accordingly to the developments on the system.

For changes and suggestions to improve this document, it is recommended to use the standard git tools, so pull requests (GitHub) or merge requests (GitLab). Or just create an issue on the CERN GitLab webpage of this document.

As we are here working with GitLab and in case you might not know how to use git and how to do merge requests, please find some information under the following links (last accessed 27 April 2021):

Contacts

In case of persistent problems, join the discussion in one of the corresponding channels of Discord and post it there. Maybe your question was also already asked there, so please check this before posting.

If you want to contact one of the developers directly, please check out the README files on the GitHub or GitLab pages of the software/firmware projects. Usually the contact details are mentioned there.

If you have a very specific problem, which could not be solved with this document or the above hints you can contact the following people:
