As a new member of ECS, Mitch Cabral has joined the effort and is working on Jama integration, a collaborative web-based tool for reviewing, approving, and exporting system requirements for release. We have begun capturing L2SI Motion and Vacuum System Functional Requirement Specifications (FRS), and although these requirements are still being reviewed and revised, the hope is to make these documents more accessible for projects to follow, and possibly establish these as standards for our control systems. Transferring to Jama will also allow for agile navigation to find conflicts with upstream or downstream alterations in future project requirements between stakeholders and the team.
We released a major ICD detailing the R2A2 between ECS and other groups in HE. It details many important divisions of work and everyone should at least take a quick look through to better understand what ECS does:

NALMS
The NewALarMSystem (NALMS) is almost ready for deployment. After the last updates on the system, the testing section is almost ready to start. Thanks to Thorsten, Omar, Jesse, Ken, Michael, and Victor for all the effort that they are spending on it.
The GMD and XGMD NALMS will be used for testing purposes. To create a dedicated NALMS for GMD and XGMD, several steps were followed:
- Create a spreadsheet that includes all the PV involved in the GMD and XGMD instruments.
- Discuss with the scientists the best value/boolean thresholds that need to be alarmed
- Give a hierarchy to the selected PVs
- Check the PV's value saved on EPICS and update the values and severity according to the spreadsheet
- Create the XML file that will be the core of the NALMS
The picture shows the first attempt of the Grafana board for NALMS GMD-XGMD.
In the future, more PVs will be added to the NALMS. They will be grouped by subsystems (i.g., vacuum, power, common component, etc). For simplicity, to ensure a good understanding and track of possible faults is essential to include in the alarm list only the PVs that are important for the operation purpose. Therefore it is necessary to keep this list as short as possible. Right now, the most critical PVs are being grouped for each subsystem, in the EBD, and in the FEE area, by the DOE summer student Samara Steinfeld. You can follow the upgrade of the NALMS deployment on the NALMS confluence page.
