MEC-U
MEC-U Controls has slowly begun ramping up in March and April, and we look forward to continue the trend as we shift focus to laser beam transport controls and infrastructure design. Some notable MEC-U topics from the past couple months can be found below.
Rack Estimates: WIP
Estimated control rack and power quantities for base scope and full scope. Looking forward to meeting with various rack vendors. Visits with Rittal and Steven Engineering in May.
NNSA and DMPL: WIP
Explain what NNSA is and what DMPL is. How is this different from base MECU scope. Controls giving cost estimate for additional scope.
FAC Review: WIP
The Facility Advisory Committee Review is not a critical path review, but is an opportunity for each subsystem to present their progress, designs, challenges to experienced personnel who have background in similar laser facilities and projects.
Talk about charge question.

Overall Architecture
Jira: WIP
We are currently organizing ECS and SLAC CosyLab work through Jira and an MEC-U Kanban board. So far, the board has proven to be effective at increasing visibility of the tasks to be completed at the SLAC Controls Level. Each tasks is organized under an epic, and (most) epics correspond to project activities within P6.
pcds_conda
pcds_conda version pcds-5.7.1 has been released! We released pcds-5.7.0, found a few issues, and then released pcds-5.7.1 a week later.
The intention of this release is to fulfill some long-standing package requests and to get us ready for the new run with a stable python foundation.
Full release notes here:
We're preparing for a migration to python 3.10 and pyqt 5.15 within the next few months. This is for both performance and security reasons, as fewer and fewer new package versions support old builds of pyqt and of python. In particular, we're going to quickly run into a problem with openssl incompatibilities as openssl 1.1.1 reaches end of life and no longer receives security updates.

Stepper Motor Torque Calculations and Serial Impedance Matching
Two new whitepapers were prepared to help resolve some commonly asked questions and points of confusion.
- Stepper Motor Sizing: This page is intended to help determine the pullout torque required for a particular application, given some mechanical parameters. The page also covers the effect that microstepping has on the motor torque, and why it should not be used for increasing resolution.
- Cable Impedance Mismatches: This page is intended to help evaluate the effects of an impedance mismatch between a signal's source, cable, and destination. Some mismatches are tolerable, while others are not. This page provides resources and a built in calculator to help with these evaluations.
Record of decision regarding Micronix systems
After much discussion and evaluation, a Record of Decision has been written regarding the use of Micronix piezo systems in future designs. This is discussed in more detail here, but is outlined below:
- The Micronix MMC-100 has a history of communication issues, requiring specialized controller knowledge, leading to a burden on operations.
- The MMC-100 control has therefore been deemed EOL (end of life) in the Supported Devices List, and is considered to be legacy equipment. This means:
- The MMC-100 may only be purchased to replace non-functional units that have already been put into operations.
- Any units that are already in operations are strongly suggested to be replaced with LTS (long term support) equipment.
- The MMC-100, even if the hardware is already in use in LCLS-I, may not be re-used in upcoming projects such as LCLS-II HE.
Please direct any questions regarding this Record of Decision or the Supported Device List to ECS.
NALMS
The NALMS project has made significant strides in recent months, but the team faced some technical difficulties during the final phase of development. While the NALMS deployment in S3DF Kubernetes is almost complete, there are still some communication issues that need to be resolved. To track these issues, the team has created an epic ticket on Jira that outlines the remaining tasks that need to be completed in the coming weeks to achieve a full deployment.
Despite these challenges, the project has reached a prototype stage where it is ready for use, and the team is eager to receive feedback from users.
A recent demonstration with major users Bill and Stefan, for Vacuum and GMD and XGMD fields was successfully completed.
If you're interested in trying out NALMS, there is a dedicated web page for installation.
You can find more information about NALMS on Confluence, including a description of what NALMS is and how NALMS workflow works. The team is committed to delivering NALMS in the next weeks.

EPLAN and Teamcenter
We're planning to integrate Teamcenter PLM and EPLAN. This integration will bring several advantages, such as improved efficiency by automatically reflecting changes made in EPLAN to Teamcenter, better part tracking through Teamcenter's BOM, improved lifecycle management with a complete view of history provided by Teamcenter, and enhanced document control through specific repositories and tags.
Furthermore, Teamcenter offers a document control that will check all the blocks (check, revision, approval) and then release the drawing in order to have always a complete ad update version. Moreover, after the release, only an official revision can modify the drawing, ensuring consistency of updates.
The Teamcenter admins will ensure that the integration module is updated with EPLAN to maintain compatibility and optimize system performance.
To properly manage Teamcenter content, several tutorials accessible with a Teamcenter license. We'll start getting familiar with the software soon.
Several meetings are scheduled to present the last version of Teamcenter to the ECS group and to start integrating Teamcenter and EPLAN.
