# | Item | Who | Notes |
---|
1 | Laser System Procedural Documentation | Jason Bender | - LLE to develop an operational procedure document for HE-LP laser system.
- From here, we will develop interfaces to subsystems.
|
2 | LLE Device List | Jason Bender | - Hardware device list will be collaborative as some systems will come entirely from SLAC (Motion, timing, laser safety) and some are custom for LLE
- New/custom devices will need EPICS interface developed.
|
3 | LLE ICD | Jason Bender |
|
3.1 | Shot Executive | Jason Bender | - SLAC to develop shot executive code based on LLE design.
- It is vital to see how the shot process functions in order to understand how form code.
- November 11-15, Diana will show Tyler J and Alex W how the shot process is performed from the controls POV.
|
3.1.1 | Code Development | Jing Yin | - Jing requested use cases to understand software/code more in depth.
- LLE is currently determining how much source code should be shared with SLAC.
- LLE to find documentation of shot executive and facility operations to show how different systems are communicating with one another.
- Previous presentation addressing overall architecture. Jason to resend presentation to SLAC.

3.2 | Power Conditioning Unit | Jason Bender | |
3.3 | Laser Safety System | Jason Bender | |
3.4 | Pulse Shape Control and Measurement | Jason Bender | |
3.5 | Laser Timing Manager | Jason Bender | |
3.6 | Hardware Timing System | Jason Bender | |
3.7 | TDC Time to Digital Converter | Jason Bender | |
3.8 | Motion Control | Jason Bender | |
3.9 | Digital Imaging | Jason Bender | - LLE has collection of cameras they use. Will check SLAC supported device list.
|
3.10 | Energy Diagnostics | Jason Bender | |
3.11 | Calorimeters | Jason Bender | - LLE has calorimeters that they have. Will share devices.
|
3.12 | Spectrometer | Jason Bender | |
3.13 | Regen/preamp Injection Pump and Wavefront Controller | Jason Bender | |
3.14 | Plasma Electrode Pockets Cell (PEPC) | Jason Bender | |
3.15 | Vacuum System | Jason Bender | - Similar beckhoff systems, SLAC.
|
4 | Creating Device Lists | Jason Bender | - Device counts not needed at this level.
- Need to identify the various device classes. Everything that needs to be replaced with a SLAC solution needs to be identified.
- Iterative and collaborative process of forming the device lists where LLE will create an initial list for all definite non-SLAC ICD devices to be used. All systems that are SLAC-owned will be filled by SLAC.
|
5 | Sharing Documentation | Jing Yin | - Jing to ensure Jason is on SharePoint and can post the LLE ICD there.
|
6 | Weekly meetings | Jing Yin | - Weekly LLE/SLAC meetings every Tuesday.
|
7 | Roadmap for MECU (SLAC) | Jing Yin | - Current goal to expand control architecture.
- We need to provide support to LLE to adapt to LCLS architecture.
- LLE Laser System PDR coming soon. We need to help them adapt to LCLS architecture and identify what SLAC systems LLE cannot use.
- We are unsure of the responsible parties for EPICS development of new systems and how much this effort will be.
- The near goal is to push out the LLE ICD, identify gaps that do not support their needs, and negotiate how this will be sorted out.
- We are confident that any additional devices that need EPICS integration will not cause issues as long as they are recommended by SLAC.
- For this stage of the project, we want to ensure that we have a clear path forward for integration.
- MECU design to start in November.
