Description
The LCLS-II optical laser delivery system supports many interaction points across many experiment hutches. A modular approach to laser conditioning and delivery has been developed in which various laser modules can be added or removed to a system in order to accommodate a wide range of experiments and requisite laser parameters. Previous iterations of this system have taken an off-board approach where most of the compute and control is done outside of the module. This requires a dense and complex cable patch system and tedious software (re)configuration when switching modules. This has led to low reliability and laborious experiment preparation. In order to increase reliability, reduce reconfiguration time, allow for portable operation, and provide additional capabilities, LCLS is developing an embedded approach in which the majority of the control and compute is done on-module using a powerful embedded system. In this talk, I describe our targeted architecture and efforts towards this embedded approach using commercial System-on-Module (SOM) controllers and custom carrier boards using EPICS and the Yocto build system.
