Description

The LCLS began operations in 2009, utilizing SLAC's normal-conducting LINAC, which features control equipment dating back to the 1960s and 1980s. The Linac Electronics Modernization Plan (LEMP) aims to replace the legacy control equipment with a system based on the open-source Marble carrier board and a modified version of the Zest digitizer board, both of which are used in the LCLS-II HE LLRF system. Adaptation of the LLRF system from the CW SRF LCLS-II to the short RF pulse NC LCLS includes leveraging the knowledge and experience gained from recent LLRF projects at SLAC and efficiently reusing the core functionality of the code base developed at LBNL. Here, we describe the firmware and software infrastructure, highlight key features, and present initial test results.
