The MaRIE 1.0 X-FEL requires an electron beam at 12 GeV with 100pC bunch charge, 0.2 μm RMS normalized transverse emittance, and 0.15% RMS slice energy spread. These requirements place significant constraints upon the use of techniques, such as laser heaters, which have enabled other X-FELs to reach their design goals. In this paper, we present the current baseline design and performance of the MaRIE 1.0 linac, highlight current and anticipated challenges and describe potential alternate approaches for meeting our design performance goals.
