TI - Front End Concept for a Wake Field Monitor J2 - Proc. of IBIC2014 AB - Wake field monitors (WFMs) are used to directly measure the alignment between beam and RF accelerating structure via the transverse higher mode spectrum. As a sub task of the EuCARD2 project, we are developing a front end for the monitors of the multipurpose X band structure installed at the SwissFEL Injector Test facility SITF at PSI. We plan to use electro optical technology offering strong advantages in the robustness to interference and radiation, and in the ease of signal transport. We present the concept of the device, discuss the theoretical performance in terms of noise. For a proof of principle, we built a basic system, which we tested together with the existing monitors with beam at SITF.
