Institute of Electronic Systems (ISE) at Warsaw University of Technology designs, builds and installs control and synchronization systems for several accelerator facilities. In recent years ISE together with the Deutsches Elektronen-Synchrotron (DESY) team created the RF synchronization system for the European XFEL in Hamburg. ISE is a key partner in several other projects for DESY flagship facilities. The group participated in development of the MTCA.4 standard and designed a family of components for the MTCA.4-based LLRF control system. Currently, ISE contributes to the development of the Master Oscillators for XFEL and FLASH, and phase reference distribution system for SINBAD. Since 2016 ISE is an in-kind partner for the European Spallation Source (ESS), working on the phase reference line for the ESS linac, components for 704.42 MHz LLRF control system, including a MTCA.4-based LO signal generation module and the Cavity Simulator. In 2019 ISE became one of the co-founders of the Polish Free-Electron Laser (PolFel) located in the National Centre for Nuclear Research in Świerk. The overview of the recent projects for large physics experiments ongoing at ISE is presented.

This paper describes the specifications, architecture, and measurements’ results of the MTCA-compliant Local Oscillator (LO) Rear Transition Module (RTM) board providing low phase noise clock and heterodyne signals for the 704.42 MHz Low Level Radio Frequency (LLRF) control system at the European Spallation Source (ESS). The clock generation and LO synthesis circuits are based on the module presented at ICALEPCS 2017. The conditioning circuits for the input and output signals must simultaneously achieve the desired impedance matching, spectral purity, output power as well as the phase noise requirements. The reference conditioning circuit presents an additional challenge due to input power range being significantly wider than the output range. The circuits monitoring the power levels of critical signals and voltages of supply rails for remote diagnostics as well as the programmable logic devices used to set the operating parameters via Zone3 connector are described.
