A beam diagnostics system is vitally important to operate all accelerator-based facilities. The system provides information about beam characteristics and enables requested beam parameters to be achieved. The main parameters, such as beam energy, current, emittance, and beam position, must be diagnosed and controlled during the operation of an accelerator. Beam position monitors (BPMs) are an essential tool for diagnosing a system of accelerators. They are used to define the position of the beam traversing through the beam pipe at relativistic speed. These tools can be used to achieve the required beam quality as well as protecting the entire system against any beam loss or radiation damage. In this study, we present the bases of BPM front-end electronics designed for the Turkish accelerator and radiation laboratory (TARLA) facility, which is a linear electron accelerator proposed to drive a free electron laser.
