In order to better understand the processes behind nuclear fusion, high precision and reliable diagnostics are required. Traditionally, analogue diagnostics have been used, mostly due to cost and availability. Analogue electronics take up a large volume and often have to be completely redesigned when moving to different systems or making changes to their function. In recent decades, huge advancements in digital technology has made the use of digital systems more affordable and more robust. The Field Programmable Gate Array (FPGA) can provide a low-cost and modular solution to the analogue problem.This thesis will describe the designing, implementation and testing of a new diagnostic for future installation onto Mega Amp Spherical Tokamak - Upgrade (MASTU), the Ultra Fast Langmuir Probe (UFLP). The UFLP aims to solve the Langmuir equation in real time utilising only a single Langmuir probe configuration to return the electron temperature, ion saturation current and plasma floating potential. It achieves this via fast biasing and dynamic adjustment of the bias range to ensure samples are taken within the transition region. The design of such a system both in terms of FPGA design and electrical hardware will be described. To ensure properly functionality, real-world testing results in low temperature magnetron systems will be presented.
