1Abstract Plasma turbulence measurements play a crucial role in understanding transport, which affects the fusion yield of tokamaks. However, there is a notable scarcity of plasma turbulence diagnostics, particularly temperature fluctuations. While soft x-ray (SXR) imaging holds promise for measuring electron temperature fluctuations, such a fluctuation diagnostic has not yet been developed. In our prior work (Chen et al 2021 Rev. Sci. Instrum. 92 055337), we successfully designed an SXR-based el
