As a next-generation tonne scale double beta decay experiment, nEXO requires new development in detector technology. One key area is the development of low noise front-end electronics that can operate directly in liquid xenon (~170 K). In collaboration with the Brookhaven National Lab, students Shaolei Li and Xuanying Li are testing the performance of prototype boards built with custom ASICs. In the coming weeks, they will develop codes to readout all channels of the board and analyze the noise correlation between different channels. The board will later be used in liquid xenon test setups by the collaboration.
