This report delves into the noise issues associated with the AR1BL detector, focusing on clock and data read interference that affects performance. Building on findings from Summer 2004, the investigation emphasizes the critical nature of RF finger connections and highlights the benefits of integrating copper strips and capacitor stuffing to mitigate clock noise. Detailed analysis reveals the noise characteristics over different operational conditions and modifications applied in production versions of the AR1BL. Recommendations for enhancing read timing and reducing extraneous noise are discussed.
