چکیده انگلیسی
Topmetal-IIâ is a highly pixelated direct charge sensor that contains a 72Ã72 pixel array of 83 μm pitch size. The key feature of Topmetal-IIâ is that it can directly collect charges via metal nodes of each pixel to form two-dimensional images of charge cloud distributions. Topmetal-IIâ was proved to measure charged particles without amplification at room temperature. To measure its performance at cryogenic temperature, a Topmetal-IIâ sensor is embedded into a liquid nitrogen dewar. The results presented in this paper show that Topmetal-IIâ can also operate well at this low temperature with a noise (ENC) of 12 eâ lower than that at room temperature (13 eâ). From the noise perspective, Topmetal-IIâ is a promising candidate for the next generation readout of liquid argon and xenon time projection chamber (TPC) used in experiments searching for neutrinoless double beta decay and dark matter.
