对于下一代宇宙微波背景(CMB)实验来说,要达到所需的灵敏度和科学目标,需要千像素的过渡边缘传感器(TES)热辐射计阵列。我们正在开发用于POLARBEAR-2 CMB实验的读出电子设备,该实验通过单个超导量子接口器件(SQUID)复用32-TES热辐射计。为了提高SQUID电子器件的带宽和复用系数,我们正在改进冷接线,开发LC滤波器和低电感超导电缆。使用这些组件,我们将展示高达3mhz的频域复用。
For the next generation of Cosmic Microwave Background (CMB) experiments, kilopixel arrays of Transition Edge Sensor (TES) bolometers are necessary to achieve the required sensitivity and their science goals. We are developing read-out electronics for POLARBEAR-2 CMB experiment, which multiplexes 32-TES bolometers through a single superconducting quantum interface device (SQUID). To increase both the bandwidth of the SQUID electronics and the multiplexing factor, we are modifying cold wiring and developing LC filters, and a low-inductance superconducting cable. Using these components, we will show frequency domain multiplexing up to 3 MHz.
