我们介绍了新型测热探测器阵列的电学和热学性能的测量结果，这些测热探测器阵列是为了开发针对EBEX气球载实验低光子背景优化的测热仪而制造的。该阵列由140个蜘蛛网过渡边缘传感器热辐射计组成，这些热辐射计被微加工在直径为4英寸的硅片上。在原型阵列上设计的辐射热计的平均热导率（见手稿）为32 pW/K，测量结果与该值吻合良好。测量采用新开发的数字频域多路复用器SQUID读出电子器件。
We present measurements of the electrical and thermal properties of new arrays of bolometeric detectors that were fabricated as part of a program to develop bolometers optimized for the low photon background of the EBEX balloon-borne experiment. An array consists of 140 spider-web transition edge sensor bolometers microfabricated on a 4" diameter silicon wafer. The designed average thermal conductance (see manuscript) of bolometers on a proto-type array is 32 pW/K, and measurements are in good agreement with this value. The measurements are taken with newly developed, digital frequency domain multiplexer SQUID readout electronics.
