超导带状线探测器（SSLDs）是有前途的检测千电子伏的分子在纳秒响应时间和质量无关的检测效率。然而，快速响应时间与实际厘米探测器尺寸不兼容。带状线的并行配置提供了解决这个问题的方法。实验结果和模拟的有前途的大1平方毫米的平行铌固态激光器表明，纳秒脉冲产生的超导正常过渡内只有一个平行带状线，而不是级联开关的所有平行带状线。一系列高达584 kDa的免疫球蛋白G多聚体的成功检测支持质谱的质量独立效率。
Superconducting stripline detectors (SSLDs) are promising for detecting keV molecules at nanosecond response times and with mass-independent detection efficiency. However, a fast response time is incompatible with practical centimeter detector size. A parallel configuration of striplines provides a means to address this problem. Experimental results and simulation for promisingly large 1-mm-square parallel niobium SSLDs show that nanosecond pulses are produced by superconducting-normal transition within only one of the parallel striplines instead of cascade switching of all the parallel striplines. Successful detection of a series of multimers of immunoglobulin G up to 584 kDa supports the mass-independent efficiency for mass spectrometry.
