This proposal requests the procurement of three pieces of equipment1. A three axis 1m Helmholtz calibration coil system with dynamic Earth's field compensation. This will be used for enhanced screening of emerging magnetic sensor technologies and magnetometer calibration, at present something we can only perform at external facilities. The system is off the shelf and includes a power amplifier and electronics control system.2. Bespoke three-layer magnetic shielding tank manufactured from a special cryo-compatible mu-metal. It will be used during sensor thermal vacuum testing and its purpose is to enable the characterization of magnetic sensor performance in fully representative thermal space conditions on ground. 3. Network analyser. This is an off the shelf instrument that measures impedance across a wide frequency range. It will be used to measure the impedance of magnetic sensor and power converter control loops with the aim of increasing the measurement bandwidth of our magnetometers beyond their existing low frequency/DC range. Each piece of equipment adds a new and distinct test capability to our laboratory and all of them will enable performance improvements in our space magnetometers.

这项建议要求采购三台设备。具有动态地磁场补偿的三轴1m亥姆霍兹校准线圈系统。这将用于加强新兴磁传感器技术的筛选和磁力计校准，目前我们只能在外部设施进行。该系统是现成的，包括一个功率放大器和电子控制系统。定制的三层磁屏蔽罐由特殊的低温兼容金属制造。它将用于传感器热真空测试，其目的是在地面上完全具有代表性的热空间条件下表征磁传感器的性能。3. 网络分析器。这是一种现成的仪器，可以测量宽频率范围内的阻抗。它将用于测量磁传感器和功率转换器控制回路的阻抗，目的是增加我们的磁力计的测量带宽，超出其现有的低频/直流范围。每一件设备都为我们的实验室增加了一个新的和独特的测试能力，所有这些都将使我们的空间磁力计的性能得到改善。
