Measuring the noise floor of Hybrid Quantum Interference Devices

约克仪器的主要产品是MEGSCAN：下一代脑磁图（MEG）脑部扫描仪，提供非侵入性功能性脑成像，具有广泛的临床用途，包括与癫痫，脑震荡和肿瘤学相关的应用。MEGSCAN系统的核心是一种新型的磁传感器，称为混合量子干涉装置（HyQUID）。HyQUIDs是一种超导磁强计，与传统的磁强计相比，HyQUIDs具有更低的噪声和更高的灵敏度。在这里，约克仪器将与国家物理实验室（NPL）密切合作，建立一个新的测量平台，用它来验证性能（HyQUID噪声底）。这将导致对传感器的进一步理解和迭代优化，以提供最佳性能，并最终提高约克仪器MEGSCAN系统的诊断能力。

York Instruments' main product is MEGSCAN: a next-generation magnetoencephalography (MEG) brain scanner which offers non-invasive functional brain imaging with wide clinical utility including applications relating to epilepsy, concussions, and oncology. At the heart of the MEGSCAN system is new type of magnetic sensor, called the Hybrid Quantum Interference Device (HyQUID). HyQUIDs are superconducting magnetometers that are expected to have lower noise and higher sensitivity than the magnetometers traditionally used in MEG systems. Here, York Instruments will work closely with the National Physical Laboratory (NPL) to build a novel measurement platform with which the performance (HyQUID noise floor) will be verified. This will lead to further understanding and iterative optimisation of the sensor to provide best performance and ultimately improved diagnostic capability of the York Instruments MEGSCAN system.
