Repair and Upgrading of SQUID Magnetometer

这项提案寻求资金来升级麦克马斯特大学布罗克豪斯材料研究所的鱿鱼磁强计的能力。这些升级包括翻新鱿鱼探头，最引人注目的是修复样品空间周围的真空套筒，该套筒在过去30年里已经退化，因此在高于室温的温度下操作不再可行。除了恢复这种非常需要的能力外，我们还将增加精确的样品旋转功能，以便单晶样品可以相对于磁强计的外部磁场进行高精度定位。这种样品旋转能力对于高度各向异性材料的研究至关重要，在加拿大将是独一无二的。

This proposal seeks funds to upgrade the capabilities of a SQUID magnetometer housed in McMaster University's Brockhouse Institute for Materials Research. These upgrades include a refurbishment of the SQUID probe, most notably a repair of the vacuum sleeve surrounding the sample space which has degraded over the past 30 years such that operation at temperatures above room temperature is no longer feasible. In addition to restoring this much demanded capability, we will add a precise sample rotation capability so that single crystal specimens can be oriented with high precision with respect to the external magnetic field of the magnetometer. This sample rotation capability is critically important for the study of highly anisotropic materials and will be unique in Canada.
