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.

该提案寻求资金，以升级麦克马斯特大学布罗克豪斯材料研究所的SQUID磁力计的能力。这些升级包括SQUID探针的翻新，最值得注意的是对样品空间周围的真空套管进行了修复，该真空套管在过去30年中已经退化，使得在高于室温的温度下操作不再可行。 除了恢复这一非常需要的能力，我们将增加一个精确的样品旋转能力，使单晶样品可以定向相对于磁力计的外部磁场的高精度。 这种样品旋转能力对于研究高度各向异性材料至关重要，在加拿大将是独一无二的。
