AUTOMATION OF DATA ACQUISITION TO HANDLE SEVERAL SAMPLES SIMULTANEOUSLY

这个子项目是利用资源的许多研究子项目之一。 由NIH/NCRR资助的中心拨款提供。对子项目的主要支持 子项目的首席调查员可能是由其他来源提供的， 包括美国国立卫生研究院的其他来源。为子项目列出的总成本可能 表示该子项目使用的中心基础设施的估计数量， 不是由NCRR赠款提供给次级项目或次级项目工作人员的直接资金。 这个子项目(阶段5)是最具挑战性的项目，准备进一步开发多样品探头，以便实现高速样品切换，我们称之为以“循环”方式处理样品。对于这一开发，我们有标准(50-60K)和低(8-20K)温度范围的概念性解决方案。第二个温度范围对于将探头与低温接收器集成也很有吸引力。在成功实施这种类型的探测器的情况下，我们将把它与低温接收器集成在一起。多样品探头的开发是该项目中最具挑战性的方面，需要进行大量研究，包括但不限于“接通”或多通道微波接收器、控制和DSP软件、低温接收器保护器和其他关键部件的开发。涉及的技术包括相当高的高精度加工，硬材料研磨和抛光到高精度，制造微波组件和真空部件，以及电子电路。成功完成需要获得合适的工程资源，我们在Acert(特别是Boris Naumov)拥有部分资源，我们将根据需要外包给美国公司。总体而言，该项目虽然在技术上非常具有挑战性，但需要以合理的成本实现可实现的目标。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. This subproject (phase 5) is the most challenging one, poised to further develop the multi-sample probe in order to enable high-speed sample switching, which we refer to as processing them in a "round-robin" fashion. For this development we have conceptual solutions for both standard (50-60K) and low (8-20K) temperature ranges. The second temperature range is also attractive for integrating the probe with a cryogenic receiver. In the case of successful implementation of such type of a probe we shall integrate it with a cryogenic receiver. The development of the multi-sample probe is the most challenging aspect of the project requiring substantial research, including but not limited to the development of a "set-on" or else multi-channel microwave receiver, control and DSP software, cryogenic receiver protector, and other key parts. The technology involved encompasses considerable high-precision machining, hard material grinding and polishing to high accuracy, fabricating microwave assemblies and vacuum parts, and electronic circuits. The successful completion requires access to suitable engineering resources, which we have in part at ACERT (in particular Boris Naumov), and we will outsource to U.S. companies, as needed. Overall, the project though technically very challenging, entails achievable goals at reasonable cost.
