Abstract
A spectrometer was designed and constructed to facilitate measurements of T, T, spin echo signal-to-noise, and resonator quality factor, Q, between about 400 and 1000 MHz. Pulse patterns are generated at 250 MHz and mixed with the output from a second source to perform excitation and detection. A cross-loop resonator was constructed in which the same sample could be measured in the same resonator over the full range of frequencies. An air-core, 4-coil, water-cooled electromagnet with a large experimental volume was built.
摘要
设计并制造了一台光谱仪，以方便在约400至1000兆赫兹之间测量T、T、自旋回波信噪比和谐振器品质因数Q。在250兆赫兹下生成脉冲模式，并与第二个源的输出混合，以进行激发和检测。构建了一个交叉环谐振器，在该谐振器中，可以在整个频率范围内的同一谐振器中测量同一样品。制造了一个具有大实验体积的空心、4线圈、水冷电磁铁。
