Abstract

A copper X-band (9.22 GHz) cross loop resonator has been constructed for use with 4 mm sample tubes. The Q for the two resonators are 380 and 350, respectively. The resonator efficiency is about 1 G per square root of watt. Operation has been demonstrated with measurement of T by saturation recovery for samples of coal and an immobilized nitroxide radical.

摘要

已构建了一个用于4毫米样品管的铜制X波段（9.22吉赫兹）交叉环形谐振器。两个谐振器的品质因数分别为380和350。谐振器效率约为每瓦特平方根1吉。通过对煤样品和固定化氮氧化物自由基进行饱和恢复测量T，已证明了该操作。
