Joint research on a technique of LODERS imaging.

虽然纵向探测电子自旋共振(LODESR)方法的成像是一项正在发展中的技术，但积极研究LODESR方法的机构只有我们研究所和阿伯丁大学。在本研究中，这些研究所联合开展了LODESR方法的研究。我们所取得的成果是：(1)用于高灵敏度探测LODESR信号的多层元件谐振器；(2)用于脉冲技术的高功率低Q射频谐振器；(3)用于大范围低场测量的LODESR磁强计。另一方面，在阿伯丁大学，(4)发展了一种LODESR分析技术，作为检测频率的函数。作为联合研究的结果，(5)发展了一种在不同间隔的π脉冲下的脉冲电子自旋共振测量方法。这也是应用(2)的结果，并且使得确定纵向松弛时间成为可能。测量弛豫时间是一种很好地利用LODESR特性的方法。

Although imaging by longitudinally detected electron spin resonance (LODESR) method is a developing technique, institutes where the LODESR method has been actively researched are only our institute and University of Aberdeen. In this study, the joint research of the LODESR method was performed by these institutes. The results in our institute are development of, (1) a mutilayered element resonator for highly sensitive detection of LODESR signal, (2) a high-power low-Q RF resonator for pulse techniques, and (3) a LODESR magnetometer for wide range measurements of low fields. On the other hand, in University of Aberdeen, (4) a LODESR analyzing technique as a function of detecting frequency was developed. As a result of the joint research, (5) a pulsed LODESR measuring method at various intervals of π-pulses was developed. This is also a result of an application of (2), and makes it possible to determine longitudinal relaxation times. Measuring relaxation times is a method where the characteristics of LODESR are well utilized.
