Microwave measurements have proven to be very useful in probing the superconducting state in different types of conductors. This kind of measurement is very important since it can help to eventually identify the physical mechanism leading to superconductivity and to further accelerate their potential technological use. The complex microwave conductivity deduced from these measurements yield a particularly important parameter called the magnetic penetration length whose temperature profile is indicative of the type of physics at work in the materials. My laboratory is dedicated to such measurements in organic superconductors for which the type of superconductivity has not yet been solidly established. Our microwave experiment is very well adapted to these materials at very low temperatures and high magnetic fields. The replacement of an important microwave equipment and an upgrade of the temperature control are the objects of the present proposal.

微波测量已被证明在探测不同类型导体的超导状态方面是非常有用的。这种测量是非常重要的，因为它可以帮助最终确定导致超导的物理机制，并进一步加速其潜在的技术应用。从这些测量中推断出的复杂微波导电性产生了一个特别重要的参数，称为磁穿透长度，其温度分布指示了材料中起作用的物理类型。我的实验室致力于有机超导体的这种测量，因为超导的类型还没有牢固地建立起来。我们的微波实验很好地适应了这些材料在极低温度和高磁场下的工作。更换一个重要的微波设备和升级温度控制是本建议的对象。
