稀释制冷机的相边界检测

Phase boundary detection for dilution refrigerators

E. ter Haar, R. V. Martin

摘要:

我们描述了一种装置,以方便地测量相界的稀释冰箱中的位置。我们展示了如何一个简单的修改标准的电容液位计(分割的电极之一)允许直接校准的电容与相位边界位置。我们比较了这种直接校准与间接的程序,必须采用传统的电容液位计。该装置有助于稀释冰箱中3 He/4 He分数的正确调节。

英文摘要:

We describe a device to conveniently measure the positions of the phase boundaries in a dilution refrigerator. We show how a simple modification of a standard capacitive level gauge (segmentation of one of the electrodes) permits a direct calibration of the capacitance versus phase boundary position. We compare this direct calibration with the indirect procedure that must be adopted for a conventional capacitive level gauge. The device facilitates the correct adjustment of the 3He/4He fraction in the dilution refrigerator.
