When the rf plasma parameter is measured using the Langmuire probe，the influence from the plasma potential fluctuations will be a problem. The self-compensated Langmuire probe is one of the methods to overcome this problem. We have suggested that it is effective to use the LC parallel resonance circuit as a high impedance circuit for this probe system. However，there are various difficulties in selecting the circuit elements and their adjustments. As the simple measurement system，we have made several high impedance circuits for this purpose. In this paper，we are going to describe how to make this probe in detail., rfプラズマを測定する際にプラズマ空間電位の時間変動成分からの影響が問題になる。 これを防ぐための方法の一つに自己補償型ラングミュアプローブがある。このプローブに用いられる高インピーダンス回路としてLC並列共振回路を用いることが有効であるが，回路素子の選定及びその調整法には様々な困難がある。我々はこの目的のため単純な測定系として，高いインピーダンスを持つ回路を作製した。そこで今回自己補償型プローブの作製法について詳細に記述する。

An RF tag device is comprised of a spiral coil and a capacitor on a plastic film by a chemical etching technique and has been already used as a resonant marker for detecting shoplifting. It is small and light, so it may be applicable for vehicle navigation and product verification. When the excitation frequency of an electromagnetic wave radiating from an antenna traverses resonance, an electrical ring-down may be generated, so an RF tag device can be easily detected and its resonant frequency can be determined. In this paper I have examined the resonant characteristics and performance of RF tag device to construct the sensing system consisting of the antenna and RF tag devices. And I have shown that RF tag devices can be utilized as a resonant identification for a mobile robot to determine its direction alternatively and to assort several kinds of articles. These examinations have proved RF tag devices to be useful in various areas of factory automation.

One of the SSPS Type is the microwave based power transmission system (M-SSPS), and the unknown phenomenon on M-SSPS is RF Discharge Called by 'Multipactor' and others. In this paper, we describe the test result of RF power Radiation experiment against Solar cell Array for electric power generation on the M-SSPS. Especially, we got very important data between RF radiation power and the RF discharge phenomenon., 資料番号: AA0049500036, レポート番号: JAXA-SP-06-006
