Description

In this paper, the low cost gap switch was created for small student experiments. As a result, the gap switch with a fall time of about 3.6 μs was created. And low voltage discharge experiments at 20 V was observed chattering in about 1.5 ms cycle. Regarding the chattering, it is assumed that there is no major problem. When a high voltage is applied, it is expected that a discharge will occur before the ball gaps come into contact with each other and that the gaps will be short-circuited by plasma. At this time, it is considered that the discharge is not extinguished because the large current is flowing. From these facts, this gap switch has sufficient turn on speed and pulsed rise times, it is considered to endure practical use. Therefore, it is considered that the low cost gap switch for small student experiments made in this paper can be fully used. In the future, it is considered that it is necessary for practical use to experiment which applied high voltage.
