Professor / Weihua JIANG
An authoritative professor in the fields of plasma science and electric power engineering, specialised in pulsed power.He was awarded the Fellow for the IEEE in January 2014.He is very friendly,and after getting along with him, we can learn not only his professional knowledge, but also his rigorous attitude to science and unique way of thinking.

Research Content

Pulsed power technology can obtain a ralatively large intantaneous output by using constant energy in a very short time which can be widely used in fields such as accelerator,environment and biology. In our laboratory,we developed and manufactured compact devices of LTD,Marx,SOS circuits and other devices for the applyment of water treatment,ozone generator,sterlization and so on.In addition,we are investigating to improve the output of high power microwave using high repetition power generator‘ETIGO-IV'.It is an unusal laboratory ,because there is no other labaratory doing such research in Japan.

A Day in the Lab

One day begins by watching news in English while dringking coffee,which helps a lot in improving English levels.Then we carry out our own experiment or organize data and prepare materials for the weekly process report.We can arrange our time flexibly to read the references recommended by professor and study English or others.Besides,a lot of events are held in our laboratory, large number of students and professors paticipate in them,such as Ohanami in April, Softball Match in June, Nagaoka Firewoks Festival in August and Mountain Climbing in October.It is a well-balanced and happy laboratory for us in which we study hard and have fun.
