It can continuously and steadily observe paths characteristics of high speed electrically charged particles for long-term without dry ice agent and dynamic operation. It is used to observe basic particle track in physics teaching of lecturing nuclear structure, it is necessary demonstration instrument for secondary school and can be used for students’ grouping experiment in colleges and universities.
