Outline of Final Research Achievements

As an idea to solve the problems of the liquid argon detector, we study on the possibility of "gas amplification by rare gas microbubbles in liquid argon". We planned a cosmic ray experiment by a test stand with the simple structure without a liquefier device and computer simulation.
The simple test detector system was designed and developed with the aim of running for about 24 hours without a liquefier device. We were able to demonstrate the possibility of operation for about 24 hours by refilling with liquid nitrogen. The experiment could not be performed due to problems of the neon gas circulation etc, but each part of the test detector system was designed, developed, and confirmed. In the process, I found a new idea on the method of mixing neon gas in argon.
