@Dai W, Matsubara Y. and Kobayashi H.

　 Ever since last meeting, V-M pulse tube refrigerator has been much improved. We changed the configuration method and re-designed regenerator sizes. Now the lowest temperature is below 8K with high to low pressure ratio being 1.2. In this article, details of experimental result will be given.
