     In the previous paper, the Peltier-cooling-type high performance cloud chamber was introduced, and the notes on the operation, the utilizing method and so on were described. In this paper, it is explained that the technical feature of the hardware which constitutes the Peltier-cooling-type high performance cloud chamber. This product is consisting of very many components that contain technical essence. These technical knowledge are released here so that it may be help for educator and researchers to manufacture the similar equipment or improve this device.

     Waste gases containing radio-isotopes (RI) produced in the synthesis of PET (Positron Emission Tomography) tracers are stored in RI gas storage devices to allow radioactive decay to an acceptable level. Relatively large sizes of the RI gas storage devices, however, prevented us from placing them in a hot-cell (small shielding chamber). In this study, we developed a compact RI gas storage device for placing in a hot-cell, in order to provide a facile means to achieve a safe environment for the synthesis of PET-tracers. We designed our RI gas storage device limiting the number of the usage times a day and optimized the capacity of each component. Consequently, we succeed to downsize the device to W555×D630×H850 mm, which enable us place the device in our hot-cell. A preliminary experiment of synthesizing a 18F-labeled compound proved the capacity of our device to store the RI gases.
