Abstract:

In order to select a suitable absorbing material for cryopump in the nuclear fusion field, one comparison experiment was performed and four candidate coconut activated carbon samples were used. The microstructure of materials was studied with scanning electron microscopy. The adsorption properties of the samples were measured with the specific surface and pore size analyzer, the specific surface area and the pore volume of different pore size were obtained. Based on the comparison results, the suitable samples were found. Some useful information is provided for the coconut activated carbon selection of cryopump in the nuclear fusion field.
