A study of computerized tomography is made for the purpose of reconstructing the ion velocity distribution function of plasma in the three-dimensional velocity space. A conventional type of ion energy analyzer with retarding grids is rotated in a plasma in order to acquire the data to be processed. Experimental results are presented on an argon plasma with a low-energy ion beam, which is generated in a double-plasma machine.
