From abstract: "The motion of a charged particle in a region of crossed electric and magnetic fields is discussed... Possible applications of such a system to various problems in nuclear research are suggested and it is shown to be possible in principle to measure the kinetic energy, mass, and ionic charge of various nuclear-reaction products and to separate various short-lived products for rapid examination. Two different devices are proposed. The application of the technique to investigation of the fission process is specifically discussed."

The following report is a general monthly progress report conducted by the radiation laboratory of the University of California discussing experimental physics, theoretical physics, the MTA target physics program, accelerator construction and operation, biology and medicine, and a plant and equipment report. The period being covered is January 15, 1954 to February 15, 1954.
