For about a year, the MIT-ONR Van de Graaff generator has been in operation. It is capable of accelerating charged particles to energies of about 8.5 Mev and of supplying beam currents of about 0.3 Microampere. The generator accelerates the particles vertically downward into a deflecting magnet which acts as a momentum filter and deflects the beam, particles through 90 degrees. The particle beam then travels horizontally through a collimating slit system to impinge upon a thin target* The energy spectrum of the product particles emerging at 90 degrees to the incident beam is analyzed by means of an annular magnetic spectrograph which employs 18O-degree focusing. The particles are detected by observing the tracks made on nuclear emulsions. The tracks are counted under a microscope; the number of particles is plotted versus diameter of curvature; and from these plots, the energies of the particle groups are computed. The energy of the incident particles is determined by measuring their deflection after they have been elastically scattered from a known target nucleus.
