The theoretical portion of this report reviews the equations for steady electron flow of an ideal laminar beam under conditions of crossed electric and magnetic fields, taking account space charge in the beam and also the presence of a sole which is negative with respect to the cathode. Cold tests have been made on a full-scale line deposited on sapphire, and also on an S-band line deposited on bakelite. Measurements of propagation, attenuation, and matching are being made in S-band considering both symmetrical and anti-symmetrical modes. Beam test measurements of the optics have been made at full scale to check the performance of the emitter and of the gun, and to compare these results with calculations. Further, the transmission of the beam has been measured and the power which reaches the collector has been measured by means of a water calorimeter. The technological part of the work has been concerned with the brazing of the sapphire support of the delay line onto a block for water cooling without supports liable to cause breakage or to deformation of the sapphire. It appears that alumina allows brazing in spite of negative results of tests.
