Report discussing the results of a series of tests in Galveston Bay to: "(a) develop plans for relocation and stabilization of the jetty channel on an alignment and at a depth suitable fro the safe passage of supertankers; (b) determine means for protecting the north jetty from the undermining action of tidal currents; (c) determine the shoaling characteristics of the relocated and deepened jetty (inner bar) channel and develop plans for minimizing shoaling in the relocated channel; and (d) determine the best locations for additional anchorage areas adjacent to the jetty channel or in Bolivar Roads" (p. ix).

A FORTRAN IV program to represent experimental thermal data with orthogonal functions and to tabulate the thermodynamic functions is described. The use of a more general algorithm permits the generation of power series which can contain positive or negative powers. Further, it is possible to start generation at any power with any term-to-term increment in the exponent. This allows the use of an equation with a leading cubic term for very low temperature heat capacities. Enthalphy data can be approximated with a leading reciprocal temperature term. Appropriate coding allows analytical generation of the thermodynamic functions. The methods of combining thermal data are reviewed and discussed. The program combines any number of heat capacity and/or enthalpy segments (from formats logically selected at the time of execution) in order to generate a complete tabulation presented in rounded, directly publishable form.

Two beam choppers were constructed which produce an approximately square, 20-ns pulse of 3+-MeV electrons out of the best portion of the 300-ns Astron beam or an 8-{micro}s microwave electron linac beam for injection into the electron-ring accelerator (ERA) compressor. The choppers are impedance-matched traveling-wave devices which deflect the beam with equal strength electric and magnetic forces, and are powered with either three-electrode spark gaps or thyratrons and a 20-ns pulse line. The electron beam is biased out of the beam-transport system with a dc magnetic field, and switched into it with the chopper.
