PROGRAM Test of future Service Equipment and Materials: This program has been broken into 2 projects. The first project is accurate location of an Electro Magnetic Pulse Source with stations 300 to 5,000 miles distant. The second is the measurement of the Effects of Atomic Detonations on the Tonosphere. The objective of the first part of this program is to determine ground zero of a release anywhere on the earth by electromagnetic signals originating from a nuclear detonation. As a further requirement, an attempt to obtain yield data by analysis of the pulse will be made. Stations will be located in the Pacific and at various locations in the U.S. The second part of this program (originally program VII which you can see has been scrubbed), is to investigate the physical properties of the ionosphere and what reorientation if any of the earth's magnetic field is occasioned by a MT blast. PROGRAM VIII Thermal Radiation and Effects The purpose here, is to make basic measurements of radiant power as a function of time, and the related effects on various structures materials, aircraft, and machinery. In general these measurements are made by instrumenting panels of differing materials at known distances from ground zero for later analysis, PROGRAM IX General Support: This program includes technical photography from aircraft of the growth and dispersal of the atomic cloud on all MT shots: documentary photography as required by the AEC and DOD; Special
