Drawing: 101-002-C6 POST -GO PROCUREMENT To be accomplished. CONSTRUCTION Test Command will furnish the following equipment: a) ifa central power plant is not planned; one 30 kw, 120/240 volt, 60 cycle, 3 phase generator; b) one 40-ft. instrument trailer; and c) one light sensor. The contractor will perform the following: a) prepare a site location as far as possible from transmitters and Subtasks A605, A611, and A628; b) drill two 4 1/2-in. diameter cased holes with the bottom 10-ft. (minimum) of the casing cemented. The holes should have a 6 to 12-ft. horizontal separation and the depths should differ by 100-ft. (+ 1 foot). The shallower hole will have a minimum depth of 20-ft. The holes should be drilled in rock or coral of uniform density; c) locate the instrument trailer antenna so as to have a line-of-sight to all events and at a minimum of 100-ft. from the cased holes; and, d) pro- vide electrical hookup where required. The project manager, USAF/ESD will determine the need and a site location for Subtask A629 ata later date. Refer to Figure A-22, Appendix A, for possible site location. Three scientific personnel will be assigned to Subtask A629 at this location. 25-8 GG VOL II April 1969
