A general discussion of the proposed program was held and several changes to the initial. proposal. H \were made.. The power supply will be operated. from .the mains with inputs.of.115. 160. 220 Vac ±15%, 48-62 cps. The need for a specially wound transformer will be ofrset by the elimination of battery supply and.recharger.

The need for ±1/2 dB accuracy rather than ±3 dB was accepted as a goal with the understanding that.we would accept a 1 to 10 Gc/s frequency responçe yice 1-40 Gc/sif the requested accuracy.could be achieved. A determination of ultimate acouracy cannot .be made.unsil further theoretical work is accomplished: -However, the estimate of ±3 dB was made on the bas1s.of hand solutions of rather complex equations. Since that time the equations have.been solved by computer and' the datà 1s in the process'of being analyzed.

The 1000 mw/cm² range will be included with only roúgh calibration, most likely at one or two selected power levels in the lower part of the range. The desire for long.term accuracy, stability and reliability'led to consideration of an automatic calibration system such that the sensor system would .be rebalanced before every reading. This type of calibration feature will be investigated early in the progran.

The problem of packaging for shipment was explored with special attention being paid to the protective dome around the sensor. It was agreed that the best solution was to Bupply the contractor with two of the special State Dept. shipping containers, for actual tests late in the program.. #.

SUBJECT: Health Hazard Radiometer (RAM), Contract Negotiations

The program maneger, Mr.Eesznz was informed that both Meosrs. Charles-J. Weiss and Theodore H. Vea, State Dept.. were to have complete access to program data when and if they visit the plant. Further, that in the event any other individual accompanies those named above, Messrs. lieiss and Vea: have the personal authority to vouch for the individual.

During actual negotiations, G&A was redoced by 2% and profit by 1% bringing the negotiated cPpp contract price toauamaWhile the contract document will not be ready for approximately three wees, the effective contract initiation date wi11 be 28 September 1965. Based on Mr.sverbal intent to contract, although not legally binding. The first monthly report 1s due 15 November 1965.
