Richard Connor, left, High Voltage Engineering, and Thomas Hubbard, of Well Surveys, compare size of laboratory particle accelerator with newly-developed "baby" one, both built by High Voltage. The larger unit, 4 ft. in diameter and 6 ft. long, dwarfs the smaller neutron generator, 3 in. in diameter; 47 in. long
Further development of this type of equipment represents the only known scientific approach to the eventual posi tive identification and location of oil at great depths, in new/ or existing bore holes, a long-sought goal of oil men everywhere, says High Voltage. • Status of New Generator. Ac cording to John J, Buck, vice president and technical director of Well Surveys, a basic initial decision was made b y his company and High Voltage t o aim their joint efforts direcdy at the ulti mate goal of perfecting equipment small enough and reliable enough t o meet well-logging demands in the oil industry, as opposed to a step-by-step development. "We knew that approach would take longer in the earlier phases, but felt that time would be saved i n the long run. N o w we're glad we chose it," Buck asserted. Although preliminary tests with the accelerator have already been run i n the Well Surveys' test well at Tulsa, Okla., an intensive test program for both the neutron source and accom panying instrumentation will be ac celerated through the coming months, according to Buck. "Naturally, every effort will be made by both companies to hasten the availability of this ad vanced logging method to the oil in dustry generally," he concluded. Ε1

"BABY" ACCELERATOR is helping
to
push radioactivity well logging several strides closer to positive identification and location of oil-bearing formation, according to its manufacturer, High Voltage Engineering. The new unit is a miniature version of a Van de Graaf particle accelerator, a large radiationgenerating machine recently adapted for chemical processing and steriliza tion. The miniature neutron generator, in corporated in a standard 3 5 / s hi. well logging assembly, is itself only 3 in. in diameter and 47 in. long. Yet, ac cording t o High Voltage Engineering, the "baby" Van de Graaf generates electrical potentials up to 200,000 volts. For the purpose of radioactive well logging, complex instrumentation that is used with the neutron source has been developed b y Well Surveys' scientists and engineers. Also Well Surveys, an affiliate of Lane-Wells, has perfected the "baby" accelerator for oil field problems. Recently, Well Surveys ran its first successful field 5430

test with the accelerator in locating and identifying oil-bearing formations. • How Accelerator Operates. The Van de Graaf generates electrical po tentials used to produce a stream of deuterons. These are fired into a target of tritium. The collision of deuterons with tritium atoms produce an intense yield of neutrons. The neutrons penetrate the earth's formations surrounding a bore-hole and cause various nuclear reactions in the material encountered. These reactions, in turn, yield atomic particles and rays. These are identified and measured by radiation detection equipment which accompanies the accelerator down the hole. According to High Voltage, the re sulting information, transmitted to the surface and recorded, when correlated with the results of neutron radiation research performed with a large halfmillion volt accelerator in Well Sur veys' laboratories, will be extremely useful in the identification and evalua tion of formation constituents.
For closed-circuit TV installations, Thompson Products has designed a multi-lens TV camera which is con trolled by a separate monitor-console. According to the company, lenses o n the camera are changed, focusing is set, and the camera is directed up or down, right or left, all by remote control. This is achieved by a "servo pan and tilt" system developed b y Thompson Products. There are three "preset" pan and tilt positions in the console which can be selected by pushing a button; turn ing an appropriate knob permits manual control. Company says the preset posi tions may be readily changed.

An x-ray spectrometer, designed by General Electric engineers at the AEC's fïanford plutonium plant, is claimed to detect changes as small as a billionth of an inch in the distance between crystal facets. Checking unit are its developers (left to r i g h t ) , M. J. Sanderson, D. C. Kaulitz, and W. V. Cummings, G E engineers. Unit is used to measure submicroscopic damage suffered by solids exposed to chain reaction heat a n d radiation in an atomic pile. Object is to a i d in finding new atomic furnace elements that will stand u p longer. A beam of x-rays is shot by the device at specimens of highly radioactive uranium and other materials. A Geiger counter measures the strength of the reflected beam. T h e angular distribution of these x-rays tells how much the specimen's molecular "building blocks" have been deformed. Ε3
The camera may be mounted on a tripod or fixed in a permanent loca tion. Price of this unit and t h e console is approximately $3550. Ε2

argues, writes letters t o the papers, and all finally vote, either directly or in directly. An attack upon the school problems in that way would not have brought forth "14 points," with no analysis of their relative importance, where subjects like chemistry or gram mar, that can be taught, are confused with "attitudes," such as "respect and appreciation for human values . . ." that can be caught by association with those who have them, but not taught. In place of the complacent statement that "the schools are doing the best job in their history in teaching these skills," it might have been possible t o arouse among the participants some of the true, but unperceived implications of the fourteenth point, "An awareness of our relr " nships to the world commu nity."
