ANALYTICAL CHEMISTRY
REPORT FOR ANALYSTS stitute of Nuclear . Study and the Radiation Laboratory work closely with their parent universities. The staffs generally hold university as well as laboratory appointments. Graduate students can then be em ployed part time in the nuclear field while they are studying for their de grees. The Hanford Engineering Works sponsors courses at the University of Washington, Washington State Uni versity, and Oregon State University. It also operates a large training school for its own employees. Some of these last named institutes are not National Laboratories, but many of their aims, financing, and type of personnel arc very similar to those of the National Laboratories. Argonne Program Typical. Most of Argonne's training programs are for those at the graduate and postdoctorate level. Many of the more formally organized courses are weighted on the engineering side, be cause one of the laboratory's main in terests is in reactor development. A summary of a report on training activities, prepared by Stuart McLain, shows the variety of educational pro grams at Argonne. In the category of Special Scien tific Loaned Employees are people from industry or the armed services who are sent to the laboratory for one or two years to become fully ac quainted with a section of the nuclear field by on-the-job training and work. Many of them already have some ex perience in the field. Resident Research Associate is the title applied to university staff people, postdoctorate appointees, National Re search Council appointees, and certain groups of aliens who study at Argonne. The university instructors generally fall,into two groups, those staying at Argonne for anywhere from six months to two years, and those com ing on summer appointments only. These personnel are generally given considerable freedom in carrying out their own research, and, of course, are welcome to participate in any of the intralaboratory seminar and educa tional programs. Summer Institutes comprise an other relatively new feature of the program. Last year an institute was sponsored in cooperation with the American Society of Electrical En gineers and the National Research Council and was attended by some 61 university instructors. The course work presented covers many aspects throughout the atomic energy field. This summer a similar institute was held at the Brookhavcn National Laboratory.
