Dear Dr. Friedman: 

CHELSEA 3-1000 

July 9, 1954 

In reference to your conversation with Mr. A. w. 

Horton, Jr. of Bell Telephone Laboratories, we are referring the qualifications resume of Mr. Ronald Lee Wigington, a Member 

of our Technical Staff, who was inducted into the Armed Services 

on July 8, 1954. 

. As the enclosed summary indicates, Mr. Wigington was 

graduated from the University of Kansas in June, 1953, having been awarded the degree of Bachelor of Science in Engineering Physics. He was employed by these Laboratories on June 15, 1953 

and was assigned to electron tube analysis and development in 

our Transmission Dev~lopment Department. I understand from 

Mr. Wigington•s department that they have a very high opinion of his technical abilities. 

We have asked Mr. Wigington to inform us of the completion of his basic training in addition to his military address and serial number. Upon your request we 'Will forward 

this information to you. 

I understand that Mr. Horton also recommended another 

Member of our- Technical Staff, Dr. Harold S. Shapiro, who reported for induction on May 7, 1954. However, Dr. Shapiro has been 

reclassified 4-F and has since resumed his work with the Laboratories. 

If we can be of a:rJY' further assistance in this matter, 

please do not hesitate to call on us.

College Education - Undergraduate 

Graduated June 1953 from the University of Kansas, School of 

Engineering and Architecture. 

Degree - B.S. in Engineering Physics. 

Description or course: 

( 

The Engineering Physics curriculum includes the basic physics course or a liberal arts physics graduate with 

fundamentals or electrical engineering and other basic engineering co'Urses in place of the liberal arts student's nontechnical courses, including also a strong emphasis on mathematics. 

Graduate Credit 

University of Kansas (during spring semester 1953, senior year) Six hours• credit ing-aduate mathemat~cs - Introduction to 

Theo?')" of Functions and Introduction to Modern Algebra. 

Special Pro3ect Work in College 

During the senior year in a course called Special Problems, Mr. Wigington worked on the design and building of 

an automatic recording ionization chamber to be used as a 

safety device in the control room of the school's Van de Graaf 

generator. It was tobeused to record how much radiation the 

operators of the generator were exposed to. 

This project included the design, building, and testing of an ionization chamber to be used as a detector, the design of a special preamplifier housing and ionization chamber 

mount, the selection of a suitable DC amplifier and the adapta- tion or an old mechanical recordil)g Wheatstone bridge for measuring current. Mr. Wigington worked on the project alon.e, was 

able in the time available to complete all or it except the final 

building or the DC amplifier and the testing and calibration of 

the complete system.

Technical Employment 

• Phillips Petroleum Co., Bartlesville, Oklahoma. 

Summer 1951 (June l to August 15) 

Worked as a laboratory assistant in a chemical laboratory, Research and Development department, Division of Rubber 

and Chemicals. The work consisted essentially or preparation from the latex Of batches Of different types or synthetic rubber for use in an exploratory development plastics project and 

in operation of an experimental type ot apparatus used in sepa- rating catalyst from reactants in h7drocarbon solution. This 

included experimentation in methods of operating the apparatus and assisting in evaluating it for efficiency of catalyst removal. Other routine jobs in the project were also performed. 

Summer 1952 (June 1 to August 31), Phillips Petroleum Co. 

Was employed in the Physical Chemistry research group in the Hydrocarbon Conversion Division (R. and D. Dept.); designing and operating an automatic gas collection~y..ste:111used 

in evaluating catalysts for hydrocarbon conversion. Radioactive tracer techniques were used. 

Bell Telephone Laboratories, Inc. (6-16-53 to induction) 

1) June 15 to September 1. 

Performed some theoretical temperature studies on the 

grids of the M 1805 millimeter klystron. A severe grid burnout problem arose in the construction of this tube 

due to small size of the tube components and the high electron beam power densities encountered •. More specifi- cally, the method by which the grid elements are cooled 

(i.e., conduct.ion or radiation) and comparison of several 

grid structures for favorable thermal characteristics 

were studied.

2) September l to January 15. 

Second assignment was assisting in the building of an 

experimental interstage network in the 100 - 500 Mc 

range. The w~k involved measurements on a scaled up (in size, scaled do'WD. in frequency) model of the interstage to get an empirical feel for the criticallit7 

ot precision in component values, and construction and 

measlirement of components for the 100 - 500 Mc range. 

3) January 15 to date. 

Principal problem was setting up and operating a waveguide system in the millimeter wave range (midband is 

55.5 kmc) to measure the Q of cavities by the reflected 

power method. Included in this work was showing the 

practicality or using titanium deposited glass vanes 

for attenuator cards in precision calibrated attenuators for the millimeter wave range. 

Some Q measuring studies were set up for exploring the 

effect of surface treatment of hobbed millimeter wave 

cavities to check some results obtained by the British 

and to explore possibilities for improving the Q of the 

cavity or the M 1805 klystron. These studies are in 

progress now.
