volt betatron to produce rrcm: ray eff< s iSTATI N ory and op n ent ly n w door3 to sci' ntiJ r ir is un ] truetion on the Urbana-Champ -n camj. s. It wi t n >peration "me time in 19^9- Tho betatron is a machJ to elri el» ' by use of a magnetic fi^ld. The el :trons can eltrv • be • d directly or made to produce high-energy x-rays. The bet £ it nar from scientific use of the Greek symbol "beta" tc Lndlc high-speed electrons and the Greek suffix "-tron" r mlng "a der for." * Prof. Donald W. Kerst invented the betatron at the Univer. . where his first instrument went into operation July 15, 1940. • Its output was 2.3-million (2,300,000) volts. Betatrons of 22- and 75D llion volts also have been built at the University and others el Bere3 with the 22-million volt size being commercially produced. The V tatron is useful for industry as a powerful source of x-rays of 20to 30-million volts energy; to medicine as a source of x-rays or of free electrons at 20- to 35-million volts for use against cancer; to science as a source of x-rays or free electrons, with precision controi of their energies, to study the nucleus of the atom, and at more than 250-million volts energy to produce cosmic ray phenomena. A 22million volt betatron for cancer research will be in operation at the University's College of Medicine in Chicago early in 19^9The Illinl Union Building at Urhana-Champaign is a UNION BUILDING3 ''front door" to the campus and "community center" for students, faculty, alumni, and visitors. The $1,500,000 building was erected and furnished without cost to the state treasury. It has been described as "a distinguished social center for campus life, to develop a democratic student spirit and informal friendships, and to serve as an inspiration for better living." It includes lounges, food services, meeting rooms, game rooms, bowling alleys, browsing library, ticket sales windows, information window, and other services. Building manager is Vernon L. Kretschmer. The Chicago m i n i Union at 715 S. Wood St., serves the same purposes for students on the professional campus, while student centers are provided in the Undergraduate Divisions in Chicago (Navy Pier), and at Galesburg. Occupying the 20th floor of the Hotel LaSalle, CHICAGO ILLINI CENTER this provides general headquarters for the University in Chicago. Here are branch offices of the Alumni association, Division of University Extension, General Placement Bureau, and Division of Social Welfare Administration, as well as general meeting rooms, lounges for alumni, and facilities for University committees and functions. Phone is RAndolph, 6-7750. In charge is Harold S Dawson. The General Placement Bureau, with offices both in UrbanaPLACEMENT lampaign and Chicago, serves graduates and alumni. Its principal task is making contact with industry in all parts of Illinois and maintaing a file fo people available. It cooperates with placement work carried on by the various colleges and schools. It also assists graduates with vocational counselling. Director is Har Ld S. Dawson. University of Illinois colors are orange and blue. COLORS AND NICKNAME T Uni 3ity's symbol is the Indian. Its nick• me is Illinl, an Indian word Latinized in the University's early days with the following forms: male singular, Illinl; female singular, Illlna; r. r plural, Illlni; female plural, Illinae; collective plural Illinl; ge ., Illinl. It is pronounced "Ill-eye-nye."
