CStatistical Information on Elementar~r-Particle Physics Research in the United States PHYSICISTS AND GRADUATE STUDENTS IN ELEMENTARY-PARTICLE PHYSICS Table C. 1 gives the number of Ph.D.-level physicists doing elemen- tary-particle physics research in the United States. The total increases to about 2400 when the number of graduate students doing doctoral research in elementary particles is added in. Figure C.l shows where the Ph.D.-level physicists work. Table C.2 gives the number of doctorates in elementary-particle physics granted per year in the United States. The number of elemen- tary-particle physics doctorates is compared in Figure C.2 with all physics doctorates and with all physical science doctorates. These personnel data come from the Report of the Technical Assessment Committee on University Programs, DOE Report DOE/ER-0182 (1983~. FUNDING FOR ELEMENTARY-PARTICLE PHYSICS RESEARCH Elementary-particle physics research is supported by the Depart- ment of Energy and by the National Science Foundation in the United States. Figure C.3 shows the total funding for elementary-particle physics in the United States since 1967. The funding is corrected for inflation and expressed in equivalent 1984 dollars. 209
