Daniel Alpert

from Wikipedia, the free encyclopedia

Daniel Alpert (born April 10, 1917 in Hartford , Connecticut ; † November 4, 2015 in Eugene , Oregon ) was an American physicist who is best known today for the ionization vacuum meter he described , named after the inventor Robert T. Bayard and named after him Bayard-Alpert vacuum meter.

Life

Daniel Alpert received his Bachelor of Science degree from Trinity College, Hartford , in 1937 . From 1937 to 1941 he worked at Stanford University with William Webster Hansen in the field of microwaves; there he also learned from Sigurd Fergus Varian , who built the first klystron at that time . In 1942 he received his doctorate from Stanford University. From October 1941 he worked at the Westinghouse Research Laboratories in Pittsburgh , where he developed components for radar systems. In 1945 he also worked on the Manhattan Project , where he worked with Ernest Lawrence on the separation of the uranium isotopes. From 1957 he worked as a professor of physics at the University of Illinois . There he did pioneering work in the field of learning with the help of the computer, he was a co-founder of a corresponding research laboratory and contributed to the development of the computer system PLATO . 1987 Alpert retired, but he continued to work, e.g. B. as a consultant.

Services

Alpert is particularly known for his contribution to the development and description of the ionization vacuum gauge .

Honors

In 1957 Alpert received an honorary doctorate from Trinity College, and in 1965 a Guggenheim scholarship in physics. In 1980 he received the Gaede Langmuir Prize from the American Vacuum Society AVS for his contributions to the generation, measurement and application of ultra-high vacuum.
