James H. Christenson

from Wikipedia, the free encyclopedia

James H. Christenson (* 1937 ) is an American experimental particle physicist , best known for his involvement in the discovery of CP violation with James Cronin and Val Fitch (who received the Nobel Prize for it ) and René Turlay (1964).

Sometimes it is also incorrectly spelled Christensen. He is called Jim Christenson.

Christenson was a PhD student at Princeton University at the time of the CP violation detection experiment conducted at Brookhaven National Laboratory (PhD thesis 1964, mesons and the mass difference ). He later went to Fermilab , where he retired in the early 2000s. Among other things, he dealt with the development of calorimeters. Most recently, he was significantly involved in the upgrade of the D0 experiment. In 1995 he was involved in the discovery of the top quark as part of D0 . He was a professor.

In it he is named as one of the leaders of the upgrade for the 2nd run (started 2001) alongside Hugh Montgomery, Mike Tutts, Harry Weerts. Despite its age, the detector lasted until the end of the measurements in 2011.
