Howard Wieman
Howard Henry Wieman (born in 1942) is an experimental nuclear physicist specializing in instrumentation and detectors for high-energy heavy ion physics.
Wieman received his bachelor's degree from Oregon State University in 1966 and his doctorate in 1975 from the University of Washington, studying with Isaac Halpern.[1] He was a post-doctoral fellow at the University of Colorado and then spent the bulk of his career as a Senior Scientist at the Lawrence Berkeley National Laboratory. At times, he also worked for and in collaboration with the Gesellschaft für Schwerionenforschung (GSI, Darmstadt). He retired from LBNL in 2011 but remains active in research.
At LBNL he was responsible for the design and installation of the Low Energy Beam Line at the Bevalac heavy ion accelerator and for the development of two generations of large Time Projection Chambers (TPCs). His first TPC was the EOS Time Projection Chamber at the Bevalac,[2] which he co-led with Hans-Georg Ritter. Wieman then led the design and construction of a large TPC for the STAR experiment at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. At the time of installation, the STAR TPC was the largest in the world[3]. He finished his career working with thin, high resolution, active pixel sensors. In particular, the Heavy Flavor Tracker (HFT) pixel detector for the STAR experiment was a ground-breaking device. It became operational in 2014 and was used to observe D mesons produced in heavy ion collisions.[4]
Wieman is a fellow of the American Physical Society, was awarded the LBNL J.M. Nitschke Technical Excellence Award in 1999[5], and received the APS Tom W. Bonner Prize for Nuclear Physics in 2015.[1]
