Wieman received his bachelor's degree from
Oregon State University in 1966 and his doctorate in 1975 from the
University of Washington. His doctoral advisor was Isaac Halpern. 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, which he co-led with Hans-Georg Ritter. Wieman then led the design and construction of a larger TPC for the
STAR detector at the
Relativistic Heavy Ion Collider (RHIC) at
Brookhaven National Laboratory. 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. Wieman is a
Fellow of the
American Physical Society, was awarded the LBNL J.M. Nitschke Technical Excellence Award in 1999, and received the APS
Tom W. Bonner Prize for Nuclear Physics in 2015. == References ==
