Biographical Sketch

George Ginther was born in Philadelphia, and raised in the southeastern corner of Pennsylvania.  He received his B.S. in Physics from Carnegie-Mellon University in Pittsburgh in May of 1977.  He received his M.S. in Physics from Carnegie-Mellon University in May of 1979, and moved to Fermilab in Batavia Illinois to pursue research interests.  Under the direction of Professor Richard M. Edelstein, he received his Ph.D. in Experimental High Energy Physics from Carnegie-Mellon University in May of 1985.  In the fall of 1985, he joined the University of Rochester staff as a Research Associate working with Professors Ferbel, Lobkowicz, and Slattery and based at Fermilab.  In 1988, he was promoted to Senior Research Associate.  In 2003, he was also appointed Senior Laboratory Engineer and promoted to Senior Scientist.

George Ginther has served as the Physicist-in-Charge for Fermilab fixed target experiment E706, and the GEM test beam program at Fermilab. He served on the Executive Committee of the Fermilab Users' Organization from 1991 through 1993. He also served as co-manager of the silicon microstrip tracking detector upgrade for DZero Run IIb. Other leadership positions include serving as coordinator of the Visible Light Photon Counter (VLPC) Cassette Production, Installation and Maintenance- Dzero Collaboration Fermilab (1997-now);  Project Manager - CMS Test Beam Motion Table at CERN (1998-2000);  Coordinator of DZero Central Fiber Tracker and Preshower Detectors Commissioning and Operations-Dzero Collaboration Fermilab (2001-2003); Co-Manager, DZero Run IIb Silicon Detector Upgrade Project- Fermilab, (2003), and DZero Deputy Technical Integration Coordinator - Fermilab (2004-now)


George Ginther's research interests are in the area of Experimental High Energy Physics.  His Ph.D. research was based upon the data acquired in Fermilab fixed-target experiment E515, which was a prompt muon triggered experiment using a two arm spectrometer.  This experiment provided him an opportunity to learn about a charged particle spectrometer based upon multi-wire proportional chambers and a large dipole magnet.  The focus of the experiment was on studies of the hadronic production of charm particles. 

Since joining the University of Rochester, a significant fraction of George’s effort have been devoted to Fermilab fixed-target experiment E706, which was a comprehensive study of hard scattering events yielding large transverse momentum direct photons and neutral mesons.  This experiment selected events that deposited significant electromagnetic energy in the lead and liquid argon electromagnetic calorimeter that was built specifically for this experiment.  The measured yields of high transverse momentum particles are substantially larger than anticipated from calculations based upon perturbative Quantum ChromoDynamics, highlighting the need for refinements in these QCD calculations.  This data also facilitated studies of the production of charm particles with large transverse momentum.  The spectrometer used to acquire the E706 data samples simultaneously recorded data selected via a high mass dimuon trigger for Fermilab experiment E672.  Studies of this dimuon triggered data provided insights into the production of several hidden charm states as well as bottom particles.

Along with Professors Demina, Ferbel, and Slattery, and Senior Scientist Zielinski, George Ginther is currently collaborating on the DZero experiment at the Fermilab Tevatron.  This experiment triggers on selected collisions of protons and anti-protons at the highest energies currently generated by a man-made source.  Studies of these hard collisions at the energy frontier yield insights into the fundamental forces and underlying symmetries of nature.  Upon joining the DZero collaboration in 1997, George became involved in the prototyping, production, and installation of the Visible Light Photon Counter cassettes used in readout of the scintillating fiber tracker designed and built specifically for DZero Run II.  He contributed to the commissioning and coordinated the operation of the fiber tracker and preshower detectors for more than a year, and then focused on preparations to upgrade the silicon microstrip tracking detector for DZero Run IIb.  Unfortunately, for reasons entirely unrelated to the Run IIb upgrade project, the Fermilab Director elected to terminate the approved project to upgrade the entire silicon detector.  After contributing to the preparation of the proposal for the new Layer 0 silicon detector, George has been asked to serve as Deputy Technical Integration Coordinator for DZero.

George Ginther has also been involved in preparations to continue explorations at the energy frontier.  During 1993, he participated in planning for a Fermilab based test beam program for the GEM experiment at the Superconducting Super Collider. From 1997 through 1999, George was responsible for coordinating the fabrication, testing, shipping, and commissioning of a test beam motion table specifically designed to facilitate testing of the hadron calorimeter modules at CERN for the CERN Large Hadron Collider experiment CMS.
