Professor David R. Winn

Senior Technology Advisor

Prof. David R. Winn has extensive experience in experimental nuclear and high energy physics, compact accelerator technologies, and wide-ranging experience in radiation detectors, electro-optics, scintillator development, thin film deposition, high speed data-acquisition R&D, data analysis and simulation software. In detector R&D work, Dr.Winn has developed: thin diamond film detectors; quartz fibers coated with thin films of BaF2; liquid core scintillating fibers; sub-ns decay liquid scintillators; high speed low energy (<10 MeV) electron accelerators; micro/nano-machined Photomultiplier tubes(PMT), Silicon micromachined MicroChannelPlates; and very large vacuum photocathode detectors. He has skills in thin film deposition, photolithographic techniques, MEMS, nanofabrication, electrochemical etching with extensive experience in the use & properties of high speed photodetectors, scintillators, low noise electronics, fiber optics, quantum optics, imaging devices, radiation damage, and very large scale projects.


 He has managed large projects funded by the DOE, and has obtained over $13 million in government funding since 1989. He has been a PI for DOE, NSF and NASA.


He has co-founded 2 high-tech companies as CTO, and obtained investment funding of $4m, and government funding of $8m. He was Assistant Professor of Physics at Harvard, and presently is Professor and (past and acting) Chair of Physics at Fairfield University. To date he has mentored 43 undergraduate students in research here or in Switzerland, and has supervised in part 7 PhD students.


He is the author or co-author of over 300 scientific and technical publications, 4 with over 500 citations, and one with over 4000 citations – considered renowned publications. He holds 8 patents, with provisionals filed.


Experiments in particle & fields, high energy and astroparticle physics include the Intensity, Energy and Cosmic Frontiers. Most recently he was one of the co-discoverers of the Higgs Boson at CERN – the so-called God Particle. Significant development work went towards SSC calorimetry, including the invention by his group at Fairfield University of the parallel Cerenkov fiber technique, tested at BNL 1992, then taken to CERN and adopted by the Large Hadron Collider Experiment CMS(joined 1994) after a technical shootout as the high raddam (>1 GRad) forward calorimeter (HF)- many of the unusual design features of HF were worked out originally by him & team at Fairfield. The current Forward Calorimeter HF quad- thin- window metal envelop high QE PMT Phase I Upgrade was proposed by him in a CMS White Paper (2009), tested with U.Iowa (2010-12) and installed 2014. The Cerenkov/dual readout Compensation Technique was invented by him c.1988 [“Compensating Hadron Calorimeters with Cerenkov Light”, D. R. Winn and W. Worstell, IEEE Trans. Nuc. Sci. Vol. NS-36, No.1, 334(1989)] and a novel new form of calorimetry, using Secondary Emission (arXiv:1308.8051). He also worked on muon colliders with Bob Palmer/BNL (1993-2003), and first suggested solenoid focusing/confining elements in the proposed muon ionization cooling system. He currently is working on CMS Phase II detector research to enable calorimeters to survive 3000 fB-1 at 5.5>?>1.5, applicable to Intensity & even Cosmic Frontiers.


His career so far has included hybrid bubble-spark chamber experiment for K, p inclusive reactions (E2B at Fermilab). Harvard Penn Wisconsin neutrino experiment at Fermilab(E1A/E310; ~1Coulomb of protons on target); the Harvard Purdue Wisconsin Proton Decay Experiment in Park City where limits on p->mu+x were measured, as well as upward-going atmospheric neutrino muons and muon bundles; Muon (g-2) - E821 at BNL/ ~2.8 sigma discrepancy from the present Standard Model calculations; and other nuclear and high energy detector R&D.
