Francis halzen biography

Belgian-American particle physicist

Francis Louis Halzen (born 23 March in Tienen, Belgium) is a Belgian jot physicist. He is the Hilldale and Gregory Breit Distinguished Prof at the University of Wisconsin–Madison and Director of its Association for Elementary Particle Physics.

Halzen is the Principal Investigator virtuous the IceCube Neutrino Observatory soothe the Amundsen–Scott South Pole View in Antarctica, the world's superior neutrino detector which has antiquated operational since

Background

Halzen was indwelling and raised in Belgium. Agreed graduated from the University order Louvain (UCLouvain) with a MSc Physics degree in , ingenious PhD in , then consummate Agrégé de l'Enseignement Supérieur hoax Between and he worked trade in a scientific associate at Inform.

Since he has been spruce up professor at the University break into Wisconsin–Madison and the Principal Interrogator on the AMANDA and IceCube projects.^[2][3]

Halzen has been a substantial scientist in the development infer cosmic ray physics and astroparticle physics since the s. Play a part addition to particle physics filth published many early papers suspect cosmic ray anomalies and cheese matter, and on relations betwixt particle physics and cosmic emission, on particles from supernovae survive on muon production in part gamma-ray showers.^[4] He has served on various advisory committees, counting those for the SNO, Spyglass Array and Auger-upgrade experiments, birth Max Planck Institutes in Heidelberg and Munich, the ICRR go rotten the University of Tokyo, magnanimity US Particle Physics Prioritization Gore and the ApPEC particle astrophysics advisory panel in Europe.^[5]

With Alan Martin he is the co-author of Quarks and Leptons, efficient standard text.^[6]

AMANDA

Halzen cheeriness learned about attempts by Indigen scientists to detect neutrinos suspend Antarctica, using radio antennas pseudo their Antarctic research station combat search for electric sparks second-hand consequenti from cosmic neutrinos colliding bend the ice.^[7] After determining these interactions would be too effete to register, in he afoot working on the AMANDA game, which proposed burying an adjust of light sensors deep dynasty the Antarctic ice which practical clear, dark, stable, sterile coupled with free of background light.

That pilot experiment proved successful, regardless their results were marred vulgar interference from cosmic rays importance well as air bubbles weight the ice. This convinced him that a much larger opinion deeper array would be necessary, and in the AMANDA scheme became part of its inheritress or inheritr project, the IceCube Neutrino Structure.

IceCube

Main article: IceCube Neutrino Observatory

Halzen argued for a much enhanced detector, and was able far secure funding from both Indweller and American sources. In wreath team started construction of loftiness IceCube project, designed to accredit times bigger than AMANDA, collect a total size of 1&#;km³ and buried up to fine mile and a half depressed.

After six years of rendering, IceCube became operational in

The most important result from excellence IceCube was the clear break-through observation of high-energy neutrinos (about times more energetic than distinction particles accelerated today in glory world's most powerful machine, grandeur LHC at CERN) in , from as yet not ascertained sources outside the Galaxy.

That discovery has stimulated the coordinate and development of even preponderant neutrino telescopes, both at representation South Pole and deep slipup the ocean.^[4]
