Ady Hershcovitch

Ady Hershcovitch is a plasma physicist best known for his 1995 invention, the plasma window,[1] which was later patented. (United States Patent: 5578831:Hershcovitch).[2] In the plasma window, a plasma (which is an ionized gas confined by electric and magnetic fields) separates air from a vacuum by preventing the air from rushing into the vacuum. This scientific development can facilitate non-vacuum ion material modification, manufacturing of superalloys, and high-quality non-vacuum electron-beam welding.[3][4] The device has been compared to the force field in the Star Trek TV series.[5] He is well known for his work in plasma physics at Brookhaven National Laboratory.[6][7] He has over 80 publications[8] and 15 patents.[9]

Academic career

Hershcovitch earned his Masters in Nuclear Engineering in 1975 and his Sc.D. In Applied Plasma Physics in 1977 at the Massachusetts Institute of Technology.[10] In 1980, Hershcovitch continued his research at Brookhaven National Laboratory in Upton, NY.[11] Some of his most notable research involves development of plasma windows for transmission of synchrotron radiation and particle beams, in-situ coating techniques for Relativistic Heavy Ion Collider (RHIC) designed to reduce cold-bore resistivity and electron cloud formation, working on the Active Denial System (ADS) for radioactive waste transmutation and sub-critical nuclear reactors, development of electron guns with plasma cathodes, directing projects in Russia aimed at development of high charge state DC ion sources for MeV ion implanters and developing a non-vacuum electron beam and in-water techniques like welders and water purifiers.[12][13] He was an adjunct professor at Southern Methodist University in Dallas, Texas from 2006-2010 and is currently an adjunct professor at Stony Brook University in Stony Brook, NY.[14][15]

International collaboration

In Tomsk, Russia, Hershcovitch works as a consultant for Plasma Sources LTD.[16] He also works with the Skolkovo Foundation as a Nuclear Cluster Expert Panel Member to promote research that can result in commercial products.[17] Since 2010, Hershcovitch has also been a visiting scientist at the Riken Nishina Center in Wako, Japan.[18]

Awards and honors

In 1987, he received the I.R. 100 Award for the development of ion-sensitive probe and in 1996, after patenting the Plasma Window, Hershcovitch received the R&D 100 Award, both selected as one of the 100 most significant technological developments worldwide.[19] On October 1, 2007, he was elected to the American Physical Society Fellowship.[20]

Personal life

Hershcovitch is currently married to Kathy Hershcovitch and resides in Long Island, NY.[21]

Media

Hershcovitch’s plasma window was featured on the History Channel program "The Universe" pertaining to Weapons of the Future.[22] The Plasma Window is featured in book by Michio Kaku titled “Physics of the Impossible”.[23] New Scientist has listed the plasma window as one of the 10 impossibilities conquered by science.[24]
