Ady Hershcovitch
Ady Hershcovitch is a plasma physicist best known for his 1995 invention, the plasma window,{{cite web|title=Plasma Window| date=29 January 2016 |url=https://www.youtube.com/watch?v=UqWiKhLZLXo|publisher=WikiAudio|accessdate=25 September 2017}} which was later patented. (United States Patent: 5578831:Hershcovitch).{{cite journal|last=Hershcovitch|first=Ady|title=Method and apparatus for charged particle propagation|journal=United States Patent Office}} 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.{{cite web|title=Plasma Window Technology for Propagating Particle Beams and Radiation from Vacuum to Atmosphere|date=May 1998 |url=http://www.techbriefs.com/component/content/article/ntb/tech-briefs/electronics-and-computers/1834|publisher=Tech Briefs|accessdate=14 May 2017}}{{cite news|title=Acceleron Electron Beam, LLC, Wins Grant from the U.S. Department of Energy to Commercialize New Welding Technique Developed at Brookhaven Lab|work=BNL News Release|agency=Brookhaven National Laboratory.}} The device has been compared to the force field in the Star Trek TV series.{{cite news|title=Hot Mettle|url=https://www.newscientist.com/article/mg17823904-800-hot-mettle/|accessdate=14 May 2017|issue=New Scientist}} He is well known for his work in plasma physics at Brookhaven National Laboratory.{{cite web|last=Kren|first=Lawrence|title=New "window" of opportunity for e-beam welding|url=http://www.machinedesign.com/fasteners/new-window-opportunity-e-beam-welding|website=Machine Design|accessdate=24 September 2017|date=2004-07-08}}{{Cite book|title=Physics of the Impossible|last=Kaku|first=Michio|publisher=First Anchor Books|year=2008|isbn=978-0307278821|location=First Anchor Books|pages=[https://archive.org/details/physicsofimpossi00mich/page/10 10–11]|url=https://archive.org/details/physicsofimpossi00mich/page/10}} He has over 80 publications{{citation needed|date=April 2023}} and 15 patents.{{cite web|title=United States Patent Office|url=http://patft.uspto.gov./netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=0&f=S&l=50&TERM1=Ady&FIELD1=&co1=AND&TERM2=Hershcovitch&FIELD2=&d=PTXT|publisher=US Patent Office|accessdate=14 May 2017}}
Academic career
Hershcovitch earned his master's in nuclear engineering in 1975 and his Sc.D. in applied plasma physics in 1977 at the Massachusetts Institute of Technology.{{cite web|title=MIT Alumni Directory|url=https://alum.mit.edu/user/directory/Search.dyn?R=PxhT4bj96E9pIIavGLEl6A%3D%3D}}{{Dead link|date=September 2019 |bot=InternetArchiveBot |fix-attempted=yes }} In 1980, Hershcovitch continued his research at Brookhaven National Laboratory in Upton, NY.{{cite book|title=Directory and Survey of Particle Physicists|date=Jan 1, 1999|publisher=Diane Publishing|page=134|url=https://books.google.com/books?id=OauCs3O1vmAC&dq=brookhaven+national+lab+hershcovitch&pg=PA134|accessdate=14 May 2017|isbn=9780788175817}} 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.{{cite web|title=Plasma Physics R&D for Some non- Fusion Physics & Industrial Applications|url=http://apam.columbia.edu/files/seasdepts/applied-physics-and-applied-math/pdf-files/AHershcovitch.pdf}}{{cite journal|author1=A.
