Title: Famous People in Canadian Nuclear History


1
Famous People in Canadian Nuclear History
2
Dr. Bertram Brockhouse
(19182003)
  • July 1950 Joined the Atomic Energy Project of
    the National Research Council (later to become
    AECL)
  • Studied the scattering of slow neutrons at NRX
  • 1952 Developed a triple axis machine he called
    a large aperture double spectrometer to measure
    normal modes in a crystal

3
Dr. Bertram Brockhouse
(19182003)
  • 1962 Became Professor of Physics at McMaster
    University until his retirement in 1984
  • 1994 Shared the Nobel Prize in Physics for his
    work at NRX in the 1950s in the field of neutron
    scattering for condensed matter research

4
Dr. Harold Johns
(19151998)
  • 19391945 Served as Professor of Physics at the
    University of Alberta
  • 1945 Moved to the University of Saskatchewan
    where he shared his time between starting a
    medical physics group and the new Saskatchewan
    Cancer Commission in Regina

5
Dr. Harold Johns
(19151998)
  • 1951 Revolutionized cancer treatment with the
    development of the Cobalt Bomb, the cobalt
    cancer therapy unit
  • 1953 First published The Physics of Radiology,
    the first of four editions (last published in
    1983), the premier text in its field
  • 1956 Became head of the Physics Division at the
    Ontario Cancer Institute in Toronto

6
Dr. George Laurence
(19051987)
  • 1930 Joined the staff of the National Research
    Council of Canada (NRCC)
  • Helped improve radiation dosage measurements in
    the treatment of cancer
  • Helped develop radiation safety regulations for
    North America
  • 1940 Conducted pioneering work on nuclear chain
    reactions

7
Dr. George Laurence
(19051987)
  • 1961 Became President of the Atomic Energy
    Control Board and helped establish the Canadian
    reactor safety protocol
  • 1966 Received Medal for Achievement in Physics
    from the Canadian Association of Physicists
  • 1975 Received the W.B. Lewis Medal from the CNA
  • 1988 Awarded (posthumously) a special plaque
    from the American Nuclear Society

8
Dr. George Laurence
(19051987)
  • Was the first person in the world to induce
    fission by neutrons in large quantity of uranium
    surrounded by carbon
  • 1945 Moved to Chalk River working on reactor
    designs for ZEEP, NRX and NRU
  • 1950 Insisted on non-breeder power plant design
    for Canadian nuclear power. Led to the
    development of the natural uranium, heavy water
    reactor.

9
Dr. Wilfred Lewis
(19081987)
  • 193439 Served as research fellow with J.D.
    Cockroft on nuclear disintegration of particles
    accelerated by high voltages and then operating
    the Cambridge Cyclotron
  • 1939 Joined the Air Ministrys
    Telecommunications Research Establishment in
    Britain for the duration of World War II

10
Dr. Wilfred Lewis
(19081987)
  • 1946 Became director of the National Research
    Council of Canadas Atomic Energy Division (now
    AECL) at Chalk River where he oversaw the
    building of the NRX and NRU
  • Considered by many to be the father of the CANDU
    as he was involved in all major planning and
    decision making
  • 1982 Awarded the Fermi award for outstanding
    lifetime contributions to energy science research

11
Sir Ernest Rutherford
(18711937)
  • Although born in New Zealand, Rutherford had a
    significant impact in Canada with his work on the
    atom
  • 1898 Filled the position of Chair of Physics at
    McGill University in Montreal
  • 1907 Filled the position of Chair of Physics at
    the University of Manchester in England
  • 1908 Won the Nobel Prize in Chemistry for
    demonstrating that radioactivity was the
    spontaneous decay of atoms

12
Sir Ernest Rutherford
(18711937)
  • 1911 Established the nuclear theory of the atom
  • 1919 Announced he was the worlds first
    alchemist having successfully changed nitrogen
    into hydrogen and oxygen by alpha particle
    bombardment
  • Later that year he became the Cavendish Professor
    of Physics at Cambridge University
