Personal Life

Cecil Powell was born on 5th December 1903 at Tonbridge, Kent, England. His father, Frank Powell, was a local gunsmith and practiced the family trade for years. Powell’s grandfather, George Bisacre, had connection and influences as he had established a private school in the town of Southborough.

Childhood & Early Life

He won a scholarship at the age of eleven in Judd School, Tonbridge. After gaining his elementary education from local school, this was a big step and the beginning. Powell later went on to win open scholarships to Sidney Sussex College, Cambridge.

Childhood & Early Life

After graduating with First Class Honors in Natural Science Tripos, Powell went on to work in the Cavendish Laboratory under C.T.R Wilson and Lord Rutherford in 1927. Here, he conducted a research on the condensation phenomena and earned a Ph.D. in Physics.

Childhood & Early Life

His professional career began in 1928 after he completed his Post Graduation. He started working as a research assistant to A.M. Tyndall in the H.H. Wills Physical Laboratory when he moved to the University of Bristol.

Career

He was also the director of a European expedition which made high-altitude balloon fights in Sardinia (1952) and in the Po Valley (1954, 1955, and 1957).

Career

Cecil Powell devoted a large part of his life to the development of techniques for measuring the mobility of positive ions, in order to establish the nature of ions in common gases.

He also worked on the construction of a Cockcroft generator to accelerate fast protons and deuterons. He employed them in conjunction with a Wilson Chamber to study the neutron-proton scattering.

Later on, he began developing methods which employed specialized photographic emulsions which would later be used to record the tracks of elementary particles. In the year 1938, Powell applied this technique to study cosmic radiation, and exposed photographic plates at high-altitude. He collaborated with Giuseppe Occhialini, H. Muirhead and young Brazilian physicist César Lattes for this work and the result was achieved in the year 1946, with the discovery of Pion (Pi-meson), the antipion (π−) in 1949 and the modes of decay of kaons (K-mesons).

He was also involved in the preparations of the pioneering Pugwash Conference on Science and World Affairs in the year 1955. He also chaired the meetings of the Pugwash Continuing Committee often filling in for Bertrand Russell. He was a part of the committee till 1968.
