Evsei Rabinovich
Evsei Markovich Rabinovich, was a Russian physicist of Ukrainian origin who participated in the former Soviet program of nuclear weapons, and was one of the designers of the two-stage RDS-37 thermonuclear discharges and its successor, the RDS-220, the largest ever bomb.
Education
He studied engineering physics at the Moscow Engineering Physics Institute, and was honored with the Doctor of Sciences degree before joining the Soviet program of nuclear weapons in 1954.Soviet nuclear weapons programme
Rabinovich worked at KB-11, now known as the All-Russian Scientific Research Institute of Experimental Physics, where a significant group of physicists, mathematicians and chemists worked in secret; his work was under the direction of Yakov Zeldovich, a principal physicist who was directing research groups at KB-11 and the Institute of Chemical Physics.During the development of the RDS-220, Rabinovich became concerned that the device would not work and shared his worries with colleagues before raising them with his superiors. His concerns were taken so seriously that after discussion with the project design leads Viktor Adamsky, Vyacheslav Feodoritov and chief weapons designer Andrei Sakharov, all of whom provided counter-arguments, Sakharov altered the design of the bomb to reduce the margins of error in calculating the processes which had vexed Rabinovich.
