14. Research Groups

When the Second World War began the British demand for physicists exceeded the supply. In 1939 the Cavendish was producing 160 physicists a year, with 40 researchers and 20 assistants. In the years following the war these numbers increased tremendously, and by 1948 had reached a peak of 600 physicists a year, with 160 in research. The War also prompted the introduction of telephones and secretarial staff to the Cavendish.

With this many researchers working in the Cavendish the old system of supervision by a single Professor was impossible. A group system was introduced, with groups in nuclear physics, radio research, low temperature physics, crystallography, the study of metals, and mathematical physics. Individual research students would answer to the head of their group, and the heads would meet regularly to report their progress to each other.

The influx of students and researchers after the war meant that the Austin Wing, intended to meet needs for the next thirty years, was full within ten. Physics had become a subject that interested the public, and during the summer holiday the Laboratory received around 100 visitors a week. Its archives were put in order and used to construct the Cavendish Museum, now found at the new Cavendish Laboratory in Madingley Road.
