The SFR set up a study center in the free zone in Lyon. The Personnel Department was instructed to facilitate the transfer of all Jewish employees who wish to move there. A small factory was also set up in Algiers. Controlled by the occupants as a Telefunken production center, SFR produced mainly for the German army. 65% of its turnover was devoted to German armaments from 1940 to 1944, reaching 86% in 1943. The number of employees was 2,600 in February 1940, dropped to 1,000 in August 1940 but then rose to more than 4,000 by 1943. Most of the output was equipment designed by Telefunken. Several capital increases were arranged, supported by BPPB. Pierre Grivet, a graduate of the École Normale Supérieure, was appointed to the Lavallois-Perret research laboratory during World War II and participated in a project to develop a 60kV oscilloscope, needed for television research. Grivet acquired expertise in electron optics, and obtained a government order for an electrostatic electron microscope during the period of German occupation. In the early 1950s Robert R. Warnecke was director of microwave research at the CSF in Paris. After World War II Radio-cinéma moved to Courbevoie, near to the other factories in Levallois. The project to develop the Spectro-Lecteur spectrum analysis device was launched at Radio-Cinema in 1947 in response to a request from the metallurgical company Pechiney. Early in the 1950s Radio-Cinema acquired the company of André Charlin, an engineer known for his expertise in talking movies, loudspeakers and stereophonics. In 1954 Radio-Cinema became the Compagnie des Applications Mécaniques et Electroniques au Cinéma et à l'Atomistique (CAMECA). The company retained its core business but diversified into precision engineering, making scientific instrumentation and aerospace radars. In 1955 CAMECA was structured with three departments, one to produce Radio-Cinema and Charlin film projectors, one undertaking mechanical production for other CSF subsidiaries, and the third working on the Spectro-Lecteur. CAMECA went on to develop ion and electron microprobes. In 1957 the CSF absorbed the SFR. In 1968 Thomson-Brandt and CSF were merged to form the large Thomson-CSF group. Thomson-CSF was nationalized in 1982 and privatized in 1997.
