TY - JOUR AU - Robotti, Nadia AB - Among the most important detecting devices in the 1930s, cosmic-ray experimental physics figures the so-called counter controlled cloud chamber. This apparatus was jointly developed in 1932 by P M S Blackett, the cloud chamber expert at the Cavendish Laboratory in Cambridge and by G Occhialini, who mastered the counting coincidence technique following his work under the guidance of B Rossi in Florence. In this paper we address the original technical description of the apparatus and place its development within the historical and scientific framework of 1930s physics.
