A set of drift chambers built for the FRAMM-NA1 spectrometer

Abstract This paper describes the module of the drift chamber system used at CERN in a multiparticle magnetic spectrometer (FRAMM-NA1). Details are given about a new construction procedure which allows the quick and easy assembly of the chambers. Tests have been performed to check the construction accuracy, the detection efficiency and the final spatial resolutions, the results are reported. agger;
