Abstract
An array of 2424 2.6- m-long, 15-mm-diameter mylar straw tubes, arranged in two axial and four stereo layers, has been assembled at National Laboratories of Frascati of INFN for the FINUDA experiment. The array covers a cylindrical tracking surface of 18 m(2) and provides coordinate measurement in the drift direction and along the wire with a resolution of the order of 100 and 300 mum, respectively. The array has finished the commissioning phase and tests with cosmic rays are underway. The status straw tubes array and a very preliminary result from cosmic rays test are summarized in this work.
