Description
In the PANDA experiment, identification of charged particles in momentum region below about 1 GeV/c will be based on the measurement of energy losses in the central straw tube tracker. In order to make a choice between the charge integration and the time-over-threshold (TOT) techniques for the energy loss measurement, we performed tests of a prototype straw detector read out with a new front-end ASIC equipped with both analog and digital output. A very good performance of the TOT in a wide range of energy losses was observed. Results of tests agree with GARFIELD simulations of the straw tube response convoluted with transfer function for the front-end electronics. In the present contribution, the prototype module containing pressure stabilized straw tubes and the architecture of the front-end ASIC will be described and the results of the TOT measurements and simulations will be presented.
