An electrostatic tandem-accelerator with 2.5 MeV 10 mA proton beam is under development at BINP. One of the accelerator important parts is a target that converts the half energy accelerated negative hydrogen ions into the proton beam. To reduce argon flux from the target to accelerator gaps a gas recirculation by turbomolecular pump installed in high voltage electrode is provided. To study the argon recirculation and the plasma production in the stripping cell an experimental test stand is prepared. Results of experimental modeling of differential pumping with different length of tubes for ion beam pass are presented. Ionization of the target by 500 eV electrons is studied by injecting a corresponding electron beam.
