A set of electric arc evaporators has been installed inside the gas dynamic trap experimental facility of the Budker Institute Novosibirsk. It is used for fast Ti-coating of the inner chamber surface. In this way the vacuum conditions could be substantially improved. Under the new conditions special experiments were carried out to measure the temporal and spatial variation of the neutral gas density during typical shots. The results of these measurements are presented and compared with those of numerical simulations by means of the Monte Carlo code TUBE.

Keywords: gas dynamic trap; vacuum conditions; Ti-coating; electric arc evaporation; neutral gas; Monte Carlo calculation
