A new compact cascaded arc device for plasma-wall interaction study is developed at the Institute of Plasma Physics, Chinese Academy of Sciences. A magnetic field up to 0.8 T is achieved to confine plasmas in a 1.2 m long and 0.1 m diameter vacuum chamber. Gas fluid type analysis in this compact vacuum system was done under high particle flux condition. The gas pressure obtained by calculation was consistent with the measurement result. Continuous argon plasma discharge with ion flux of ∼0.5×10 24 m −2 s −1 is successfully sustained for more than 1 h. The effects of magnetic field configuration, gas flow rate, and discharge arc current on the ion flux to target were studied in detail.

The main experimental works, where dipole polarizabilities of charged pions have been determined, are considered. Possible reasons for the differences between the experimental data are discussed. In particular, it is shown that the account of the σ-meson gives a significant correction to the value of the polarizability obtained in the latest experiment of the COMPASS collaboration. We present also new fit results for the (γγ → ππ) reaction.
