Synthetic details of the polymers, UV-vis absorption, XRD patterns and typical output and transfer curves of OFET devices.

We experimentally study the characteristics of supersonically flowing helium plasma along a mirror and cusp magnetic field, including the flow direction along open field lines. The plasma is initially generated by arc discharge under atmospheric pressure, followed by a supersonic expansion into a weak uniform longitudinal magnetic channel in a rarefied gas wind tunnel as a plasma expansion chamber, and finally, expanded along the mirror or cusp magnetic field. Along the mirror type magnetic field, the plasma forms a high potential region around the plasma boundary and a low potential region around the axis of the plasma. For the cusp type, we observed a dark region, which is considered to be a shock wave.

We report effects of mirror and cusp magnetic fields on arc-jet plasma flow. For the weaker magnetic field, we experimentally found that ions move in more random directions and some of them even across the magnetic field. On the other hand, the direction of the ion flow in the downstream comes close to that of the magnetic lines of force due to Coulomb attractive force by electrons, which are fully magnetized under the present experimental conditions. Along the mirror type magnetic field, the plasma forms a high potential region around the radial boundary of the plasma and a low potential region around the axis of the plasma. For the cusp type, we observed a dark region near separatrix, which is considered as a shock wave.
