A magnetic sail (MagSail) is a unique interplanetary propulsion system. To propel a spacecraft in the direction leaving the Sun, the MagSail produces a large-scale magnetic field to block the hypersonic solar wind plasma flow. In order to simulate the interaction between the solar wind and the artificially deployed magnetic field produced around a MagSail spacecraft, a laboratory simulator was designed and constructed inside the space science chamber at ISAS/JAXA. As a solar wind simulator, a high-power magnetoplasmadynamic arcjet is operated in a quasi-steady mode of approximately 0.8 ms duration. It can generate a simulated solar wind that is a high-speed (above 20 km/s), high-density (10(exp 18) /cu m) hydrogen plasma plume of approximately 20 cm in diameter. A small coil (2 cm in diameter), which is to simulate a MagSail spacecraft and can obtain 1.9 T magnetic field strength at its center, was immersed inside the simulated solar wind. Using these devices, the formation of a magnetic cavity (approximately 8 cm in radius) was observed around the coil.
