題　目：Laboratory Plasma Experiment and Space Instrument Development at PSSC/NCKU

要　旨：

I will introduce the laboratory plasma experiment activity and space instrument development effort at the Plasma and Space Science Center. To perform laboratory plasma experiments we have constructed a magnetic mirror device (MPX) with 40cm in diameter and 1.2 m in length and the maximum obtained magnetic field is 1.5 kG. The main heating source is a 30 kW magnetron with CW operation at 2.45 GHz. We have developed plasma diagnostics such as Langmuir probes, magnetic pickup coils, microwave interferometry and reflectometry, a spectroscopic The MPX has been used for student thesis research. I’ll also discuss the plan to study basic plasma physics relevant to fusion and space physics. Our other major effort is in the development of instruments for satellite and sounding rocket. We have also constructed instrument fabrication and calibration facilities which consist of (1) a 130 keV ion beam line and a plasma chamber in a 100K clean room, which will be used to develop energetic particle instruments, and (2) a large space plasma chamber with 2m in diameter and 3m in length, which can produce ionospheric plasmas and is used to test and calibrate low energy plasma instrument and electric and magnetic field instruments for satellite and sounding rocket missions. I’ll also discuss our plan on satellite missions and sounding rocket experiments
