Research Achievement

After a few years of efforts we have established a leading position domestically in space science research, space instrument fabrication and test and calibration facilities, advanced space instrument development, execution of satellite missions and sounding rocket experiments, building of nano-satellite bus, space propulsion technology development, etc. We have also developed the only magnetized plasma experimental program in Taiwan by constructing a small magnetic mirror device and high temperature diagnostics systems. We have also conducted theoretical and simulation studies for applications in space and laboratory plasmas and fusion energy research.

We have recruited an outstanding research team with both internationally renown senior scientists and talented junior scientists. Our research capability is recognized in Asia only next to Japan in space science research and space instrument development and facilities. With the international recognition of space instrument development capability, we are invited to participate in Japan’s ERG satellite mission by contributing an electron instrument (LEPe) which measures electrons in 10 EV – 20 keV energy range. Below we briefly describe the accomplishments.

A. Advanced Space Science and Instrumentation Development:

We have established core expertise and capabilities in advanced space science research, satellite science instrument development, and execution of satellite and sounding rocket missions. ISAPS is the only integrated institute with capabilities in both space and plasma science and technology.

A.1 Space Instrument Development Facilities and Plasma Experimental Laboratory:

We have established Taiwan’s first state-of-the-art space instrument Fabrication, Test and Calibration (FT&C) facility with a 130 keV particle beam source in a 100K class clean room for advanced particle instrument development, fabrication, test and calibration. This facility is among the best in the world and there is only one similar facility in Japan. We have also constructed a Space Plasma Operation Chamber (with 2m in diameter and 3m in length) that is the second largest plasma chamber in Asia, and is only smaller than the space plasma chamber at ISAS, Japan, but with more advanced functions. SPOC will be used to test and calibrate low energy plasma and field instruments and for testing space propulsion technology such as plasma thrusters. To develop optical imagers for satellite mission we have establish a Space Optical Instrument Laboratory in a 100 K clean room. To study basic and innovative magnetized plasma physics relevant to space plasma science in the magnetosphere we have established a Magnetic Mirror Plasma Device which is 40 cm in diameter and 1.5m in length, and has the maximum magnetic field strength of 2 kG.

A.2 Space Instrument Development:

We have signed a contract with National Space Organization (NSPO) to conduct a sounding rocket experiment by developing the following instruments: Langmuir Probe that measures electron density and temperature; Ion Energy Analyzer that measures ion energy distribution and thus density and temperature; Neutral Particle Analyzer that measures neutral particle energy distribution, and Magnetoresistive Magnetometer that measures DC and low frequency magnetic field fluctuations. The se instruments have been completed and will be deployed in a sounding rocket experiment in 2013.

We also signed a contract with NSPO to develop six space-grade single-band optical imagers forthe FORMOSAT-6 satellite mission which was planned for launch in 2013-2014. We have manufactured the prototype of 4 single-band CMOS-based cameras and 4 single-band CCD-based cameras (762nm, 557.7nm and 630nm broadband and narrowband filters) and developed the science data processing unit.

We have an agreement with Japan’s ERG (Energization and Radiation in Geospace) satellite mission team to participate in the ERG mission by developing a top-hat electrostatic electron energy sensor, LEPe, which covers the electron energy range of 10eV–20keV. ERG satellite is now planned for launch in 2014-2015 to study the particle energuzation and loss processes in the Earth’s radiation belts. LEPe will be the first Taiwan made space particle instrument deployed in foreign satellite mission.

A.3 Space Science Research:

We have been working on critical space science research areas in the Living With a Star (LWS) program, and the Space Weather program, the magnetosphere-ionosphere coupling, and auroral substorm breakup arc structure and dynamics. The LWS research deals with solar storms which produce solar flares and coronal mass ejection (CME). To understand the dynamics and structure of large flares and CMEs we have established an impulsive magnetic reconnection model and performed observational data analysis of solar flares and CMEs. The Space Weather research deals with the effects of solar storms and solar winds, which cause geomagnetic storms and substorms in the geospace environment. Employing observation data from the satellites and ground-based instruments of the THEMIS mission and the ISUAL optical instruments aboard the FORMOSAT-2 satellite and, we have achieved high temporal and spatial resolution observation of substorm auroral breakup arc structure and dynamics from space, showing azimuthal mode number m ~ 200 in fine structure along the arc just prior to substorm onset. We have developed the world-leading kinetic ballooning mode theory to predict and explain the auroral substorm breakup arc observations. We have also worked on global distribution of electron density in the ionosphere and its evolution in support of the GPS radio occultation experiment by the FORMOSAT-3/COSMIC satellites.

A.4 International Collaborations:

We have established international collaborations with several world premier space research groups such as the SSL/UCB in USA; ISAS/JAXA and Tokyo University and Kyoto Universityand Nagoya University in Japan; Swedish Institute of Space Physics in Sweden; Kyung HeeUniversity in Korea; and GeoForschungsZentrum Potsdam in Germany. In particular, we have a collaboration agreement with Prof. Masafumi Hirahara of University of Tokyo and Dr. Kazushi Asamura of Institute of Space and Aeronautical Science (ISAS), Japan, to develop the LEPe instrument for deployment in Japan’s ERG satellite mission. We have recently reached a collaboration agreement with Prof. Robert Lin of SSL/UCB to develop the STEIN sensor, a state-of-the-art palm-sized sensor with high resolution to measure simultaneously 2 – 300 keV electrons, 4 – 300 keV protons and energetic neutrals, and 2 – 20 keV X-rays, for Taiwan’s future satellite missions. In 2009 we were invited by Prof. Masaki Fujimoto of ISAS/JAXA to participate in the SCOPE (cross-Scale COupling in the Plasma universE) mission by developing particle instruments and/or providing daughter satellites. In the SCOPE mission 5 satellites (one mother ship and 4 daughter ships) are planned for launch in ~2018-2019 to study fundamental plasma physics of Plasma Universe. We will continue to negotiate with ISAS/JAXA on the participation in the SCOPE mission.

B. Magnetic confinement fusion plasma theory and simulation Study

The basis of fusion study is the magnetic confinement fusion plasma science. So far the capability in fusion plasma experiments and diagnostics development in Taiwan is well behind other major developed and developing countries. In Taiwan only ISAPS has built a magnetic mirror device to perform experimental study of magnetized plasmas and developed magnetic confinement plasma theory and simulation for studying fusion science.

In the present stage we are studying drift waves and turbulence and their effects on plasma transport, electromagnetically induced transparency of EM waves. In the future, we will study the experiments of the propagation of Alfvén waves and electromagnetic ion cyclotron along highly nonuniform magnetic fields.

In fusion plasma theory, some faculty members are considered to be world-class experts. For example, Prof. C.Z. Cheng is an expert in Alfvén Eigenmodes and alpha particle physics of in toroidal confinement fusion plasma devices. He is responsible for the discovery of the Totoidicity-induced Alfven Eigenmodes (TAEs) and other types of Alfven eigenmodes, and predicted that TAEs can be destabilized by energetic particles and can cause serious loss of energetic particles. He also developed the NOVA-K family of codes, which are widely used in the fusion research community. Prof. K.C. Shaing is an expert of plasma neoclassical transport theory recognized internationally.

B-1 Magnetic mirror device and facilities of building

We have already constructed a magnetic mirror device to perform basic magnetized plasma physics experiements relevant to space and fusion plasmas. The magnetic mirror device (40 cmin diameter, 1.5 m in length) is equipped with 5 magnetic coils with maximum magnetic field of 2 kG, and a 30 kW, 2.45GHz magnetron for electron heating. The fusion relevant science includes Alfevn waves, drift waves (such as ion temperature gradient drift waves, electron temperature gradient drift waves, trapped electron instability, etc.), plasma turbulence and nonlinear excitation of convective cells and zonal flows. We have also developed advanced plasma diagnostics systems, such as microwave interferometry and reflectometry, for measuring high temperature plasma density and fluctuations.

We will continue to collaborate with Prof. Yasushi Ono of Tokyo University on laboratory plasma experiments and personnel exchange. We will also collaborate with Prof. Atsushi Mase of Kyushu University on development of advanced microwave diagnostics systems. We are also in discussion with Prof. Hyung Park of POSTECH in Korea participate in the KSATR tokamak experiment.

B-2 Plasma Fusion Theory and Simulation Study

ISAPS has world-class scientists with expertise in Plasma Fusion Theory and Simulation Study, including alpha particle physics in toroidal confinement fusion plasma devices, and alpha particle transport due to Toroidicity-induced Alfvén Eigenmode (TAE). In addition, we are developing state-of-the-art kinetic-fluid simulation codes by adopting gyrokinetic kinetic formulation and fluid models to study nonlinear wave-particle interaction in toroidal fusion plasma devices. We are also training students and postdocs to develop global equilibrium and stability codes by including plasma flows perpendicular and parallel to the external confinement magnetic field and by including non-MHD physics. We have also developed the theory of toroidal plasma viscosity in tokamak. We will continue to study these research areas, and train young scientists and students to conduct fusion study and international collaboration.

B-3 Synergetic approach to computational and theoretical plasma physics

Examples of research focus areas are

(a) Basic plasma physics: Plasma wave-particle interaction and kinetic instabilities, nonlinear waves dynamics (Langmuir solitons and Alfven solitons), and Hamiltonian chaos.

(b) Plasma processing: Heating mechanism of capacitively coupled plasmas, basic process of nano-scale plasma-material surface interaction.

(c) Magnetically confined fusion plasmas: magnetic reconnection events in tokamaks, alpha particle induced Alfvenic instabilities, and particle/heat transport in diverted tokamak plasmas.
