一、 研究、教學、科技研發與管理工作全程經過概述。（由受聘人填寫）
Please summarize the entire research, teaching, or science and technology R&D and management work process (To be completed by the employee)
1. Development of a calibration facility for space plasma instruments
One of the missions of Plasma and Space Science Center (PSSC) is to develop our own satellite/rocket borne instruments for space plasma observation to contribute to advance space science in Taiwan and participate in international science community.
It has become important to have space plasma analyzers that can measure 3-dimensinal velocity distributions with wide energy range and fine time and space resolution for comprehensive understanding of space environment surrounding the Earth. A reliable calibration facility capable of simulating variety of space plasma flows is necessary to develop such analyzers.
A new calibration system for space plasma instruments that uses ion beam of energy range of 1 keV to 130 keV is being developed in a clean room of our space instrument laboratory.
The system consists of an ion source, an ExB mass spectrometer, a beam expander, a beam accelerator, a drift tube and a 3-axis turntable in the main chamber. Neutral gas such as N2, O2, He, and H2 is introduced to the ion source and ionized by an electron gun, then accelerated to energy of several keV/charge and move to the mass spectrometer. The mass spectrometer has a 90 degree crossed electric and magnetic field to select ion species of desired mass. Ion beam is expanded by means of oscillating electric field and electric field lens produced by a set of cylindrical electrodes.
Ions are then accelerated to up to 130 keV by a potential drop in the accelerator tube. The drift tube has a 2-dimentional-beam profile monitor. In the main chamber the 3-axis turntable is set up to house particle instruments for test and calibration.
– The ion source, the ExB mass spectrometer, the beam expander and the acceleration tube are designed, manufactured, assembled on the insulation deck and connected to the drift tube and the main chamber.
– Pressure of the ion source, the drift tube and the main chamber reach order of 10-8 Torr.
– High voltage power supplies to control the ion beam property and their remote control system have been developed and set up on the insulated deck.
– Neutral gas introduction system has been installed.
– Ion beams of 3 to 13 keV have been produced and ExB mass selection is confirmed by introducing N2 and Ar gas. It also detected water vapor remained in the chamber.
– Ion beam profile has been measured using an MCP with single anode and the 3-axis turntable.
– Electrostatic lens in the beam expander has been used to make focused beam as narrow as 5 mm in diameter.
– Purchased a100 mm x 15 mm rectangle MCP with a position sensitive resistive anode and a VME charge to distal converter for 2-dimensional beam profile measurement. Data acquisition software is under development.
– Designed electric field shield panels to install on the high voltage deck, which has been manufactured and delivered.
– Installed safety fence around the high voltage deck.
2. Development of a neutral particle analyzer for sounding rocket experiment.
Neutral Particle Analyzer (NPA) is being developed to measure energy distribution function of neutral atmosphere from SR10 sounding rocket that will be launched in 2013. Atmospheric neutral particles enter into the instrument as the rocket proceeds. Then particles are ionized by an electron beam and accelerated by a uniform electric field perpendicular to the incident velocity towards the detector plane. Only the particles with an incident energy determined by the
acceleration electric field can reach one of the two detectors through a slit in the detector plane.
By sweeping the acceleration electric field strength, full energy spectrum is obtained.
– Feasibility evaluation such as count rates and energy resolution estimation has been done.
– Parameters such as the size of the instrument, positions of the detectors, acceleration voltage and electron beam position have been determined by computer simulation.
– Engineering model has been built.
– The electron gun has been tested to get optimized parameters for required thin beam.
– Vibration test of some components such as the electron gun, electron current monitor, ion detector (a channel electron multiplier) and power supplies was done and their durability to withstand the vibration during launch of the rocket is confirmed.
– Vibration test of the engineering model has been done and weakness of support parts of the ring electrodes was found. The design of the support parts was modified and confirmed to withstand the vibration.
– Electronic circuits for control and monitoring of the instrument are designed and tested.The engineering model has been tested, and its capability of the energy distribution measurement of room temperature gas was confirmed.Designed a flight model based on the engineering model test results. It was manufactured and delivered.
