A quadrupole mass filter consisting of four parallel rods spaced equidistantly is a principal component of recent mass spectrometers due to the simple schematic and high capability to resolve the mass-to-charge ratio of ionized atoms or other charged particles. In spite of its simple physical geometry and obvious operating principle, ions behavior in the device is very complex to analyze. But it is still necessary to examine the possible degree of deviation from perfect operating conditions in the practical point of view. In this conference, ions transmission probabilities through a quadrupole mass filter will be presented. The probability are calculated with computer simulation at various initial ion conditions such as ion position, ion injection angle, ion velocity distribution and quadrupole mechanical misalignment. These calculated results on tolerance of each parameter will be helpful to improve the performance of quadrupole mass spectrometers.

The mass spectrometer, being an essential scientific instrument for uncovering the origin of the solar system and life, has been used since the early 1970s on board spacecraft to obtain information of neutral and ionized elements in the atmosphere and surface of the moon, planets, asteroids, and comets. According to the 4th Basic Plan for the Promotion of Space Development (2023-2027), Korea plans to conduct lunar landing in 2032 and Mars landing in 2045 as the core goals of the plan and focuses on developing the technologies required for unmanned robotic exploration missions. In this regard, it is crucial to develop the technology of a mass spectrometer, which is the most fundamental payload for space exploration for maximized scientific achievements, however never tried before in any domestic space missions. We describe in this paper the principle of a domestically developed quadrupole mass spectrometer, its prototype model, and the test results of its performance. We conclude this paper with intended future improvements.

우리나라의 첫 달 탐사선 다누리호가 달 궤도에 진입을 성공하면서 이후 화성 탐사와 같은 우리나라의 새로운 우주탐사 계획을 기대할 수 있게 되었다. 우리나라의 우주탐사 탑재체는 한정적인 분야에서만 개발되어 새로운 우주탐사 탑재체를 개발할 필요성이 있다. 국외에서는 우주탐사에 거의 기본적으로 탑재되는 장비로 질량분석기가 있으며, 탐사 대상의 대기와 휘발성 물질 관측과 더불어 유기물 분석을 통한 생명체 탐사까지 아우르는 매우 유용한 탑재체이다. 하지만 우리나라에선 우주탐사용으로 질량분석기 탑재체를 개발한 전적이 없으므로 앞으로의 우주탐사를 대비해 기술을 확보해야 할 필요가 있다. 그에 앞서 국외의 우주탐사용 질량분석기 탑재체의 과학적 성과를 살펴보고 동향을 파악해본다.
