Introduction: The Rosetta Orbiter Spectrometer RTOF. The RTOF is characterized by an extended for Ion and Neutral Analysis (ROSINA) is an orbiter mass range from 1 up to > 300 amu/e in order to payload instrument onboard the ROSETTA spacecraft identify organic material, e.g., polyaromatic that was successfully launched in March 2004 by the hydrocarbons. The sensor weights 15 kg and consumes European Space Agency. The ROSINA instrument about 30 W. The high sensitivity of the RTOF sensor is package is designed to determine the elemental, essential with respect to the pressure range that is isotopic, and molecular composition of the atmosphere expected when Churyumov-Gerasimenko is at 3 AU of comet 67P/Churyumov-Gerasimenko. where measurements are activated. The expected water ROSINA Characteristics: The instrument production rates at perihelion, during peak activity, and package ROSINA consists of two mass spectrometers at 3 AU at comet Churyumov-Gerasimenko are given and one pressure sensor. The mass spectrometers are in table 1. the Double Focussing Mass Spectrometer (DFMS) and the Reflectron Time-Of-Flight mass spectrometer Tab. 1: Expected water production rate and the (RTOF) that are both designed to analyze cometary corresponding pressure at 2 km from the nucleus for neutral gases and cometary ions. The third sensor, the comet Churyumov-Gerasimenko [4]. COmetary Pressure Sensor (COPS), consists of a Heliocentric Q(H 2O) H2O density Pressure pressure gauge assembly. These three sensors will distance [s -1] [cm -3] @ 2 [mbar] measure the neutral gas and the ion composition in the km cometary environment as a function of the heliocentric Perihelion 4.1 x 10 27 2.0 x 10 11 6.0 x 10 -6 distance to the comet [1]. The Data Processing Unit (1.3 AU) (DPU) controls all three sensors and is fully redundant. Peak activity 1.0 x 10 28 8.0 x 10 11 2.5 x 10 -5 The characteristic features of the three sensors are 3 AU 1.0 x 10 23 1.0 x 10 7 1.0 x 10 -10 described in more detail below: DFMS. The DFMS is a very compact state of the An advantage of the RTOF sensor is that a full art high-resolution double-focussing mass mass spectrum of the entire mass range (1-300 amu/e) spectrometer [2] realized in the Nier-Johnson that is only limited by the signal accumulation memory configuration [3]. The sensor weights 16 kg and the is recorded within 100 µs. The mass resolution in the power consumption averages 22 W. The DFMS is a triple reflection mode is m/ ∆m > 4500 at the 50% peak high resolution mass spectrometer with a large height. DFMS and RTOF complement one another. dynamic range and good sensitivity. It covers a mass COPS. The COPS weights 1.7 kg and consumes 7 range of 12-140 amu/e and has a mass resolution of W. It consists of two ionization gauges to determine m/ ∆m > 3000 at the 1% peak height which corresponds the gas dynamics of the comet. One gauge is a nude to > 7000 at the 50% level. This allows separation of, hot filament extractor type Bayard Alpert ionization 13 12 e.g., C and CH. With an integration time of gauge [5]. It measures the total particle density with a typically one second the recording of a whole mass nitrogen sensitivity of about 20 mbar -1 at 100 µA. The spectrum measured with the Channel Electron other gauge, a closed ionization gauge, with its Multiplier (CEM) detector from 12 to 140 amu/e takes opening facing towards the comet, measures the approximately two hours. The mass resolution of the molecular flow from the comet. Combining the results DFMS is high enough to measure interesting isotopic from both gauges and the known spacecraft orientation 14 + 15 + ratios of, e.g., the two
