Using a fast time-of-flight mass spectrometer, a complete set of ions are detected for each impact, from a mass range of 1 (atomic hydrogen) up to a few thousand atomic mass units, encompassing all Ò€¦ For the first time mass spectra of negative ions are available for cometary particles. Unlike the spectra from interstellar particles they show only a few lines indicating small dust particles as their source.

The cometary and interstellar dust analyzer at comet 81p/wild 2 tions suggest that the sheets of ejected particles are several km thick at ~250 km from the nucleus and that dust. The cida instrument is a mass spectrometer, which separates ions' masses by comparing differences in their flight times. The operating principle of the instrument is the following: When a dust particle hits Ò€¦ The arrival times of the ions are digitized, and the mass spectra of the secondary ions are calculated from these time-of-flight spectra. Through the instrument commissioning, cosima took the very first Ò€¦ Using a fast time-of-flight mass spectrometer, a complete set of ions was detected for each impact, from a mass range of 1 (atomic hydrogen) up to a few thousand atomic mass units, encompassing all Ò€¦
