Cosmic mass spectrometer

Hypervelocity microparticle impact studies using a novel cosmic dust mass spectrometer

Micron-sized iron and copper particles accelerated to 2-20 km/s in a 2 MV Van de Graaff electrostatic accelerator tested the performance of our recently-developed cosmic dust mass spectrometer. This compact in situ dust analyzer, known as the Dustbuster, is designed to determine the elemental composition of cosmic dust particles through impact ionization and subsequent time-of-flight mass spect...

The Dustbuster: A Compact Time-of-flight Mass Spectrometer for Cosmic Dust Analysis

Macromolecular ion accelerator mass spectrometer.

We present a newly developed macromolecular ion accelerator mass spectrometer that combines a dual-ion-trap device and a macromolecular ion accelerator (MIA) to achieve the capability of analyzing samples with a mixture of large biomolecules. MIA greatly increases detection efficiency. The dual ion trap includes a quadrupole ion trap (QIT) and a linear ion trap (LIT) in tandem. The dual ion tra...

The Cosmic Causal Mass

In order to provide a better understanding of rotating universe models, and in particular the Gödel universe, we discuss the relationship between cosmic rotation and perfect inertial dragging. In this connection, the concept of causal mass is defined in a cosmological context, and discussed in relation to the cosmic inertial dragging effect. Then, we calculate the mass inside the particle horiz...

A quadrupole mass spectrometer for resolution of low mass isotopes.

The qualitative and quantitative identification of low mass isotopes in the mass range 1-6 u poses certain difficulties when attempting to achieve the required resolution with an instrument suitable for deployment within a process environment. Certain adjacent species present in the process sample (HT and D(2)) require a resolution greater than 930 to achieve an accurate measurement. We demonst...
