Space Chemistry Lab

A high-level assessment of the instruments already established is first provided, given in Table 1 below, Table 1: Summary of capability and function of the various assembled instruments in the Space Chemistry Laboratory

INSTRUMENT PRIMARY CAPABILITY/FUNCTION

GUIDED-ION BEAM Enables studies of ion-neutral collision dynamics at user-selected laboratory energies between 0.1 and 300 eV. Typical detection is via quadrupole mass spectrometry and ions are confined in double octopole system.

ION-NEUTRAL CHEMI-

LUMINESCENCE

DETECTOR

Quantifies light emission from ion-neutral collisions at user-selected laboratory energies between 5 and 10,000 eV. Optical detection systems are available in vacuum ultraviolet, visible, near infrared and MWIR/LWIR.

ELECTROSPRAY

THRUSTER MASS

SPECTROMETER

Characterizes ion composition, current density, mass flow and kinetic energy of electrospray thruster plumes. Utilizes a Faraday cup, quartz crystal microbalance and quadrupole mass spectrometer for detection.

REFLECTRON TIME-

OF-FLIGHT MASS

SPECTROMETER

Provides high-resolution, multiplexed mass analysis of ion beams from an electrospray (or other) source through orthogonal extraction time-of-flight mass spectrometry. Detection currently accomplished via microchannel plates.

O-ATOM SURFACE

CONVERSION
