FAST Time of Flight Energy Angle Mass Spectrograph (TEAMS) Energy-Pitch Angle Distributions, Level 2 (L2), 5 s Data
Listed in NASA Data Portal
Fast Auroral SnapshoT Explorer, FAST, Time-of-flight Energy Angle Mass Spectrograph, TEAMS, Level 2 Energy-Pitch Angle Distributions TEAMS instrument is a high sensitivity mass resolving spectrometer with an instantaneous 360° field of view.
Description
It is designed to measure the full three-dimensional distribution function of ions. TEAMS selects the incoming ions according to energy per charge in the range from 1.2 eV/q to 12 keV/q by electrostatic deflection in a toroidal section analyzer with subsequent acceleration up to 25 keV/q and time-of-flight, TOF, analysis.
For each individual ion the instruments measures the energy per charge (electrostatic analyzer), the mass per charge (TOF analyzer), the incidence azimuthal angle (given by spacecraft spin at 5.6° or 11.2° resolution), and the incidence polar angle (given by the 22.5° sectoring in the TOF unit). Depending on the measurement mode the full energy sweep is performed 32 or 64 times per spin period thus providing a 2-D cut through the distribution function in polar angle every 78 ms or 156 ms.

One complete 3-D ion distribution function is obtained in half a 5 s spin period. The instrument axis of symmetry is perpendicular to the spacecraft spin axis and the spacecraft surface. TEAMS operates in a number of different data acquisition modes.
The Survey Distribution mode samples H°, O°, He°, and He°² with high angular (64 bin) and energy (48 bin) resolution. Time resolution can be as low as 80 ms (slow survey) and as high as 10 ms (fast survey). The High Mass Distribution mode uses a high mass (64 bin) resolution to identify minor species with lower resolution angular and energy resolution with 16 bins for each.
The High Mass Distribution mode time resolution varies from 80 ms (slow) to 20 ms (fast). Burst mode provides data for the four major ion species with the highest time resolution (0.08 ms) with 16 angle bin and 48 energy bin resolution. Additional measurement modes are geared towards the Pole Channels, Monitor Rates, and pulse height analysis, PHA, events.
