Dust particle calibration of instrumentation for dust particle velocity and trajectory determination

摘要

In earlier reports, the development of polyvinylidene fluoride (PVDF) dust detectors were described, which have the capability for: (1) particle mass and velocity determination using thin PVDF sensors spaced a given distance apart; and (2) particle impact position determination using specially constructed two-dimensional position sensing PVDF dust detectors (x, y detectors). By combining these developments, space instrumentation capable of determining the mass, velocity, and trajectory of an incident dust particle was designed. In particular, for applications requiring high accuracy in trajectory determination, a dust-particle trajectory telescope using PVFD x, y detectors which will have this capability if the x, y impact coordinates to within /- 2 mm in x and y was described.
