The LTP (LISA testflight package), to be flown aboard the ESA/NASA LISA pathfinder mission, aims to demonstrate drag-free control for LISA test masses with acceleration noise below 30 fm s-2 Hz-1/2 from 1-30 mHz. This paper describes the LTP measurement of random, position-independent forces acting on the test masses. In addition to putting an overall upper limit for all source of random force noise, LTP will measure the conversion of several key disturbances into acceleration noise and thus allow a more detailed characterization of the drag-free performance to be expected for LISA.

Abstract
The LTP (LISA testflight package), to be flown aboard the ESA/NASA LISA pathfinder mission, aims to demonstrate drag-free control for LISA test masses with acceleration noise below 30 fm s-2 Hz-1/2 from 1-30 mHz. This paper describes the LTP measurement of random, position-independent forces acting on the test masses. In addition to putting an overall upper limit for all source of random force noise, LTP will measure the conversion of several key disturbances into acceleration noise and thus allow a more detailed characterization of the drag-free performance to be expected for LISA.File in questo prodotto:
