The LISA test masses must be kept free of stray acceleration noise to within 3 × 10-15 m s-2 Hz-1/2 in order to obtain the low-frequency gravitational wave sensitivity goal. The LISA technology package (LTP) is a dedicated ESA flight experiment for testing the drag-free control technology that must ensure purity of free fall in the LISA mission. We present here a brief description of the LTP experimental configuration, specific measurements to be performed and the requirements that must be met in order to demonstrate the LTP stray acceleration upper limit goal of 3 × 10-14 m s-2 Hz-1/2 at 1 mHz.

Abstract
The LISA test masses must be kept free of stray acceleration noise to within 3 × 10-15 m s-2 Hz-1/2 in order to obtain the low-frequency gravitational wave sensitivity goal. The LISA technology package (LTP) is a dedicated ESA flight experiment for testing the drag-free control technology that must ensure purity of free fall in the LISA mission. We present here a brief description of the LTP experimental configuration, specific measurements to be performed and the requirements that must be met in order to demonstrate the LTP stray acceleration upper limit goal of 3 × 10-14 m s-2 Hz-1/2 at 1 mHz.File in questo prodotto:
