Paper Abstract

We report on the latest iteration of the baseline opto-mechanical architecture of the LISA instru- ment, which has been developed within the current LISA Mission Formulation study under ESA con- tract. The collective features of the current architec- ture have been consolidated in an extensive trade of various alternative payload configurations, including variants with only one active proof mass per space- craft and the application of “In-Field Pointing” for accommodation of constellation breathing.

With respect to the original configuration [1], the newly established architecture most notably distin- guishes itself by the use of an off-axis telescope and a “non-frequency-swap” science interferometer for stray light mitigation, as well as the implementa- tion of ancillary pathlength metrology in terms of an “Optical Truss” and Point Ahead Angle sensing.
