Stray light in the LISA instrument: characterization and modelling of the coherent perturbation of a homodyne interference

Lintz, Michel Khodnevych, V. Pace, S

In the LISA mission, the presence of stray light is a concern since a perturbation of the heterodyne phase measurement at the level of several µradian can give rise to significant noise in the LISA gravitational wave measurement. The perturbation scales as the square root of the stray light to nominal beam optical power ratio. Reaching very low...

Radiation Tolerance of Low-Noise Photoreceivers for the LISA Space Mission

Colcombet, P Dinu-Jaeger, N Inguimbert, C

This study investigates the effects of space environmental radiation on the performance of InGaAs Quadrant Photodiodes (QPDs) and assesses their suitability for the Laser Interferometer Space Antenna (LISA) mission. QPDs of 1.0, 1.5 and 2.0 mm have been irradiated with 20 and 60 MeV protons, 0.5 and 1 MeV electrons, and Co$^{60}$ gamma. An...
