(author), TNO Industrie en Techniek (author)The primary goal of the LISA mission is the detection of gravitational waves from astronomical sources in a frequency range of 10-4 to 1 Hz. This requires operational stabilities in the picometer range as well as highly predictable mechanical distortions upon cooling down, outgassing in space, and gravity release. In March 2011 ESA announced a...conference paper 2012

Groen, W.A. (author), Prijs, K. (author), Saeed, S. (author), TNO Industrie en Techniek (author)In general, it has been reported that the piezoelectric properties in multilayer actuators decrease for layer thicknesses below 20 microns. This has been investigated for PXE55 which is a material based on PLZT-Pb(Mg 1/2W1/2)O3 and PG01 which is a low sintering version of this material. Results show that for the standard PXE55 material the...conference paper 2010
