TL;DR: The MICROSCOPE satellite aims to test its validity at the 10^{-15} precision level, by measuring the force required to maintain two test masses exactly in the same orbit, by characterizing the relative difference in their free-fall accelerations.

TL;DR: The MICROSCOPE mission was designed to test the weak equivalence principle (WEP), stating the equality between the inertial and the gravitational masses, with a precision of 10^{-15} in terms of the Eötvös ratio as discussed by the authors .

TL;DR: In this article , the Eötvös parameter η(A,B) = 2aA−aBaA+aB for two test masses, made from platinum and titanium alloys, in a sequence of 19 segments lasting from 13 to 198 h down to the limit of the statistical error which is smaller than 10−14 for η (Ti, Pt) = [−1.5 ± 2.3 (stat) ± 1.5 (syst)] × 10−15.

Magnetron sputter process for inner cylinder coatings
TL;DR: In this article, a depositioning set-up for cylindrical permanent magnets is described, either inside a post magnetron PM, or at the ends of the hollow cylinders or sleeves that are to be coated.
