Abstract
A cryogenic torsion balance method is suggested to measure the residual quadrupole moments of the STEP test masses directly. The individual masses are placed on a torsion balance and the torque exerted by a rotating set of source masses is analysed. Conservatively, assuming a torque sensitivity of 10(-13) Nm, it appears that a quadrupole moment of 10(-7) kg m(2) can be detected.
