Supervisor: Dr C.C.Speake

We are currently conducting two programmes in experimental gravitation using our newly developed superconducting torsion balance. Our test of macroscopic time-reversal symmetry has been through a development phase and we have very promising preliminary results. We will shortly enter into a second phase of measurements after some innovative modifications. This experiment is already placing new constraints on particles that have been postulated by theorists that couple quantum mechanical spin to matter. The second programme aims at a precision determination of the Casimir force and a test of the inverse square law of gravitation at short range. This project is at a design and manufacturing stage with first results expected within a year. This is an exciting and rewarding field of study that is at the frontiers of both experimental and theoretical physics.
