Abstract :
Summary form only given, as follows.We describe the progress made to our measurement of the Newtonian gravitational constant since the 1994 CPEM. Changes to the apparatus include: a new suspended mass and torsion fibre and improvements to the calibration of the electrometer. This paper describes these changes and presents our latest result and its uncertainty.
