Abstract :
This paper describes a new determination of the Newtonian gravitational constant, G. Since our last compensated measurement of G, modifications have been made to the apparatus and operating procedures to further identify possible measurement errors and improve the uncertainty. Our latest value and its uncertainty is presented at the conference.
