  1. An experiment to test NEWTON in the laboratory at very small acceleration with W. Bartel, A. Glazov, B. Löhr, E. Lohrmann C. Niebuhr, S. Schubert, E. Wünsch DESY and H. Meyer ; Univ. Wuppertal

  2. Measurement Procedure • Resonance Frequency is about 21 GHz • Take 5 points on the resonance • Fit for amplitude, with and mean • Do it twice a second • Take tilt, temperature, barometer • Get seismic noise • Get height of the waves in the N-Sea

  3. Big G? • In 8/2010 a new determination was published by Parks and Faller • The number is - 300 ppm off the nominal • Value, but 10 sigma from the best value • Sofar • SHOULD BE CLARIFIED

  4. DM problem • It is nown since long that stars in galaxies • And galaxies in clusters do not move following Newton (DM-Problem), • Zwicky, and Rubin • Solution proposed by Milgrom proposes changing Newtons law at small acceleration • Only one Parameter a(0) = 1.2x10e-10 m/sec(2)

  5. 17

  6. In the future • Get a more accurate measurementof G • Improve on errors at small masses • (accelerations at a(0) and below) • It may require choosing a more quiet place
