Contamination control, safety and assurance • A. Bouabdellah
Contamination control • 3D cubes magnetic properties • The 3D cubes have some Nickel on their cover • Two modules have been tested in Technical University of Braunschweig (Germany): • P.A. module ref: DC4101 • Regulator module: ref: DC1101
Contamination control • Test set up: Detector (20 cm from DUT) D.U.T. To magnetometer Magnetizing and demagnetizing coils Spinning table
Contamination control • First measurement as is • Second measurement after 3G magnetization • Third after degaussing
Contamination control • Results:
Conclusion: • Small signal • Noisy environnement low measurement accuracy
