چکیده انگلیسی
We presents the results of an activity concerning the test of the Einstein Weak Equivalence Principle with an accuracy of about 5Â ÃÂ 10â15. The experiment will be performed in an “Einstein elevator” using a differential accelerometer with a final sensitivity of about 10â14Â gâ/Hz1/2. The differential accelerometer is spun about an horizontal axis at a frequency in the range 0.5-1Â Hz in order to modulate, during the free fall, the signal from a possible violation of the Equivalence Principle. In the paper the perturbing effects with the same signature of the possible violation are analyzed and constrained. The experimental results obtained in the laboratory with a first prototype of the differential accelerometer are discussed, comparing this results with those obtained using a new prototype.
