GINGER

GINGER (Gyroscopes IN GEneral Relativity), based on an array of large dimension ring laser gyroscopes, is aiming at measuring in a ground laboratory the gravito-electric and gravito-magnetic effects (also known as De Sitter and Lense-Thirrings effect), foreseen by General Relativity. The sensitivity depends on the size of the RLG cavities and the cavity losses, considering the present sensitivity, and assuming the total losses of 6 ppm, with 40m perimeter and 1 day of integration time sensitivity of the order of frad/s is attainable. The construction of GINGER is at present under discussion.
