Query: 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.
