Description

A space proposal for precisely measuring Casimir force and its thermal effect is introduced, which is based on an electrostatic space accelerometer and a picogravity satellite. Two 4 x 4 cm2 parallel gold plates are used as test masses with a separation of 5 to 20 μm. The Casimir force and its thermal effect between the two plates are calculated and the feasibility of our new proposal is discussed. Our analyses indicate that the expected effects could be demonstrated with 0.1 ～ 1% accuracy in our proposal.
