摘要：
DECIGO Pathfinder is the first milestone mission for DECIGO, a future gravitational wave antenna. In DPF, residual gas noise acting on the test mass is estimated to increase and exceed the requirement for force noise of 1 x 10(-15) N/root Hz due to geometry of the test-mass module. We performed a Monte Carlo simulation to calculate the residual gas noise and found that the engineering model of the test-mass module cannnot satisfy the requirement. To reduce the gas noise, we present revised geometry of the test-mass module using comb-like electrodes.
