Due to the collision-shift effect, helium permeation into the vapor cell causes a time-dependent frequency drift in rubidium atomic clock. To quantify this shift, a cylindrical vapor cell with dimensions of 1.8 cm in diameter, 1.6 cm in height, and 1

According to General Relativity Theory (GRT), by comparing the frequencies between two precise clocks at two different stations, the gravity potential (geopotential) difference between the two stations can be determined due to the gravity frequency s

Abstract The gravitational redshift (GR), as predicted by Einstein’s general theory of relativity, posits that two identical clocks situated at different gravitational potentials will tick at different rates. In this study, we explore the impact of

Driven by the demand for satellite navigation and deep space exploration, the performance of lamp-pumped rubidium atomic clock has been greatly improved, and its short-term frequency stability has reached the level of a small coefficient of 10-13τ -
