Optical pumping cesium beam tubes
WebApr 12, 2024 · The optical repumping beam is resonant with 5 S1/2, F = 1 to 5 P1/2, F′ = 2 transition to pump most of the atoms to F = 2 states. Both optical pumping and repumping beams are split and sent to the two sensors (S a and S b) of the gradiometer. WebCaesium reference tubes suitable for national standards currently last about seven years and cost about US$35,000. Primary frequency and time standards like the United States Time Standard atomic clocks, NIST-F1 and NIST-F2, use far higher power. [31] [43] [44] [45] Block diagram [ edit]
