Abstract :
We present a current status of an atomic gravimeter, which is based on Mach-Zehnder-type atom interferometer using stimulated Raman transition, developing at KRISS. Cooling beams with (111) geometric configuration was used for magnetic optical trap (MOT). Rubidium87 (Rb87) atoms are trapped and cooled in MOT. Temperature of the trapped atoms was measured to be about 1.7μK by time of flight measurement after a deep cooling.
