Abstract

The neutral sodium atoms have been slowed down to the trap depth by using a Zeeman slower and trapped by the magneto-optical method. The density and the temperature of the trapped atoms are measured, and the frequency region where the trap is available is represented. We controlled the flux of slowed atoms by varying the slowing beam intensity, and we measured the increasing and decreasing rate of trapped atoms. We show that the difference between the increasing and decreasing rate of trapped atoms result from the loss proportional to $N_2$.

Zeeman 감속기를 사용하여 감속한 나트륨 원자를 자기광학적 방법으로 포획하였다. 자기광학적 방법으로 포획된 원자의 개수와 온도를 측정하고, 포획이 가능한 포획광의 주파수 영역과 펌핑광의 주파수영역을 나타내었다. Zeeman 감속기로부터 유입하는 원자의 양을 조절한 경우에 원자 개수의 증가율과 감소율을 측정하고, 이들 차이로부터 $N_2$에 비례하는 손실에 대하여 논의하였다.
