A compact setup for loading magneto-optical trap in ultrahigh vacuum environment

We have developed a compact setup which enables loading a magneto-optical trap (MOT) in ultra-high vacuum (UHV) environment. Nearly $1\times {10}^8$ atoms of ${}^{87}Rb$ are trapped in the MOT at $\sim 2\times {10}^{-10}$ Torr base pressure in the chamber. After the MOT loading, we have successfully demonstrated working of quadrupole magnetic trap in this chamber with a lifetime of $\sim 8$ s
