Compact Atomic Clocks (Rubidium) with ultra low phase noise and excellent long term stability


About This PhD Project

Project Description

The aims of this project will be to develop compact Atomic Clocks (Rubidium) with ultra low phase noise and excellent long term stability. Introduction: Atomic clocks offer very high long term stability and accuracy by using hyperfine energy level transitions which occur at microwave frequencies. These hyperfine transitions are very stable and accurate and therefore International time is defined using atomic clocks which are compared around the world. The definition for a second is currently based on transitions in Caesium.

Sophisticated communications and satellite systems (including GPS) often use small atomic clocks to maintain accuracy. It is this area of high performance compact atomic clocks that we wish to investigate here.
