Design And Experimental Investigation Of Linear Ion Trap Driving Circuits

Ion traps have many applications in frequency standards, mass spectrometry,quantum information processing, and quantum simulation. The most common ion traps inused now are Paul traps. Trapping ions using a Paul trap require a stable, high voltage andlow noise radio frequency (RF) source. This requires the driving circuit of a Paul trap tohave two functions: amplification and narrow band-pass filtering, with low noise.In principle, we can use RLC resonance circuits as driving circuits. But in practice,for high precision measurement, we seldom use them, because these circuits have largernoises with lower Q. This thesis will introduce a new helical resonance circuit which hasadvantages such as simpler structure and higher Q.The resonance frequency of the constructed helical resonance circuit reaches25.59MHz, and the Q reches337. This not only meets the experiment requirement, but alsoreaches very high performance level. Construction tuning and testing of the helicalresonator is explained in this thesis. Final experimental results are also presented in thisthesis.
