Electrical Properties of a Coaxial Electron-Ion Trap

Popis výsledku v původním jazyce

We present an electrical design for a radio-frequency trap for ions andelectrons. Our purpose is to research sub-Kelvin ion-electron plasma. In addition, thedevice has various potential applications in quantum technology. However, phenomenalike electric stray field, phase shift on trap electrodes, and radiative heating can causemajor disturbances for the trapped quantum system. Two latter ones can be suppressedby using a high-quality resonator as a trapping electrode, but coaxial resonators, whichcould offer an enhanced quality factor, have been rarely seen in particle trapping.In our coaxial trap, there are two different paths to apply trapping signals: an input pin,capacitively coupled to the resonator; and two endcaps. The trap depth has been foundto vary less than 1.5 % when changing the input pin length by 1 mm. The distancebetween the pin and the resonator of 1 mm, allowed by the manufacturing limit, hasproven to be sufficient according to simulations. It has been computed to allow theresonator to operate with a quality factor of 15 000, seven times more than in previouscomparable designs. This would enable us to operate the trap with relatively low inputpower, decreasing device heating and improving the trap performance.
