Experimental study of a r.f. quadrupole ion trap supplied with a periodic impulsional potential

In continuation of a previous theoretical work, we confirm experimentally the possibility of confining ions in a r.f. quadrupole trap supplied with an impulsional voltage. We have obtained the stability diagram of the trap corresponding to confined Xe + ions. This diagram shows a zone of optimum con...

Description
Summary:In continuation of a previous theoretical work, we confirm experimentally the possibility of confining ions in a r.f. quadrupole trap supplied with an impulsional voltage. We have obtained the stability diagram of the trap corresponding to confined Xe + ions. This diagram shows a zone of optimum confinement. Then, we have compared the confinement efficiency of the trap, when supplied by a sinusoidal or impulsional voltage, for two equivalent points of trap operation located in their corresponding stability diagram.
