摘要: An ion trap for a mass spectrometer has conductive central electrode with an aperture extending from first open end to second end. A cap is disposed proximate the thereby forming intrinsic capacitance between and electrode. circuit couples reference potential. signal source generating AC coupled excitation impressed on in response voltage division of by circuit.
