Notes:
Insertion of an LC single-stage notch filter (of the shunt variety) between the output of a quadrupole mass spectrometer and a fast current amplifier greatly attenuates the rf noise typically present on the signal output. The 2.5-MHz rf was significantly reduced with negligible interference of the 1-μs resolved time of flight (TOF) work. Also presented is the fast current amplifier design.
