Abstract
Penning Ion trap is an instrument where charged particles can be stored by means of quadrupolar electric field and high magnetic field. Motion of charged particle within the trap electrodes induces weak image signal which is detected by LC resonant circuit followed by a Low noise amplifier. To get a large voltage signal, the quality factor of the resonator should be very high. So, a high Q helical resonator is commonly used in ion trapping devices, as it offers considerably high Q (∼ 1000) in a small geometry. Resonating frequency of the resonator is selected based on the trap geometry and mass of trapped particle. For ion trapping system we have designed a 20 MHz helical resonator and studied its parameters through simulations.
