Iontrap parameters

  • Ring-electrode inner radius: r0 = (cm)
  • Cap-electrode top-bottom interval: 2*z0 = (cm)
  • Trap voltage: 2*Vac = (kVp-p)
  • Trap frequency: (kHz)

Iontrap parameter results

  • D1 = 4.81E+06
    Vac=2.50E+03 V, r0=1.10E-02 m, Omega=9.42E+03 rad
  • D2 = 4.11E+03
    z0=7.80E-03 m

Possible specific charge range

0 < e/m < 0.23*r02*Omega2/Vac = 9.89E-01 (C/kg)
