Description
I have analytically derived low-voltage approximations of tunes in RFQ with multiple radio frequencies to increase the efficiency of finding conditions of betatron resonances for isobar separation. The SCRIT (Self-Confining RI Ion Target) electron scattering facility has been aiming at the 132Sn-electron scattering, which requires eliminating an isobar, 132Sb, from the ion source. To achieve such a separation with a mass sensitivity of 0.002%, Pf. Wakasugi proposes utilizing a sharp betatron resonance in MRFQ (RFQ with Multiple radio frequencies). The current way to find parameters causing the resonance is only numerical calculations with possible parameters, which is inefficient and impractical. To acquire the values of tunes more expeditiously than numeric operation, I have analytically computed low voltage approximations of tunes up to the second order by direct calculation of the transition matrix in MRFQ. My succeeding objective is to refine the approximation and obtain the mass sensitivity of each resonance.
