Methods and devices enable coupling of a charged particle beam to a radio frequency quadrupole (RFQ). Coupling of the charged particle beam is accomplished, at least in-part, by relying on sensitivity of the RFQ to energies of the incoming charged particle beam. A portion of a charged particle beam, which has an initial energy outside a range of RFQ's acceptance energy values, is subjected to a field that modifies its energy to fall within the range of RFQ's acceptance energy values. Once the field is removed, the charged particle beam returns to the initial energy that is outside of the RFQ' range of acceptance energy values. In another configuration, a portion of a charged particle beam, which has an initial energy within the range of RFQ's acceptance energy values, is subjected to a field that modifies its energy to fall outside the range of acceptance energy values of the RFQ.
