    "abstract": "There are applications, which require MeV-range multiple-beams consisting of\na large number of identical highly packed beamlets. The multiple-beam RFQ\n(MB-RFQ) arranged as a matrix array of longitudinal rod-electrodes is\nappropriate candidate. A configuration of MB-RFQ resonator should ensure\nidentical quadrupole fields in every accelerating channel. The MB-RFQ\nresonators based on TEM transmission lines are studied. The resonators are\ndesigned by a periodical multiplication of a 4-rod unit cell in transverse\ndirection. To understand fields of resonator the normal mode technique is\napplied. Novel configurations of MB-RFQ resonators based on these normal modes\nare generated. The RF properties of resonators are verified with computer\nsimulations done with MAFIA code. Beam dynamics study for the initial 400-keV\nMB-RFQ has been performed using PARMTEQ code. The MB-RFQ parameters and the\nresults of beam dynamics simulations are presented. The calculated beam\ntransmission is 33% at injection of 50-keV, 20mA deuteron beam.",
