  In the frame­work of LAN­SCE Ac­cel­er­a­tor Mod­ern­iza­tion Pro­ject pre­lim­i­nary re­search, dur­ing eval­u­a­tion of crit­i­cal tech­nol­ogy el­e­ments it was found that the pro­posed RFQ de­sign had not yet been demon­strated ex­per­i­men­tally world­wide. Such an RFQ should com­bine the abil­ity of tra­di­tional light ion RFQs (i.e., [1]) and the flex­i­bil­ity of ac­cel­er­a­tion of pre-bunched beams, like RFQs for heavy ions [2]. The pro­posed RFQ should be able to ac­cel­er­ate H+ and H beams with 35-mA beam cur­rent from 100 keV to 3 MeV and at the same time pre­serve the pre­scribed macro-bunch beam time struc­ture re­quired by ex­per­i­ments. New al­go­rithms for RFQ geom­e­try gen­er­a­tion have been pro­posed, and op­ti­miza­tion al­go­rithms are being de­vel­oped at LANL. LAMP demon­stra­tion plans also in­clude de­vel­op­ment of a new set of elec­trodes for the ex­ist­ing RFQ at our Test Stand that will allow us to demon­strate the crit­i­cal tech­nol­ogy ahead of time in a lab­o­ra­tory ex­per­i­men­tal setup with low duty fac­tor and low en­ergy.
