Ul­tra-high gra­di­ents which are crit­i­cal for fu­ture ad­vances in high-en­ergy physics, have so far re­lied on plasma and di­elec­tric ac­cel­er­at­ing struc­tures. While bulk crys­tals were pre­dicted to offer un­par­al­leled TV/m gra­di­ents that are at least two or­ders of mag­ni­tude higher than gaseous plas­mas, crys­tal-based ac­cel­er­a­tion has not been re­al­ized in prac­tice. We have de­vel­oped the con­cept of nanoplas­monic crunch-in sur­face modes which uti­lizes the tun­abil­ity of col­lec­tive os­cil­la­tions in nano­ma­te­ri­als to open up un­prece­dented tens of TV/m gra­di­ents. Par­ti­cle beams in­ter­act­ing with nano­ma­te­ri­als that have vac­uum-like core re­gions, ex­pe­ri­ence min­i­mal dis­rup­tive ef­fects such as fil­a­men­ta­tion and col­li­sions, while the beam-dri­ven crunch-in modes sus­tain tens of TV/m gra­di­ents. More­over, as the ef­fec­tive aper­tures for trans­verse and lon­gi­tu­di­nal crunch-in wakes are dif­fer­ent, the lim­i­ta­tion of tra­di­tional scal­ing of struc­ture wake­fields to smaller di­men­sions is sig­nif­i­cantly re­laxed. The SLAC FACET-II ex­per­i­ment of the nano2WA col­lab­o­ra­tion will uti­lize ul­tra-short, high-cur­rent elec­tron beams to ex­cite non­lin­ear plas­monic modes and demon­strate this pos­si­bil­ity.
