The ap­pli­ca­tion of pho­tonic crys­tals to re­al­ize an on-chip elec­tron beam source for fun­da­men­tal ra­di­a­tion bi­ol­ogy is highly in­ter­est­ing for a num­ber of ap­pli­ca­tions. The unique com­bi­na­tion of nanome­ter beam size and at­tosec­ond-short pulses has a very promis­ing po­ten­tial for use in mi­cro­scopic and ul­tra-fast analy­ses of dam­age and re­pair of ra­di­a­tion-ir­ra­di­ated DNA and chro­mo­somes. Sim­u­la­tions stud­ies in­di­cate an out­put elec­tron beam en­ergy, beam in­ten­sity and de­vice size of the order of MeVs, fCs and a few cm, re­spec­tively. In this con­tri­bu­tion, first re­sults from nu­mer­i­cal stud­ies into the de­sign of such com­pact ac­cel­er­a­tor struc­ture are pre­sented. The di­men­sions of a novel dual grat­ing-based ac­cel­er­a­tion struc­ture are shown to­gether with the es­ti­mated laser pa­ra­me­ters. Fi­nally, a sys­tem con­sist­ing of an elec­tron in­jec­tor and multi-stage ac­cel­er­at­ing struc­tures is pro­posed, which cor­re­sponds to a minia­tur­ized op­ti­cal lin­ear ac­cel­er­a­tor.
