  An ac­cel­er­a­tor-based boron neu­tron cap­ture ther­apy (BNCT) has been stud­ied in­ten­sively in re­cent years as one of the new can­cer ther­a­pies after many clin­i­cal re­search with nu­clear re­ac­tors. In the iBNCT pro­ject, the ac­cel­er­a­tor con­fig­u­ra­tion con­sists of an RFQ and a DTL which have proven achieve­ments in J-PARC. Mean­while, a high duty fac­tor is re­quired to have a suf­fi­cient ther­mal neu­tron flux needed by BNCT treat­ments. After a fail­ure of the kly­stron power sup­ply oc­curred in Feb. 2019, beam op­er­a­tion was re­sumed in May 2020. To date, an av­er­age cur­rent of about 2 mA with the beam rep­e­ti­tion rate of 75 Hz has been achieved with sta­ble op­er­a­tion. Ir­ra­di­a­tion tests with cells and mice are on­go­ing to­gether with char­ac­ter­is­tic mea­sure­ments of the neu­tron beam. In par­al­lel with that, we have been grad­u­ally im­prov­ing the ac­cel­er­a­tor cool­ing-wa­ter sys­tem for fur­ther sta­bil­ity. In this con­tri­bu­tion, the pre­sent sta­tus and prospects of the iBNCT ac­cel­er­a­tor are re­ported.
