▁beam ▁intensity , ▁was ▁constantly ▁growing , ▁reaching ▁by ▁February ▁ 2 0 2 0 ▁the ▁power ▁of ▁ 5 1 5   k W ▁and ▁a ▁total ▁number ▁of ▁accum ulated ▁pro tons ▁on ▁target ▁of ▁ 3 . 6 4 × 1 0 2 1 ▁pro tons ▁ ▁with ▁ 5 5 % ▁of ▁data ▁in ▁neut r ino - mode ▁and ▁ 4 5 % ▁in ▁ant ine ut r ino - mode . ▁ ▁In ▁April ▁ 2 0 2 0 , ▁T 2 K ▁collaboration ▁published ▁results ▁strongly ▁const ra ining ▁the ▁ δ CP ▁phase . ▁The ▁results ▁reject ▁at ▁ 9 5 % ▁confidence ▁the ▁hypothesis ▁of ▁no ▁CP ▁viol ation ▁( including ▁the ▁possibility ▁of ▁ δ CP ▁equal ▁to ▁ π ). ▁The ▁results ▁also ▁reject ▁at ▁the ▁ 3 σ ▁( 9 9 . 7 %) ▁significance ▁level ▁almost ▁half ▁of ▁the ▁possible ▁values ▁of ▁this ▁parameter ▁and ▁give ▁a ▁strong ▁hint ▁that ▁CP ▁viol ation ▁may ▁be ▁large ▁in ▁the ▁neut r ino ▁sector . ▁ ▁Future ▁plans ▁ ▁The ▁T 2 K ▁experiment ▁is ▁expected ▁to ▁operate ▁in ▁the ▁current ▁form ▁until ▁the ▁end ▁of ▁ 2 0 2 0 . ▁In ▁ 2 0 2 1 ▁a ▁major ▁upgrade ▁of ▁the ▁neut r ino ▁beam line ▁and ▁the ▁N D 2 8 0 ▁near ▁det ector ▁will ▁be ▁performed . ▁From ▁ 2 0 2 2 ▁till ▁ 2 0 2 6 ▁neut r ino ▁data ▁will ▁be ▁taken ▁within
