  TRI­UMF ISAC ac­cel­er­a­tor com­plex is in con­sists of ISAC-I room tem­per­a­ture linac and ISAC-II su­per­con­duct­ing linac struc­ture. ISAC-I linac has sev­en­teen RF sys­tems in op­er­a­tion for about twenty years, and ISAC-II linac has forty su­per­con­duct­ing QWR RF cav­i­ties in op­er­a­tion for more than ten years. A small ISAC booster 3-gap struc­ture at 11.78 MHz lo­cated in up­stream of RFQ has been de­signed and in­stalled for en­ergy match­ing to RFQ. A slid­ing mode ex­tremum seek­ing con­trol for LLRF con­trol was de­vel­oped and im­ple­mented in op­er­a­tion. Six of DTL sys­tems have been work­ing in the con­trol mode. Two of them had been com­mis­sion­ing and in op­er­a­tion one and half year re­li­ably. RFQ, two more DTL sys­tem, HEBT re­buncher and DSB buncher sys­tem will be up­graded in the slid­ing mode con­trol soon. Twenty ISAC-II SBC su­per­con­duct­ing cav­ity RF power am­pli­fiers were up­graded from YV-229 tri­ode tube am­pli­fier into solid state am­pli­fier(SSA). The pro­to­type and four SSAs have been com­mis­sioned in 2017 and in op­er­a­tion suc­cess­fully. The rest of 16 SSA have been tested in RF lab and in­stalled for op­er­a­tion at the mid of this year.
