As part of the LHC In­jec­tor Up­grade pro­gram a com­plete over­haul of the Super Pro­ton Syn­chro­tron Ra­dio-Fre­quency (RF) sys­tem took place. New cav­i­ties have been in­stalled for which the solid-state tech­nol­ogy was cho­sen to de­liver a com­bined RF power of 2 MW from 2560 RF am­pli­fiers. This strat­egy promises high avail­abil­ity as the sys­tem con­tin­ues op­er­a­tion when some of the am­pli­fiers fail. This study quan­ti­fies the op­er­a­tional avail­abil­ity that can be achieved with this new in­stal­la­tion. The eval­u­a­tion is based on a Monte Carlo sim­u­la­tion of the sys­tem using the novel Avail­Sim4 sim­u­la­tion soft­ware. A model based on life­time es­ti­ma­tions of the RF mod­ules is com­pared against data from early op­er­a­tional ex­pe­ri­ence. Sen­si­tiv­ity analy­ses have been made, that give in­sight to the cho­sen op­er­a­tional sce­nario. With the in­creas­ing use of solid-state RF power am­pli­fiers, the find­ings of this study pro­vide a use­ful ref­er­ence for fu­ture ap­pli­ca­tion of this tech­nol­ogy in par­ti­cle ac­cel­er­a­tors.
