Re­cently a new ra­di­a­tion pro­tec­tion in­ter­lock sys­tem has been es­tab­lished at the Darm­stadt su­per­con­duct­ing lin­ear elec­tron ac­cel­er­a­tor S-DALINAC [*]. It pre­vents the staff from en­ter­ing ra­di­a­tion pro­tec­tion areas dur­ing op­er­a­tion and al­lows a sys­tem­atic scan­ning of these areas for work­ers be­fore run­ning the ac­cel­er­a­tor. As an ex­ten­sion of the new in­ter­lock, a new dose rate mon­i­tor­ing sys­tem has been de­vel­oped using PIN diodes and self-made ion cham­bers. These de­tec­tors will be used to per­fom on­line dose rate mea­sure­ments in order to switch au­tomti­cally the sta­tus of il­lu­mi­nated ra­di­a­tion pro­tec­tion pan­els, which show the cur­rent level of pro­tec­tion area. Fur­ther­more, they will be used to char­ac­ter­ize sys­tem­at­i­cally the ra­di­a­tion fluxes in­side the ac­cel­er­a­tor fa­cil­ity and to sup­port the beam di­ag­nos­tics. The read­out elec­tron­ics con­sists ofμcon­trollers with eth­er­net in­ter­faces using TCP/IP based se­r­ial com­mu­ni­ca­tion. The data ac­qui­si­tion is in­te­grated into the EPICS based con­trol sys­tem. First re­sults of the com­mis­sion­ing will be pre­sented.
