The Trigger and Data Acquisition system of the N-NBAR experiment at the Institute Laue-Langevin at Grenoble is presented, together with CAMAC modules especially designed for this experiment. The trigger system is organized on three logical levels; it works in the presence of a high level of beam induced noise, without beam pulse synchronization, looking for a very rare signal. The data acquisition is based on a MicroVaxII computer, in a cluster with 4 VaxStations, interfaced to CAMAC and uses a modified version of the DAQP software developed at CERN. The system has been working for a year with high efficiency and reliability.

Abstract
The Trigger and Data Acquisition system of the N-NBAR experiment at the Institute Laue-Langevin at Grenoble is presented, together with CAMAC modules especially designed for this experiment. The trigger system is organized on three logical levels; it works in the presence of a high level of beam induced noise, without beam pulse synchronization, looking for a very rare signal. The data acquisition is based on a MicroVaxII computer, in a cluster with 4 VaxStations, interfaced to CAMAC and uses a modified version of the DAQP software developed at CERN. The system has been working for a year with high efficiency and reliability.
