An installation for intervention in a well, comprises a lower assembly comprising a neutron generator and a power source electrically connected to the neutron generator; a surface assembly comprising one or more safety devices, each safety device being either in a safe state or an unsafe state; and a communication module that connects the lower and surface assemblies. The surface assembly also comprises a surface transmitting device for transmitting data to the downhole assembly via the communication module including a first transmitter for transmitting an activating command, where the first transmitter transmits the activating command only if each of the safety device is in a safe state, and a second transmitter for transmitting a stopping command, where the second transmitter transmits the stopping command if one of the safety device is in an unsafe state.
