Type of neutron detector BF3 Type of signal cable Tnaxial

Location of pulse preamplifier In amplifier cabinet at control room Location of pulse amplifier In amplifier cabinet at control room Distance between pulse amplifier and preamplifier 2 ft Distance between neutron detector and preamplifier Approximately 140 ft

Method of grounding A single-point grounding system is used System ground is made at the amplifier cabinet The signal cable and neutron detector are insulated and floated above ground The two shields in the triaxial cable are connected together to one electrode of the neutron detector The two shields are grounded at the amplifier cabinet The signal ground in the preamplifier and the amplifier are grounded at the amplifier cabinet The amplifier cabinet is grounded to the building ground through grounding cable and buses
