摘要
Techniques for monitoring a pulsed neutron source include measuring a burst count rate while the pulsed neutron source is turned on using a monitor detector disposed proximate the pulsed neutron source; measuring a decay count rate while the neutron source is turned off using the monitor detector; and deriving a source strength indicator from the burst count rate and the decay count rate. A pulsed neutron tool includes a tool body; a pulsed neutron source disposed in the tool body; a monitor detector disposed in the tool body proximate the pulsed neutron source; at least one measurement detector disposed in the tool body at a predetermined distance from the pulsed neutron source; and circuitry disposed in the tool body for controlling the pulsed neutron source, the monitor detector, and the at least one measurement detector.
