Zusammenfassung:	A pulsed neutron well logging system is disclosed having a novel ion source control system providing extremely sharply time defined neutron pulses. A low voltage input control pulse is utilized to produce a relatively sharp rising high voltage ion source control pulse. Simultaneously a delayed quenching circuit control pulse is produced to rapidly quench the high voltage ion source control pulse after a predictable time delay from its onset. The resultant ion source control voltage (and hence neutron output) is sharply defined timewise.
