Abstract
ONE COMMON NUCLEAR WEAPONS EFFECTS CIMULATION TECHNIQUE SIMULATES THE EMP RESPONSE OF LONG CABLES USING DIRECT CURRENT INJECTION. DIRECT CURRENT INJECTION TYPICALLY INVOLVES THE CONNECTION OF HIGH VOLTAGE PULSE SOURCES TO THE CABLES THAT ARE ATTACHED TO A MILITARY SYSTEM. A RECENTLY DEVELOPED MILITARY STANDARD SPECIFIES THAT DIRECT CURRENT INJECTION TESTING WILL BE USED IN CONJUNCTION WITH SEVERAL OTHER TEST TECHNIQUES IN THE ACCEPTANCE AND HARDNESS VERIFICATION TESTING PROCESS. NEW PULSE SOURCES DESIGNED TO MEET THE TEST REQUIREMENTS OF THE NEW STANDARD MUST BE DIRECTLY CONNECTED TO THE PENETRATION UNDER TEST. THE NEED EXISTS FOR A SIMPLE, NON-CONDUCTIVE METHOD OF CONNECTING HIGH LEVEL PULSE SOURCES TO PENETRATIONS UNDER TEST. DESIRABLE CHARACTERISTICS FOR THE COUPLER INCLUDE LOW COST, COMPATIBILITY WITH EXISTING PULSERS AND SMALL VOLUME AND WEIGHT. THE OVERALL PROGRAM OBJECTIVE IS TO DEVELOP AND DEMONSTRATE AN INDUCTIVE COUPLING TECHNIQUE FOR USE THE PULSE CURRENT INJECTION SOURCES. THE INDUCTIVE COUPLER WILL AID IN THE SIMULATION OF THREAT LEVEL EMP EFFECTS ON SYSTEM PENETRATIONS SUCH AS AC POWER LINES AND LONG LINE COMMUNICATION CABLES. THE PROPOSED EFFORT WILL APPLY RECENT ADVANCES IN INDUCTIVELY COUPLED CABLE DRIVER WORK TO THE DEVELOPMENT OF AN INDUCTIVE COUPLER THAT WILL INTERFACE WITH DIRECT DRIVE PULSERS. THE INDUCTIVE COUPLER WILL BE CONNECTED TO THE HIGH VOLTAGE SOURCE AND WILL CLAMP AROUND THE CABLE UNDER TEST.
