Abstract:

DMS (DILUTED MAGNETIC SEMICONDUCTOR) CRYSTAL WILL MEASURE MAGNETIC FIELD STRENGTHS OF A HYPERVELOCITY GUN (HVG), WITH UNIQUELY HIGH DIRECTIVITY AND SPATIAL RESOLUTION, UNDER A HARSH ELECTRO-MAGNETIC INTERFERENCE (EMI) CONDITION. KNOWLEDGE OF THE MAGNETIC FIELD STRUCTURE BEHIND AND AHEAD OF A PROJECTILE IS ESSENTIAL FOR DESIGNING AN EFFICIENT HVG OF SDI INTEREST, ALTHOUGH EMI MAKES SUCH A MEASUREMENT OFTEN UNRELIABLE WITH CONVENTIONAL MAGNETIC PICKUP PROBES. A NOVEL M-O CRYSTAL WAS USED FOR SOLVING THE PROBLEMS. THE EMI WOULD NOT INCREASE THE FREQUENCY DUE TO THE FLAT RESPONSE TO GHZ. THE DIRECTIVITY AND SPATIAL RESOLUTION IS AS GOOD AS THOSE OF PROBING LASER BEAM. THE PHASE I REPORT HAS PRESENTED PHYSICS OF THE GIANT FARADAY EFFECT OF DMS AND EXPERIMENTAL VERIFICATIONS/DEMONSTRATION OF THE BASIC M-O EFFECTS, LINEARITY AGAINST DC FIELD STRENGTHS, VERDET CONSTANT 580 TIMES GREATER THAN QUARTZ FOR A CD(1-X)MN(X)TE, X=0.45 SMPLE, HIGH FREQUENCY RESPONSE, SIMPLE POLARIMETER BASED ON THE INTENSITY METHOD, AND SENSOR SYSTEM WITH A 6.75KJ HVG.
