Investigation of a Planar Langmuir Probe Orientated Parallel to the direct of Flow in a Laser Ablation Plasma

摘要: Langmuir probes are a well established tool for investigating the characteristics of laser produced plasmas. Such plasmas typically take form highly directed plumes, with flow velocities that supersonic respect to ion sound speed. The behaviour planar in such conditions dependant on both plasma parameters and orientation probe flow. theory flowing is not developed. This limits their usefulness as diagnostic tools various applications where encountered. adaptations made associated [1,2] implantation (PIII) describe I-V discussed. resultant analytical when used combination one dimensional particle cell simulations shown provide an excellent description at early times.
