Estimation of Dense Plasma Temperature Formed under Shock Wave Cumulation

Area of Science:

• Plasma Physics
• Nuclear Physics
• Materials Science

Background:

• Super dense plasma jets are generated using implosion plasma generators.
• Understanding the boundary temperature and pressure of these jets is crucial for assessing their impact on materials.

Purpose of the Study:

• To quantitatively assess the boundary temperature of super dense plasma jets.
• To investigate nuclear transformations in metals induced by these jets.
• To explore the conditions for elemental formation and material structural changes.

Main Methods:

• Utilizing implosion plasma generators with conical and hemispherical compression chambers.
• Conducting quantitative assessments of super dense plasma jet boundary temperatures.
• Analyzing elemental composition changes in metal targets post-plasma jet impact.

Main Results:

• Experimental proof that nuclear transformations in metals are caused by super dense plasma jets (11–12 × 10³ kg/m³).
• Estimated nominal boundary temperature of plasma generators at 10⁶ K.
• Formation of stable manganese isotopes (Mn⁵⁵, up to 27%) in iron targets, linked to iron isotope transformation (Fe⁵⁶, Fe⁵⁴).
• High pressures (>30 TPa) generated upon jet penetration at 28,000 m/s.
• Boundary temperature showed slight dependence on pre-determined values.

Conclusions:

• Super dense plasma jets induce significant nuclear transformations in metals.
• The study provides a method for investigating material changes under extreme conditions.
• The findings contribute to understanding the physical conditions of chemical element formation.
