WHAT IS FUSION?
Fusion occurs when two nuclei combine to from a new nucleus
Fusion fuels are mainly Deuterium and Tritium
Deuterium
Tritium
Has one proton and two neutrons
Deuterium-Tritium Fusion
Plasma
Plasma is made up of atoms
it is also called ionized gas
CONDITIONS SHOULD BE CREATED FOR THE FUSION TO OCCUR
The two nuclei should be bring in contact
High temperature
About 100 million °C
Created by using Laser beams,
microwaves
High pressure
Pressure squeezes the hydrogen atoms together
Using intense magnetic fields, powerful lasers or ion beams
MANETIC CONFINEMENT FUSION PROPULSION
Magnetic Confinement Fusion (MCF)
Electricity & neutral particle beams are used to heat the stream of gas
Plasma is squeezed by the super conducting magnets
Fusion occurs
Products exhausted through a magnetic
nozzle
Inertial Confinement Fusion (ICF)
Uses laser beam or ion beams to heat & squeeze the hydrogen plasma
Heating and compressing a target – a pellet that most often contains deuterium and tritium – by the use of intense laser or ion beams
Beams detonates the outer layer
Sending a shock wave in to the center if it is powerful then heated to cause fusion
MUON-CATALYSED FUSION PROPULSION
Eliminates electric repulsion force & fusion take place
Fusion energy ejects the muon& goes of to another nucleus
Catalyses many reactions
CONCLUSION
This concept increases the mission flexibility, enabling new science missions and greater flexibility in reaching & exploring distant
It reduces the time for the journey in space mission by 50% compared to the chemical rocket
