Example concept:
Instead of a solid projectile, the launcher accelerates plasma.
How It Works
A Plasma Railgun still uses two electrodes like a normal railgun, but the armature is replaced with ionized gas (plasma).
Steps:
1. gas becomes ionized into plasma
2. current flows through plasma between rails
3. electromagnetic forces accelerate the plasma forward
This produces a jet of extremely fast plasma.
⸻
Uses
These devices are usually not weapons.
They are used in:
• plasma physics research
• fusion experiments
• high-energy density physics
• spacecraft propulsion studies
Some plasma railguns can accelerate plasma to tens or hundreds of km/s in laboratory experiments.
⸻
Typical Sizes
Research devices:
• 0.5–2 meters long

A Helical Railgun is essentially a hybrid between a railgun and a coilgun.
How It Works
Instead of straight rails alone, the system includes a helical electromagnetic winding around the rails.
Current path:
1. current flows through rails
2. sliding electrical contacts on the projectile activate the helical winding
3. the winding creates additional magnetic acceleration
This means the projectile interacts with both:
• rail current
• magnetic coils
This can reduce the extreme current required by normal railguns.
Historical Prototype
One early experimental system at MIT:
• about 3 meters long
• powered by large capacitor banks
• launched small gliders in experiments.
⸻
Advantages
• lower current requirement
• potentially more efficient
Disadvantages
• complex electrical contacts
• still experimental

Coilgun (Gauss Gun)
A Coilgun is the most well-known electromagnetic launcher alternative.
How It Works
Instead of rails, a coilgun uses a sequence of electromagnets (coils).
When powered sequentially:
1. first coil pulls projectile forward
2. next coil activates as projectile passes
3. magnetic field continues pulling it down the barrel
The projectile never touches the barrel, which reduces wear.
⸻
System Components
• magnetic coils along barrel
• timed switching electronics
• ferromagnetic projectile
• energy storage (capacitors or batteries)
Each coil turns on briefly to pull the projectile forward.
⸻
Typical Sizes
Hobby / experimental
• 20–60 cm long
Laboratory
• 1–3 meters long
Research launchers
• multi-stage accelerators several meters long
⸻
Advantages
• less mechanical wear
• easier to miniaturize
• quieter operation
Disadvantages
• lower efficiency than railguns
• complex timing electronics required
