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

What They Are
Microwave weapons emit high-energy radio frequency pulses that disrupt or destroy electronics.
Instead of physical damage, they attack:
• circuits

• navigation systems
These systems are often called High Power Microwave (HPM) weapons.

How They Work (Concept)
The weapon produces a powerful electromagnetic pulse.
When the pulse hits electronics:
1. energy enters antennas, wires, and circuits

3. components overload or fail
This can:
• temporarily disrupt electronics
• permanently damage circuits

1. Power Supply
• High-voltage source: Both coilguns and plasma devices need a source of extremely high voltage. This could be a compact battery combined with a DC-DC boost converter to raise the voltage to tens or hundreds of kilovolts.
• Energy storage: Because batteries can’t deliver such sudden power directly, energy is typically stored in capacitor banks. Capacitors can release large currents almost instantaneously, which is critical for accelerating projectiles or generating plasma.
⸻
2. Switching Systems
• High-speed switches: To release stored energy from capacitors at the right moment, you need switches capable of handling very high currents and voltages.
Examples include:
• Solid-state switches (like IGBTs or MOSFETs, sometimes in series/parallel arrays)
• Spark gaps (for extremely high voltage pulses, older tech, but conceptually relevant)
• Trigger circuits: These detect when to fire and activate the switches with microsecond or even nanosecond precision.
⸻
3. Control Electronics
• Timing circuits: For a coilgun, multiple coils need to fire in sequence as the projectile moves. This requires:
• Microcontrollers or FPGAs for precise timing
• Position sensors (optical, magnetic, or Hall-effect) to track the projectile’s speed and location
• Pulse shaping: Electronics often shape the current pulse to optimize acceleration. This can involve RC or LC circuits to control rise/fall times.
⸻
4. Magnetic/Electromagnetic Systems
• Coil drivers: In a coilgun, each coil is an inductor that must be energized with a precisely-timed current pulse. The driver electronics handle:
• Delivering high current quickly
• Controlling pulse duration
• Ensuring coils don’t back-feed current (which could damage circuits)
• Plasma generation: Plasma rifles need high voltage across a gap to ionize gas. That requires:
• High-voltage pulse circuits
• Possibly resonant LC circuits to maximize energy transfer into the plasma arc
⸻
5. Safety and Feedback
• Overcurrent/overvoltage protection: To prevent catastrophic failure of the electronics.
• Thermal management: High currents generate heat; electronics often include sensors and active cooling systems.
• Feedback loops: Especially in experimental systems, to monitor capacitor voltage, coil current, and firing success.
⸻
6. Optional Advanced Systems
• Pulse-forming networks (PFNs): Used to tailor the energy waveform to improve efficiency.
• Supercapacitors or ultracapacitors: For repeated rapid fire without waiting for batteries to recharge.
• Magnetic energy recovery circuits: To reclaim some of the energy left in coils after a shot.

At a high level, a handheld “electrical weapon” needs three core subsystems:
1. Energy storage and delivery → capacitors, batteries, high-voltage DC-DC converters
2. Switching and timing control → MOSFETs/IGBTs, triggers, sensors, microcontrollers/FPGAs
3. Electromagnetic conversion → coils or electrodes with pulse-shaping, feedback, and safety circuits
Everything else; cooling, safety interlocks, efficiency tweaks
