## What is Ampere?

Explore plasma physics through interactive simulations and transparent educational calculators.

SIMULATE PLASMA PHENOMENA
• Guide animated plasma-globe filaments
• Explore a Paschen-law glow-discharge model
• Drive a 13.56 MHz RF reactor solved by a global discharge model
• Adjust an illustrative tokamak control visualization

CALCULATE CORE PARAMETERS
• Debye shielding length
• Electron plasma frequency
• Paschen breakdown voltage
• Synthetic planar Langmuir-probe response
• Lossless 13.56 MHz RF L-network matching
• Bohdansky physical sputter-yield estimates

Ampere works offline and requires no account or purchase. Every advanced model states its assumptions and limitations. Results are intended for education and first-pass exploration, not professional engineering or safety decisions.


## Version history (last 2 releases)

### 1.1.0 — 2026-07-31

New in 1.1.0: the RF Plasma Reactor — a 13.56 MHz capacitively-coupled argon chamber solved by a volume-averaged global model. Set absorbed power, RF voltage, and pressure to see electron temperature, density, ion flux to the wafer, ion bombardment energy, and Child-law sheath width, with every assumption stated on screen.

### 0.0.1 — 2014-09-12

No release notes.
