Nuclear Fusor

Learn how this ambitious project was possible at Cardiff Sixth Form College, Cambridge.

General Information

The Inertial Electrostatic Confinement Fusor (IECF) is a device capable of achieving fusion at a domestic level without requiring a multi-million-pound reactor.

It uses electric fields around a negatively charged inner grid to accelerate ions, reach fusion conditions, and confine the plasma inside a vacuum. Deuterium (and Tritium, if possible), which are hydrogen isotopes 2H and 3H, respectively, act as the fuel of the fusion reaction by being introduced into the chamber.

This process is also possible due to the properties of quantum principles, particularly quantum tunnelling, which means not all particles require high amounts of energy to collide and fuse.

About our reactor

At this stage, the CSFC Cambridge Fusor is still incapable of producing neutrons due to some complications with the received equipment. It can, however, form a plasma around the inner grid (cathode).

The reactor is currently equipped with:

– A rotary vein vacuum pump which allows the pressure to drop to about 10e-3 Torr
– A needle valve for fine control of the chamber’s pressure
– A repurposed 5.000 volts power supply for electron diffraction (it was designed to be used in schools and limited to 2 mA, making it very safe)

Additionally, to ensure maximum safety, a Raspberry Pi and 2 Arduino Uno will be installed and used to control the reactor remotely from another room through a Python-based Interface. This system will instruct stepper motors and collect data for the user, which can be saved and analyzed.
