Archived - Magnetic field + fusor grid

Post by kcdodd »

Part of a side project using fusor grids with a magnetic field. A local HS student will be expanding this with their own grids. This grid I made just to see what would happen.

Picture 1: Setup

Red are magnetic coils.

Internal camera views are from the lower port with a webcam and aluminum foil cover.

Picture 2: DC Discharge (no field)

air fill. pressure was around 10 mTorr. Voltage is a few kV.

Picture 3: DC Discharge (with field)

Same parameters with the addition of a spindle-cusp magnetic field, with maximum value of about 500 Gauss.

Great setup you have there! It's clean, neat and safe! What's the voltage and power required for a 500 gauss magnet ?

Well, this is with just 2 of the 4 coils shown in the 1st picture. Each one has 100 turns. One car battery runs them in series: ~10V at ~250A, or 2.5kW. No water cooling at all. Also keep in mind that 500 gauss is only in the cusp regions. At the center where the grid is, the field goes to zero. Eventually the plan is get to 4kG.

Carter,

Impressive rig!

Since we only know of two fields that influence the path of charged particles, it makes sense that we should utilise both in an ion confinement device.
