Success! Switch Tests End, LPP Fusion's FF-2B to Fire in January

• arclein

In November, we demonstrated that the new dual switches could pass a greater current than the single switches. However, the greater current turned out to be too much for our spare test capacitor, which failed. Fortunately, we were able to locate a smaller, used but suitable capacitor within days and got back to testing after only a few weeks down. We upgraded our test bed to include coils of wire acting as a resistor. These coils limit the current and harmlessly dissipate energy (see Fig.1). We also attached old plasma focus electrodes into the circuit and pumped the vacuum chamber down to better simulate the actual firing conditions of the FF-2B device.
