I work on a plasma confinement device that has a linear regulator in its 100 kV gyrotron power supply that uses 6 kW just to keep the filament warm. The coils use 10 MW during a shot. And this is considered a small machine.
Science takes power.

- willis936 5y agoWell the pay is about half the market rate and I'm leaving soon because my SO's research group is moving across the country. I suppose I'll just go work for industry and be able to pay off student loans/own a house in my life. Science could hold on to talent if only there was a budget for it.
- idiotsecant 5y agoNeat! How long does it take to charge capacitors before a shot? Or do you have a transmission feeder directly into your lab?
- willis936 5y agoWe use 18 DC train motors with 1-ton flywheels on them. Currently they spin up to 1650 RPM then get turned into generators. It takes about a second to spin up the very inductive copper coils to the desired current then the shot lasts 100 ms. After the shot the motors are spinning at 1200 RPM and it takes 5 minutes to get back up to 1650 RPM.
