By the time the ship reaches ramscoop speed the fuel is half gone, replaced by low-pressure gas.

They work on the principle that passing a high voltage through a low-pressure gas generates light.

The thyratron is a special-purpose tube filled with low-pressure gas or mercury vapor.

The low-pressure warm gas is cooled in an ambient cooler.

The low-pressure cold gas is compressed to the high-pressure of the system.

A glow discharge is a plasma formed by the passage of electric current through a low-pressure gas.

An all-glass tube with any low-pressure gas sealed inside would glow too.

The low-pressure gas, referred to as the driven gas, is subjected to the shock wave.

Glow discharge plasma is created by filling a vacuum with a low-pressure gas (ex.

Once launched, it unrolls and inflates in space into a long sausage-skin full of low-pressure gas.
