Abstract
A coupled-cavity delay line for traveling-wave tubes is provided with a cooling system which permits heat distribution along the entire length of the delay line and ensures that the outer surface of the vacuum enclosure is isothermal. The cooling system consists of a cylindrical sleeve containing heat pipes. The cylindrical sleeve is located between the external wall of the resonant cavities and the permanent magnets. The heat pipes are disposed at uniform angular intervals within the double-walled sleeve and extend lengthwise along the delay line.
