Popis:	A theory describing the ac space charge effects in plasma-filled traveling-wave tubes (TWT) is presented. It is shown that in the case of operation at frequencies between the plasma frequency and the upper-hybrid frequency, the space charge forces can significantly enhance the efficiency. The analysis of a concrete, plasma-filled, coupled-cavity TWT shows that over a 20% bandwidth the calculated efficiency can exceed 40%.
