    • A microwave absorber composed of dense silicon carbide having an electrical resistivity of one ohm-centimeter or more. In an electron linear accelerator, it is necessary to provide a microwave absorber to absorb excess energy used to accelerate electrons and discharge this excess energy in the form of heat in order for the accelerator to operate safely. The important characteristics are high-frequency wave absorption, good heat resistance, good thermal conductivity, and stability in a vacuum. The invention meets these requirements with a microwave absorber composed of dense silicon carbide. In an electron linear accelerator the absorber is attached to the end portion of an accelerator guide or a branch portion of a power divider to absorb unnecessary wave energy. Such a microwave absorber is found to have characteristics rendering it highly suitable for this application as well as others.
    • 由具有1欧姆厘米或更大的电阻率的致密碳化硅构成的微波吸收体。 在电子线性加速器中,需要提供一种微波吸收器,以吸收用于加速电子的过量能量,并且以热的形式排放多余的能量,以使加速器安全地运行。 重要的特点是高频吸波,耐热性好,导热性好,真空稳定性好。 本发明利用由致密碳化硅组成的微波吸收器来满足这些要求。 在电子线性加速器中,吸收器附着到加速器引导件的端部或功率分配器的分支部分以吸收不必要的波能量。 发现这种微波吸收器具有使其非常适合于该应用以及其它应用的特征。
