自金属——陶瓷结构的行波管闻世以来,其慢波结构的夹持方法普遍采用的是变形夹持。在功率小、频率低、尺寸大的情况下,它能充分发挥其操作简便、快速而且具有一定散热能力的优点,但随着电子科学技术的发展,对行波管的要求也愈来愈高,目前已发展到毫米波及亚毫米波。不但要求管子尺寸小,还要有较大的输出功率。因而整管的散热问题就限制了行波管的发展。同时,变形夹持的缺点就明 Since the traveling wave tube of the metal-ceramic structure has been widely used in the world, the sandwiching method of the slow-wave structure is widely used. Under the conditions of small power, low frequency and large size, it can give full play to its advantages of easy operation, fast and certain heat dissipation capacity. However, with the development of electronic science and technology, the requirements for traveling wave tube are also getting higher and higher , Has now developed to millimeter and submillimeter waves. Not only requires the tube size is small, but also have a larger output power. Therefore, the issue of cooling the entire pipe to limit the development of traveling wave tube. At the same time, the shortcomings of the deformation grip on the clear
