چکیده

در این مقاله یک ساختار کندموج موجبری جدید به صورت شش پرتوی با هدف افزایش توان در لامپ‌های موج رونده پیشنهاد شده است. لامپ های موج رونده به پهنای باند زیاد و توان خروجی کم نسبت به دیگر لامپ‌ها معروف هستند و از ساختارهای کندموج به منظور برهم‌کنش بین موج الکترومغناطیسی و پرتوی‌ الکترونی استفاده می‌کنند. ساختار کندموج پیشنهادی به دلیل چندپرتوی بودن و داشتن مود اصلی رو به جلو ، در مقایسه با ساختارهای کندموج معمول، توان خروجی بیشتری دارد و می‌تواند در باند X با شش پرتوی الکترونی 62 کیلوولت و 23 آمپری به بهره 35 دسی بل، توان خروجی 2.15 مگاوات، پهنای باند 1.2 گیگاهرتز و بازدهی 25 درصد برسد.

چکیده [English]

In this paper, a navel slow wave structure (SWS) with six beam is presented for increasing the power of Traveling wave tubes (TWT). In comparison with other tubes, TWTs are characterized by a high bandwidth and a low output power and utilizing SWSs for the interaction of electromagnetic Waves and electron beams. The proposed structure has more output power due to its multibeam and fundamental forward mode compared to other structures, and with six electron beams of 62KV and 23A, it can achieve a gain of 35dB, an output power of 2.15MW, a bandwidth of 1.2GHz, as well as a 25% efficiency in the X band.
