We use the way of cut - and - try. it involves a sequence of experiments to determine the matching and tuning. the effort can be time - consuming and requires substantial expertise empirical expertise. so it is important to find some new ways to design coupler cavity
以前，耦合腔的尺寸確定過程相當復雜，基本是按如下過程實現：通過以往經驗先做出實驗腔，進行測試，發現問題，再修正腔，再進行測試。這就很費時、費力、費錢。 -
As far as input coupling devices concerned, we design a feasible taper coupler by means of the theory of waveguide coupling and outside cavity waveguide laser and make decision of the sizes of the lens and the taper coupler, and the relative distance of them. the focus of the lens is 65mm and the radius is 5mm. the length of the taper coupler is 15mm, and the radiuses of the input and output ends separately are 17mm and 0. 65mm
在輸入耦合器方面，藉助于波導耦合和外腔式波導激光器的相關理論，設計了工藝上可行的錐型耦合器，確定了透鏡、耦合器的尺寸以及耦合器與透鏡的相對位置：耦合透鏡的焦距為65mm ，直徑為srnm ，耦合器的長度為15mm ，輸入端直徑為17mm ，輸出端直徑為0 -
The couplers of accelerator structures are important components of electron knear. the efficient delivery of power from rf sources to accelerator structures depends crucially on the coupler cavity. the input coupler cavity is to be well matched, that is to say, it must have proper coupiing. and it must be tuned to the synchronous frequency. in this way, we can obtain the maximum power. in the past, the decision of the coupler cavity dimensions is very difficult
