Abstract
IH (Interdigital H-type) and SPR (split ring) structures are used to accelerate ions at low energies and relatively low operating frequencies. A procedure for selecting the parameters of drift tubes (DTs) is proposed to achieve high HF efficiency and simultaneously suppress the dipole parasitic component of electric fields at a given electrical strength. A database of DT variants based on six free geometric parameters is compiled using modern software in an electrostatic 3D approximation. The final variant is selected through sequential interpolation of the database. Fourier coefficients of the expansion of the accelerating field on its axis are also derived to calculate the particle dynamics in the selected DT variants.
IH （Interdigital H-type）和SPR （split ring）结构用于在低能量和相对低的工作频率下加速离子。提出了一种选择漂移管（DTs）参数的方法，以获得较高的高频效率，同时抑制给定电强度下电场的偶极子寄生分量。在静电三维近似下，利用现代软件编制了基于六个自由几何参数的DT变异体数据库。通过对数据库的顺序插值选择最终的变量。推导了加速场在其轴上展开的傅里叶系数，以计算所选DT变体中的粒子动力学。
