在给定长度和介电常数的同轴脉冲形成线（PFL）中，使用改进的螺旋技术使脉冲长度增加了一倍。改进后的螺旋由大量绝缘电缆组成的圆柱体组成，这些电缆首先与PFL轴平行敷设，然后给予适度的扭转。PFL本质上是一种螺旋延迟线，其形式实现了大量的脉冲拉伸，而不会引入显著的匝间电压梯度或脉冲形状的畸变。该技术可用于增加固定阻抗和脉冲持续时间的PFL单位长度存储的能量
The pulse length available from a coaxial PFL (pulse-forming line) of given length and dielectric constant has been doubled using a modified spiral technique. The modified spiral consists of a cylinder formed from a large number of insulated cables which are first laid parallel to the PFL axis and then given a moderate twist. The PFL is essentially a helical delay line in a form which accomplishes substantial pulse stretching without introducing significant turn-to-turn voltage gradients or distortion of the pulse shape. The technique can be used to increase the energy stored per unit length for a PFL of fixed impedance and pulse duration.>
