固定场交变梯度（FFAG）加速器最近受到强烈的复兴。它们通常被设计成圆形;然而，在这种类型的加速器中，引导粒子而没有整体弯曲将是一种资产。本文介绍了一种保持零色度的直式FFAG池的分析研制。由此得到了一个磁场定律，称为“直标度定律”，并进行了实验验证。设计并制造了直标度FFAG原型，测量了两种不同能量的水平相位提前量。结果进行了分析，澄清直接标度律。
Fixed field alternating gradient (FFAG) accelerators are recently subject to a strong revival. They are usually designed in a circular shape; however, it would be an asset to guide particles with no overall bend in this type of accelerator. An analytical development of a straight FFAG cell which keeps zero-chromaticity is presented here. A magnetic field law is thus obtained, called “straight scaling law”, and an experiment has been conducted to confirm this zero-chromatic law. A straight scaling FFAG prototype has been designed and manufactured, and horizontal phase advances of two different energies are measured. Results are analyzed to clarify the straight scaling law.
