氦基混合气体被用来降低多重散射对中能粒子动量分辨的贡献。计算了几种混合气体的相关输运参数，即漂移速度和扩散，并与标准的氩基混合气体进行了比较。已经确定了一些快速、低扩散的混合物。计算的小洛伦兹角使它们成为在磁场中进行漂移室操作的有希望的候选者。
Helium based gas mixtures have been investigated for lowering multiple scattering contributions to the momentum resolution for intermediate energy particles. The relevant transport parameters, namely drift velocity and diffusion have been calculated for several mixtures and compared to standard argon based mixtures. Some fast, low diffusion mixtures have been identified. The small Lorentz angle computed make them promising candidates for drift chamber operation in magnetic fields.
