来自新的波粒子相关器的观测显示了由单色朗缪尔波电场引起的电子相位聚束的明确证据，该电场的振幅变化缓慢。发现电子相对于波场成90°聚束，表明它们是扰动分布函数的反应分量。这与预测电子通过非常长的波场的这种相位关系的理论是一致的。
Observations from a new wave‐particle correlator show clear evidence of phase bunching of the electrons by a monochromatic Langmuir wave electric field which varied slowly in amplitude. The electrons are found to be bunched at 90° with respect to the wave field indicating that they are the reactive component of the perturbed distribution function. This is in agreement with theory that predicts this phase relation for the transit of electrons through a very long wave field.
