Image of the glass shell made by applying a pinhole chamber.
This reference wave is generated by the diffraction of a very small pinhole.
Therefore, this image may be observed for the maximum diaphragm by the pinhole camera only.
Quasi-monoenergetic electron beam generation by using a pinhole like collimator in a self-modulated laser wakefield acceleration.
The empty square and the full circle indicate the transmission through a 100 mm pinhole and a 40 mm pinhole respectively.
Thus, an increased signal at the detector additionally would allow one to reduce the entrance pinhole diameter of the spectrometer.
Two pinhole cameras were fielded to record the time-integrated image of the pinch.
The distance from the pinhole disk to the photocathode was 1115 mm.
