The exit window of the second polarizer. The polarizers are placed in a concrete casemate and
shielded with lead to reduce the gamma background.

The vacuum system starts right behind the polarizers. Here one can see the radiofrequency spinflipper
which is used to turn the neutron spins by 180 degrees.

Perkeo II installed at the beam place PF1B. It is placed inside a steel shielding to reduce the
magnetic field outside the experiment. The neutrons fly from the front to the back of the photo.

The electron spectrometer Perkeo II installed inside the steel shielding. In the front one
can see the part of the vacuum vessel, where the detector and the photomultipliers are
placed.
