It says "In order to obviate..." on page 3 where it explains that function in a short text. Here's another explanation of the use https://www.kimballphysics.com/PDFs/general_options_pulsing_blanking.pdf. You can leave the beam turned on, not turned off by the grid or by other means, and have it locked (trapped) onto the beam trap so that it won't illuminate the screen, it is usually easier to see a single fast pulse on the screen then as the screen is not illuminated by the beam after the pulse has been displayed. Here's a patent discussing the beam trap: https://www.google.com/patents/US3867668
