Abstract:
The transverse beam profile at the PETRA positron storage ring will be
measured using a two-dimensional laser-based beam profile monitor. Such a
device, newly installed, uses a finely focused laser beam to scan across the
charged particle beam. The flux of the compton scattered photon varies with
the position of the laser beam, thus establishing the transverse beam
profile. In this paper, aspects related to the laserwire setup, such as the
focusing optics, both pre-and post-interaction point diagnostics optics,
scanning optics, and ghost analysis are described in detail.
