    "abstract": "The Laser-wire will be an essential diagnostic tool at the International\nLinear Collider. It uses a finely focussed laser beam to measure the transverse\nprofile of electron bunches by detecting the Compton-scattered photons (or\ndegraded electrons) downstream of where the laser beam intersects the electron\nbeam. Such a system has been installed at the PETRA storage ring at DESY, which\nuses a piezo-driven mirror to scan the laser-light across the electron beam.\nLat- est results of experimental data taking are presented and compared to\ndetailed simulations using the Geant4 based program BDSIM.",
