    Abstract

    For measuring the laser beam profile a vibrating wire monitor (VWM) was used. The measurements were carried out at different speeds of scanning. Preliminary estimates for calculation of the VWM response times with respect to the thermal losses along the wire, radiative and convective losses, were made. These estimates, however, do not determine the measure of the difference between the beam profile and the frequency response of the VWM for a given scanning rate. To evaluate the measure of the reliability of the frequency response of the VWM, the comparison between forward and reverse beam scans at different speeds is used. The results of these scans are used to correct the thermal inertia in the frequency response of the VWM.
