摘要:
This paper presents the results of the development and implementation of fast wire scanners based on servomotors with a resolver and standard control electronics at a speed of 16 m/s at the U-70 IHEP accelerator. Profilometers are designed to measure the density distribution of proton and carbon beams in the horizontal and vertical planes. The motors of scanners are controlled by servocontrollers through the Copley Motion Explorer CME2 software shell. The beam profile is recorded using scintillation detectors. The beam profile and dimensions were processed using a program developed in the LabVIEW environment. To determine the beam revolution frequency, the fast Fourier transform and the integration of the measured input signal over a given number of beam revolutions are used. The beam parameters are given for a wide range of particle intensities and energies.
