Vibrating Wire Station for Horizontal and Vertical Profiling of Proton Beam of Cyclotron C18 in Air

The paper presents the results of the first experiments on measuring the horizontal and vertical profiles of the proton beam of the C18 cyclotron using a profiling station based on vibrating wire monitors. The measurements were performed at the proton beam exit into the air from a special vacuum window located at the end of the cyclotron beam guide. The profiles were measured for different values of proton beam current. The station showed its operability under the conditions of strong disturbances caused by the exposure of protective lead plates to the proton beam.
