Abstract :
An automatic Hall-type magnetometer for magnetic measurements of focusing channel elements with arbitrary field configuration is described. The Hall probe housing supported around the periphery provides 3D precise movement in 75% of aperture space. The measurement technique and mathematical treatment developed to create the spatial model of the field are given. The magnetometer ensures the accuracy 0.3% of the maximum field value in a whole magnet working space. Measurement runs for quadrupole lenses of the ISTRA linac focusing channel are presented
