“…The problem of increasing the amount of the collected ionization products to be measured is solved in a different way in two-dimensional monitors described in [21,22]. The path of the beam in the monitor along which the ionization products are collected for measurements has been increased by about two orders of magnitude by changing the structure and incorporating the scanning process.…”

An IPM monitor to measure a detailed profile of the beam has been developed and constructed. The monitor was developed in the course of modernization of the structure operating on the basis of electric field scanning. The monitor also consists of an extractor, a scanner and two electrostatic analyzers in series. A system to control the monitor and process the data has been developed and produced. As a result of performance testing of the monitor it is established that it allows detailed measurements of the profiles of wide beams with a resolution of 1.5х1.5 mm2. It is found that the monitor minimum sensitivity is n‧103 particle/cm2‧s for the 132Хе26+ ion beam with the energy 1.2 MeV/nucleon and the pressure 5 10-4 Pa of permanent gas in the diagnostic unit. The monitor fits for control of both creation of a uniform distribution of the beam profile and continuous observation of uniformity variations during exposition. The detail profile monitors have been developed for the 45 mm diameter beam for a setup to conduct studies in the field of radiobiology and for the 60mm diameter beam for investigation of radiation effects of radioelectronic equipment.

The design and the performance of the primary beam diagnostic system operating on a non-intercepting measurement method are described. It was assembled for operation under harsh environmental conditions. The main part of the beam detection system is the Ionization Beam Profile Monitor (IBPM) operating on the ionization of the residual gas principle. The primary beam diagnostic system provides data sufficient to plot spatial distributions of the beam current in the monitored area operating in on-line regime. It was used to monitor the profiles of 7 Li, 11 B, 32 S beams in the energy range of 30 50 AMeV and 20 Ne, 40 Ar, 86 Kr, 132 Xe beams at 4 5 AMeV. All measurements were performed under the conditions of high gamma and neutron flux. The diagnostic box was located in the vicinity of the accelerator, where the neutron flux was over 10 6 neutrons cm 2 s. The beam current was in the range of a few nA up to 15 A. The device operates in vacuum on the level of 10 6 10 3 mbar without loss of resolution power at the beam current as low as a few nA. Long operation time and emergency situations do not lead to decrease of its operability.Index Terms-Hard radiation conditions, heavy ion beams, ionization beam profile monitor, on-line beam monitoring, the U400M cyclotron of FLNR JINR.

“…Under our experimental condition we cannot use such electrode because of insufficient amplitudes of collected signals. We have chosen ionization monitor described in [9] with collector which gain ions from only a narrow fraction of scanned volume. Whole volume is analyzed by application of scanning potential.…”
