“…The following conclusion can be drawn from the linear equation (1): the beam distribution can be measured simultaneously in two mutually perpendicular directions. To accomplish this, it is necessary to determine the sign of the coefficient of the variable in (1) and, in the simplest case (for which ), to transform (1) to the form: (2) If this condition is met, the slope coefficient of the straight line is equal to unity.…”

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.

“…The first use of IPMs dates back to the 1960s [4]. In the 90s, the raise of the MicroChannel Plates have permitted to measure profiles [5], [6] in more critical working conditions. The IPM method is now mature and used in several installations [7]- [10].…”

Saclay CEA/IRFU is working for the delivery of five Non-Invasive Profile Monitors in the frame of the in-kind contribution agreement signed with the European Spallation Source. Neutrons will be produced by spallation reactions of 2 GeV proton beam impinging on a Tungsten target. To accelerate protons a powerful linear accelerator of 5MW is under construction. Diagnostic devices are mandatory tools for the tuning and protection of the machine. The non-invasive profile monitors provide a measurement of the beam profile in transverse directions to the beam propagation. This project raises several physical and technical challenges including low signal detection of ions or electrons, profile distortions induced by the beam Space Charge effect and non-uniformities of electric field. Simulation and model of the critical aspects of the detector have been performed in order to prove the performance and the feasibility of the detector. A series of prototypes has been built with different readout types, and tested in real conditions at the 3MeV proton accelerator IPHI. All of them show some advantages and drawbacks revealed by the tests in real beam conditions. In this paper we present the results of the tests for the various configuration readout systems to agree with the model and simulation of the detector. In concluding remarks, we will discuss the performance of the prototypes and point out the camerabased one to be the more suitable for the final design.

“…Traditionally the first stage of the detector for an IPM has been a micro-channel plate (MCP) which acts as a charge amplifier [6]. After it is used, each channel in the plate require some time to recover and more importantly the lifetime of each channel is limited.…”

“…This early step to a digital signal is advantageous in many ways and in strong contrast to other ionization profile monitors where the signal is kept analog longer in the signal path. In [6] anode strips are used for the readout which are sampled with an ADC. Before a beam profile measurement is taken, the system background is sampled and stored and later subtracted from the measurements.…”
