Abstract

Electron string ion source (ESIS) KRION-6T is one of the main parts of the NICA injection complex [1]. During the work on creation of a new ion source for the NICA/MPD project the new ion motion control system was developed, produced and successfully put into operation. Modules development process and operation results are described.

Highlights

  • The Electron String type of Ion Sources (ESIS), was developed, constructed and tested firstly in the Joint Institute for Nuclear Research [2]

  • ESIS KRION-6T is currently designed at LHEP JINR in order to produce heavy ions [3]

  • General description Ions injection, holding and extraction control system contains several types of modules connected via RS-485 Modbus interface

Summary

Introduction

The Electron String type of Ion Sources (ESIS), was developed, constructed and tested firstly in the Joint Institute for Nuclear Research [2]. ESIS KRION-6T is currently designed at LHEP JINR in order to produce heavy ions [3]. KRION-6T operation is based on step-by-step ionization of the ions by hitting with electrons of an electron string and the main task is to produce the Au32+ ions for the NICA/MPD project. During the preparation of physics experiments with the ion source KRION6T, it is necessary to apply special potential distribution for particle ionization and complex signal for beam extraction (Figure 1). 2. General description Ions injection, holding and extraction control system contains several types of modules connected via RS-485 Modbus interface. Each module has its own Modbus ID
