SEE testing of candidate electronic components for space applications is essential part of a spacecraft radiation hardness assurance process in terms of its operability in the harsh space radiation environment. The unique in Russia SEE test facilities have been created to provide SEE testing. The existing ion beam monitoring system has been presented at IBIC 2017, however, it has a number of shortcomings related to the lack of reliable online ion fluence measurement on the DUT, and inability to measure energies of the high-energy (15-60 MeV/nucleon) long-range (10-2000 µm) ions on the DUT. The paper presents the latest developments and their test results of the ISDE and JINR collaboration in the field of flux online monitoring (including, on the DUT) during tests using scintillation detectors based on flexible optical fibers, and measuring ion energies by the method of total absorption in the volume of scintillation or semiconductor detector. The modernization of the standard beam monitoring procedure during tests is proposed.

Long-term stability is one of the most important properties of the BPM readout system. Recent developments on pilot tone capable front end have been tested with an established BPM readout electronics. The goal was to demonstrate the effectiveness of the pilot tone compensation to varying external conditions. Simulated cable attenuation change and temperature variation of the readout electronics were confirmed to have no major effect to position data readout. The output signals from Elettra front end (carrier frequency and pilot tone frequency) were processed by a Libera Spark with the integrated standard front end which contains several filtering, attenuation and amplification stages. Tests were repeated with a modified instrument (optimized for pilot tone) to compare the long-term stability results. Findings show the pilot tone front end enables great features like self-diagnostics and cable-fault compensation as well as small improvement in the long-term stability. Measurement resolution is in range of 10 nanometers RMS in 5 Hz bandwidth.
