Breathing modes in HEMP thrusters
Open accessAbstract
HEMP thrusters develop breathing mode oscillations with frequencies in the 100 kHz range during stable operation in test facilities. The mechanism of those oscillations in the HEMP-T DM3a model, developed by Thales Deutschland GmbH, is investigated using a fully kinetic PIC-MCC simulation model. The formation and time evolution of a breathing mode are discussed. The consequences for stable thruster operation are outlined and the oscillation frequency is compared to a 0D predator–prey oscillation frequency estimate. A comparison with an experimental discharge current measurement of a breathing mode is discussed.

The ECCOPIC code was verified in an international Hall thruster-related benchmark involving several codes and validated with experimental data, demonstrating the method's functionality.
“The ECCOPICcode employed in Refs. 119, 142, 143, and 331 was verified in an international HT-related benchmark involving several codes 84 and validated with experimental data 119,331 , demonstrating the method's functionality.”
From Plasma propulsion modeling with particle-based algorithms (2023) · cites this paper as [84]
The Simulation results section compares the simulation with HEMP-thruster measurements and reports that it reproduces an optical breathing feature observed experimentally. But the Conclusions and outlook section says the simulated breathing frequency and amplitude differ substantially from measurements. Our copy does not identify the code as ECCOPIC or document its participation in an international multi-code benchmark; the citing sentence attaches a separate reference to the benchmark. (LLM, conf=0.84)
Experimental — accuracy not yet measuredThe LANDMARK project benchmarks, reproduced by seven research groups, allowed comparative evaluation of PIC algorithms and showed capability to capture time evolution of MTSI and ECDI with minimal difference.
“These benchmarks, reproduced by seven research groups worldwide, also allowed a comparative evaluation to examine the efficiency of the implementation of PIC algorithms (type of parallelization, Poisson's solvers, explicit vs implicit algorithms, CPU compared to GPU architectures, etc. 84,99 ). Fig. 4 illustrates a comparison of the twodimensional radial-azimuthal simulation results implemented by”
From Plasma propulsion modeling with particle-based algorithms (2023) · cites this paper as [84]
The Simulation model and Conclusions and outlook sections describe one PIC-MCC simulation of breathing modes in a HEMP thruster, not a multi-group benchmark. Searches for LANDMARK, seven research groups, MTSI, and ECDI found no passage addressing the attributed comparison of PIC algorithms or the claimed agreement in time evolution. (LLM, conf=0.76)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
