Conclusion
• Passage of low-energy charged particles through GAMMA-400 gamma-telescope thermal insulation and two-layer plastic scintillation detectors used as anticoincidence shield was modeled
• 84% of 1 MeV electrons were fully absorbed by thermal insulation• Other modeled particles are absobed by the anti-cincidence systems.• Low-energy charge particle detectors should be put outside of thermal
insulation.
