Abstract :
The MIXE X-ray astronomy detector has experienced high backgrounds on balloon flights although well shielded against atmospheric gamma-rays and charged particles. Monte Carlo simulations show that this can be due to neutron-induced backgrounds in the payload arising from cosmic-ray proton interactions and atmospheric albedo neutrons
