    Spacelab 1

    Area of Science:

    • Cosmic X-ray Astronomy
    • Astrophysics
    • High-Energy Astrophysics

    Background:

    • Observations of cosmic X-ray sources are crucial for understanding high-energy phenomena in the universe.
    • Previous spectral data lacked the resolution to identify fine features.

    Purpose of the Study:

    • To analyze detailed spectral features and temporal variations of cosmic X-ray sources.
    • To investigate galactic binary X-ray sources and galaxy clusters using advanced spectroscopy.

    Main Methods:

    • Utilized a gas scintillation proportional counter spectrometer on Spacelab 1.
    • The instrument covered an energy range of 2-80 kiloelectron volts with 180 cm² geometrical area.
    • Achieved an energy resolution of approximately 9% at 7 kiloelectron volts.
