Sources and Effects of Radiation in Space

Sources and Effects of Radiation in Space

• Sources and Effects of Radiation in Space

• Designing and Testing a of a Space Craft Instrument

• Initial Results and Expected Goals of this Work

SEP’s are mainly protons.

• SEP’s are mainly protons.

• Some SEP’s are accelerated during a solar flare.

• Others are created as a result interactions in the solar wind.

• SEP’s come in short bursts.

• Particle energies can vary from KeV to MeV (eV stands for electron volt)

Sources outside of the solar system

• Sources outside of the solar system

SEP events happen more frequently during solar maximum

• SEP events happen more frequently during solar maximum

• But…..

• GCR’s are deflected more by the Suns magnetic field during solar maximum
