Displacement Damage Test for Space Application

Experimental Study of Displacement Damage Test for Space Application

Talk summary: In order to evaluated the displacement damage on device induced by energetic particles in
space, various device samples including optocouplers, solar cells, and bipolar transistors are
irradiated with protons, neutrons and γ-rays.

The electrical parameters were measured before
and after irradiation. The degradation induced by different radiation sources is compared and

The test plan is recommended to evaluate device displacement damage for space
