Using the data collected, scientists can better prepare their experiments to operate during glow situations. Spacecraft in orbit are subject to many different types of cosmic radiation. If not properly shielded, this radiation damages sensitive electronics. The objective of the ECT experiment is to characterize the rate and energy levels of such radiation, allowing better radiation modeling, and thus better shield designs. ECT consists of many layers of photographic film, separated by sheets of lead.
Radiation passes through, exposing the film.
Some of the energetic radiation particles will impact the lead, creating a series of less energetic secondary particles that will be detected by the film.
