IBEX Lo Sensor

This photo shows the IBEX Lo sensor in the clean room. IBEX Lo can measure particles with 0.01–2 keV (one-thousand electron volts) of energy and is situated at the top of the hexagon spacecraft. IBEX has two sensors one on each side; IBEX Hi and IBEX Lo. Each time an energetic neutral atom comes in to one of the sensors, it is recorded and at the end of six months of that data it will give scientists a picture of the entire 360 degrees longitude celestial sphere.
