The LISA Technology Package (LTP) – LISA Pathfinder’s heart
LISA Pathfinder consists of a science module (top left in the exploded view) and the propulsion module (bottom left), which was ejected upon reaching final orbit. The optical measurement system in LISA Pathfinder – the LISA Technology Package (LTP) – is shown on the right. It comprises two gold/platinum test masses, each enclosed within an electrode housing in compact vacuum chambers of the mission’s science module. The optical bench of the laser interferometer is arranged between the test masses (interval 38 centimetres).
