|The unique characteristic of the AALGG at The Open University is its tilting frame, allowing firing of the AALGG from its horizontal position through any angle to fully vertical, allowing impacts into loose material to be made. Three target chambers are used: a small chamber (allowing ~13 cm diameter targets), a medium sized chamber (up to 50 cm diameter targets) and a large chamber (up to 2 metre targets). cryogenic cooling within the chambers allows impacts into extremely low temperature ice to be performed, relevant to simulation impacts into icy moon surfaces.|
Capable of firing projectiles up to 4mm in diameter at velocities of ~5 km s -1. Applications include recreating impacts from small-scale space debris and also simulation of larger impact events.
