Radial Time Projection Chamber (rTPC)
The radial Time projection chamber will measure the position ofanti-hydrogen annihilations by detecting the trajectories of particlesproduced in the annihilation reactions. This will be used to study thegravitational force on antimatter in the Alpha-g experiment. (Image: CERN)

rTCP - what's that? It's a component in ALPHA-g!

The turquoise cables are fibreoptic data lines to communicate to the microchips on the detector.
