DCX stands for Double Charge exchange between source beam particle and target particle. in this experiment, the charge of Beryllium-9 with transfer to Oxygen-18, makes it becomes Neon-18 and the Be-9 becomes He-9. Carbon-12 also used.

in these 2 days, we aligned the beam such that the target is on the beam position. closing the tubes and vacuums it. quite simple tasks, but it take time.
