What component comes after the primer in the High Explosive Train Process?

In the High Explosive Train Process, the component that comes after the primer is the booster. The primer ignites, creating a small, initial explosion that then activates the booster. The booster enhances the energy of the explosion from the primer, ensuring it is sufficient to initiate the main charge effectively. This sequence is critical for the proper functioning of explosives, as each component plays a specific role in transferring energy and increasing the efficiency of the overall detonation process.

The detonator, while related to initiating the explosive chain, serves as a trigger for the primer rather than following it in sequence. The initiator, similar to the detonator, plays a role in starting the explosive reaction but is used in specific contexts involving nuclear explosives rather than conventional high explosives.
