What is the primary purpose of a booster in a fuze system?

The primary purpose of a booster in a fuze system is to amplify the detonation. A booster is designed to enhance the energy output of a primary explosive or initiator, ensuring that the main explosive charge is detonated effectively and reliably. By using a booster, the system increases the likelihood of achieving a successful initiation, especially when the main charge has a higher threshold for detonation. This amplification is crucial in applications where the main explosive is either insensitive or requires a significant output of energy to ensure a complete detonation.

In practical applications, the booster acts as a bridge, providing the necessary additional energy that can trigger more stable and robust explosives, ensuring that munitions function as intended in various conditions.
