Abstract

A simultaneous linear initiation mechanism (SLIM). The SLIM includes a first layer. The first layer includes a port, where the port passes through the first layer and is configured to receive a first high explosive. The SLIM also includes a second layer. The second layer includes one or more traces, where the one or more traces include channels within the second layer configured to receive a second high explosive and two or more destination points, where the two or more destination points are the terminal ends of the one or more traces. The SLIM further includes one or more saddle blocks. The one or more saddle blocks include one or more traces, where the one or more traces include channels within the saddle block configured to receive a third high explosive and multiple outlets, where the multiple outlets are configured to receive the third high explosive.
