Abstract
An exploding bridge wire detonator for use in high temperature downhole oil well tools is set forth. It is made of a high temperature stable secondary explosive which will be exposed to extremely high ambient temperatures such as 500.degree. F. This apparatus includes a housing supporting a pair of conductor wires which connect with a sacrificial exploding bridge foil or wire connected across the conductor wires. The sacrificial bridge is immediately adjacent to the explosive material in cylindrical form, and a reflector is included therein. The reflector preferably has high shock impedance to reflect shock waves traveling through the explosive from the exploding bridge. The reflector is transverse to the explosive mass but does not fully block off explosive shock wave propagation through the explosive material.
