Abstract

A jet cutter apparatus and method for using a single bridge wire or a plurality of bridge wires to uniformly detonate a booster and thereby cause a uniform detonation of the explosives adjacent to the liners, thereby causing a uniform compression of the liners to form a uniform plasma jet that is substantially radially perpendicular to the jet cutter.

First claim

What is claimed is:

1 . A detonation wave shaper comprising:
An explosive pellet; An exploding bridge wire contained within the explosive pellet.

2 . The detonation wave shaper of claim 1 wherein the explosive pellet is substantially cylindrical in shape.

3 . The detonation wave shaper of claim 2 wherein the exploding bridge wire is substantially coaxial with the explosive pellet cylinder.

4 . The detonation wave shaper of claim 2 wherein the exploding bridge wire extends through most of the length of the explosive pellet cylinder.

5 . The detonation wave shaper of claim 1 further comprising a shell surrounding the explosive pellet.

6 . The detonation wave shaper of claim 5 wherein the shell is comprised of a conductive material and a first end of the exploding bridge wire is electrically connected to the shell.

7 . The detonation wave shaper of claim 6 wherein a second end of the exploding bridge wire is adapted to electrically connect to a fireset.

8 . A shaped charge tubing cutter comprising:
a substantially cylindrical housing; a shaped charge explosive having an explosive and a liner; a detonation wave shaper comprising an explosive pellet and an exploding bridge wire contained within the explosive pellet; wherein the detonation wave shaper fits in a cavity in the center of the shaped charge explosive.

9 . The shaped charge tubing cutter of claim 8 wherein the detonation wave shaper further comprises a substantially cylindrical shell encasing the explosive pellet, wherein the exploding bridge wire is substantially coaxial with the explosive pellet.

10 . A detonation wave shaper comprising:
An explosive pellet; A plurality of exploding bridge wire segments within the explosive pellet.

11 . The detonation wave shaper of claim 10 wherein the explosive pellet is substantially cylindrical in shape.

12 . The detonation wave shaper of claim 11 wherein the exploding bridge wire segments are substantially coaxial with the explosive pellet cylinder.

13 . The detonation wave shaper of claim 13 wherein the exploding bridge wire segments are arranged substantially end-to-end and extend through most of the length of the explosive pellet cylinder.

14 . The detonation wave shaper of claim 10 further comprising a shell surrounding the explosive pellet.

15 . The detonation wave shaper of claim 14 wherein the shell is comprised of a conductive material and a first end of the exploding bridge wire segments is electrically connected to the shell.

16 . The detonation wave shaper of claim 15 wherein a second end of the exploding bridge wire segments is adapted to electrically connect to a fireset.

17 . The detonation wave shaper of claim 10 wherein the exploding bridge wire segments are mounted on a printed circuit board.

18 . The detonation wave shaper of claim 17 wherein the explosive pellet is substantially cylindrical in shape.

19 . The detonation wave shaper of claim 18 wherein the exploding bridge wire segments are substantially coaxial with the explosive pellet cylinder.

20 . The detonation wave shaper of claim 13 wherein the exploding bridge wire segments are arranged substantially end-to-end and extend through most of the length of the explosive pellet cylinder.

21 . The detonation wave shaper of claim 18 wherein the exploding bridge wire segments are mounted on alternate sides of the printed circuit board from a first end of the printed circuit board to a second end of the printed circuit board.
