Table 4.01 WEDGE TEST LENS AND BOOSTER SYSTEMS<br />

The lens and booster explosive systems used for most of the wedge tests are listed<br />

below, generally in order of increasing pressure output. All lenses, designated by P-<br />

xxx, have plane-wave output. The output face diameter is indicated by the designa-<br />

tion number; for instance, P-040 and P-081 and 4 are 8.1 inches in diameter, respec-<br />

tively. The booster explosive t.hickness also is given.<br />
