A resistive wire probe is being developed which yields a continuous detonation velocity history of high explosives. Molecu-Wire Corporation makes a No. 40 B and S resistive wire which is partially insulated by a skip-wound nylon thread. Recent work has shown that this wire, inside a copper or brass tube, becomes quite sensitive to varying high explosive shock variations. This study made shot-to-shot comparisons and measured detonation velocity with both streak camera and timing switches. The electronics basically consists of a differentiating operational amplifier. Results from this system were compared to results obtained by mathematically differentiating the same record by use of a computer.
