UNCLASSIFIED/ /fOR Offl@IAL ~SE 8,.Llf • Tetryl (Nitramine, C7HsNsOs) with p = 1.93 g/cm3. • Landmine - includes plastic explosives, such as Semtex, which is made of ROX and PETN, and C-4, which is made of ROX. B. Nuclear Materials such as natural uranium (U-238) and weapon grade with enriched (U-235). Testing can be done with this natural uranium which can be obtained without special restrictions. C. Drugs like Cocaine (C17H21 NO4) and Heroin ( C21H23NOs ) are of high in C and H, low in O and low-medium Cl densities. O. Common articles such as ethanol alcohol/wine (C2H5Q) with p = 0.789 g/cm3, clothes like silk (C3H11N3Q5) with p = 0.789 g/cm3, and nylon (C5H11NO) with p = 1.1 g/cm3, and metal utensils, including knives. The list provides a guide for use of articles for simulation testing in the IEC inspection station. Fortunately, the combination of sources in the integrated station provides good coverage of this wide variety of items. Conventional single source units suffer " gaps" in coverage. Pulsed Power for the Inspection Station Advanced materials and methods are used in its design to minimize weight and size. This extends use of stationary units (e.g. at airports) to mobile platforms such as vans, law enforcement vehicles or light military trucks. Figure 5.1 shows a block diagram of the power control circuits. Figure 5.1. Block Diagram of the IEC Pulsed Power System The power is taken from the platform power system and can be either 12-48 VOC or single phase 120 VAC. The high voltage power supply is a solid-state switch-mode inverter followed by a voltage multiplier circuit that incrementally steps the voltage up a series of capacitors fed by high voltage diodes. The energy storage unit is composed of high voltage capacitor segments with a low series inductance and resistance. The capacitor bank is charged and discharged at the pulse repetition rate. The custom capacitor sections are engineered to withstand the mechanical stress caused by rapid charge/discharge cycling. The nominal capacitor bank voltage is 120 kV at full pulse power output. A triggered spark gap is used to switch rapidly a high-energy pulse of current from the capacitor bank to pulse modulate the magnetron. The triggered gap is a compound three-element spark gap design. The arc is sustained until the capacitor UNCLASSIFIED//FOR OFFI&IAk W&E 8PtkY 49
