“…The leakage current can amplify by three orders of magnitude to ∼0.1 mA following γ-ray exposures up to thousands of Gy(SiO 2 ). For the case of low energy PDC, such as slapper detonator [6], the voltage of charging source is typically in the range of 1000 to 3000 V, and its output power is usually on the order of 0.1-1 W [4], [18]. After γ-ray exposures, the power consumption in AS-MCT is comparable with the output power of charging source.…”

The MOS-controlled Thyristor (MCT) has been characterized by MOS-gating, high current rise rate, and high blocking capabilities. The anode short MCT (AS-MCT) is distinguished from the conventional MCT by an anode-short structure, which forms an extracting path for the leakage current at the gate-ground and develops a normally-off characteristic. The AS-MCTs are ideal switches for pulse discharge application. As a composite structure made of metal-oxide-silicon and bipolar junction transistors, AS-MCT is susceptible to ionization damage. This work reports the experimental results for the degradation of zero-load (or short) pulse discharge circuit characteristics induced by the ionization damage of its AS-MCT switch following cobalt-60 γ-ray dose up to 9160 Gy(SiO2). The radiation-induced leakage current in AS-MCT accounts for the degradations of charging time and peak surging current of the pulse discharge circuit. These degradations show a "tick"-like dependence on the γ-ray dose which are recoverable after high dose exposures, thousands of Gy(SiO2). From device and circuit physics perspectives, the damages on pulse discharge circuit are modelled, and then, this paper proposes, the mechanism behind the characteristics degradation of pulse discharge circuit from the total ionization dose damage of AS-MCT switch.

Polyimide (PI) is an ideal flyer material commonly used for exploding foil initiator (EFI) systems. The material properties of PI influence the flight ability of the flyer. Curing temperature during the preparation process of PI is one of the key factors influencing the material properties. In this study, we investigated the effect of the PI film curing temperature on the material properties and the flight ability by characterizing IR transmittance, XPS, and nano-hardness. The results show that the flight ability of the flyer is highly dependent on the curing temperature. Curing at 250 C is beneficial for the flyer to have an optimal flight velocity, which was attributed to the good chemical and mechanical behavior of the material. Increase in curing temperature would weaken the material properties to some extent.High-temperature cure (e.g., 400 C), would break the molecular chain and carbonize the material, causing significant drop in flight velocity of the flyer. The study is expected to contribute to the development of high-performance flyer for EFI applications.

The particle size of explosives plays a key role in the short‐duration pulse shock initiation, and explosives with small grain size and large specific surface area (SSA) generally have preferable sensitivity properties. We have constructed a high‐throughput microfluidic recrystallization platform, aiming to prepare ultrafine pentaerythritol tetranitrate (PETN, C(CH2NO3)4) via a precisely controllable solvent/nonsolvent recrystallization process. Through this platform, the recrystallized PETN was produced with a particle size of about 2 μm, and its SSA was above 70‐fold that of the raw PETN. The X‐ray diffraction results indicated that the raw and microcrystalline PETN had a similar diffraction spectrum. The thermal analysis demonstrated that compared with the raw PETN, the microcrystalline PETN revealed better decomposition performances. Importantly, the short‐duration pulse shock initiation sensitivity of microcrystalline PETN pellets was evaluated when subjected to an exploding foil initiator. The shock initiation threshold results were as follows: 50 % initiation voltage U (50 %)=1332 V, the corresponding capacitor storage energy was 195.2 mJ. Furthermore, the calculated shock pressure and shock duration imparting to the pellets were 9.61 GPa and 12.53 ns respectively, corresponding to the 3162 m/s threshold velocity. Finally, the enhanced sensitivity during the shock‐to‐detonation transition was further explained with the hot spot‐based mechanism.
