The effect of beta radiation on the susceptibility of high-energy materials to a high-current electron beam

The results of experiments on initiating explosive transformations in layer samples of high-energy materials, which were first irradiated with beta particles, with a pulsed electron beam are reported. The potential to adjust the susceptibility of high-energy materials to an electron beam by performing preparatory ionization treatment is demonstrated.

Initiation of layered high-energy material compositions by nanosecond high-current electron beams

We present the results of experiments on the initiation of ignition by high-current electron beams of nanosecond duration in high-energy compositions representing layers based on potassium picrate and red lead. Successful initiation of the compositions containing potassium picrate has been achieved for the first time.

Influence of nanosized carbon forms on the properties and susceptibility of energy-saturated cobalt salt to a pulsed electron beam

The influence of fullerenes and detonation nanodiamonds on the initiation of complex cobalt perchlorate by a nanosecond pulsed electron beam has been studied. The results on the thermal compatibility of experimental compositions in nonisothermal conditions have been presented.

Electrical explosion of a conductor in energy accumulating phase change materials with nanosized semiconducting additions

The results of experiments on the explosion of a copper conductor in paraffin and wax both without additions and with nanosized copper oxide additions are presented. The experiments provided the size of the channel formed in wax samples upon the conductor explosion and subsequent expansion of the electric discharge plasma. The obtained results testify to the influence of nanosized additions on the character of electric discharge plasma expansion in the formed channel, the strength of composite materials, and the sample fragmentation (destruction).

Graphene As a Sensitizing Additive to High-Energy Cobalt Salt for Enhanced Initiation by a High-Current Electron Beam

We have studied the influence of graphene additives on the initiation of high-energy cobalt salt by a high-current electron beam of nanosecond duration. The high-energy composite was prepared by ultrasonic mixing of 80 wt% cobalt amminate (NCP) and 20 wt % graphene. It is established that the use of graphene as a sensitizing additive in a high-energy composite decreases the necessary energy parameters of the initiating electron beam and increases the energy characteristics and combustion rate of high-energy materials.

Initiation of explosive conversions in energy-saturated nanoporous silicon-based compounds with fast semiconductor switches and energy-releasing elements

The first findings concerning the initiation of explosive conversions in energy-saturated nanoporous silicon-based compounds via the electrical explosion of a semiconductor bridge are presented. The obtained results indicate that the energy parameters of an explosive conversion depend on the mass of a combustible agent—namely, nanoporous silicon—and the silicon-doping type.

Initiation of explosion-induced transformations in energy-saturated materials with nanoadmixtures by a high-voltage electric discharge

We have reported on the results of an experimental investigation of the effect of inert admixtures on the threshold characteristics of the breakdown (initiation) voltage in energy-saturated materials. A physicomathematical model that describes the experimental results has been proposed.

Initiation of combustion in multilayer energetic compositions with a high-current electron beam

Experimental results on the ignition of energetic two- and three-layer potassium picrate- and lead(II, IV) oxide-based compositions with a high-current electron beam of nanosecond duration are reported. It is shown that the sustainability of explosive transformations in layered compositions depends on the boundary conditions and the additional impact of the cathode flame (high-temperature metal plasma).

Investigation of ignition of energy-storage materials by product of electrical explosion of conductors

Experimental results on plasma ignition process for four types of energy-saturated materials by action of electrical explosion of conductors are presented. The burning speed of charges of bulk density of the investigated materials are identified by three methods. It is found that volume combustion takes place.

Effect of electron beams irradiation on thermal properties of energy-storage materials

Experimental results on the impact of electron beam to the powder composition of nitrocellulose and nitro-glycerin and mixtures of this composition with lead oxide and zirconium in varying proportions were presented. Taking into account this experimental data thermal sensitivity of the samples was estimated. The initiation of ignition energy-storage materials using a high-current electron beam was investigated. The decisive role of cathode flare, which is generated from the cathode after the electron beam, in ignition was shown.
