Beam and prone detonator capsules are products that create an explosive impulse and are designed to excite detonation of charges of a blasting explosive. Beam and detonator capsule detonators have essentially the same device.
Beam and detonator capsule detonators, purpose, general device, internal charge.
The main elements of detonator capsules are: shell (cap), coating (cup), charge. The shell of the detonator capsule is made of cupronickel, copper or aluminum. The shell thickness is 0.1-0.7 mm. Shells can be with a side, without a side, with a carving. Depending on the method of attaching the detonator capsule to the location.

The coating is in the form of a cup of copper, brass, aluminum. At the bottom of the cup of the radiation detonator capsules there is a hole closed with a silk net or nitro lacquer and designed to facilitate the breakthrough of the flame beam to the capsule charge. The cup of the detonator capsule caps has a solid, but in the central part, thinner bottom, which facilitates piercing with a sting.
The detonator capsule charge is usually combined and consists of a primary charge and a secondary charge. The primary charge located in the cup consists of lead azide in an amount of 0.2-0.4 grams. To increase the sensitivity of radiation detonator capsules to a flame beam, 0.02-0.08 grams of TNRS, lead styphnate are placed on top of the primary charge.
The detonator capsules are named according to the type of fuses in which they are used, either by numbers or by the design of the shell and the composition of the charge. For example, in the subversive case, radiation caps detonators KD No. 8 are widely used.

In artillery ammunition, TAT radiation capsules are used: TAT-1, TAT-2, TAT-02. The number (1.2, etc.) indicates the number of the sample capsule, “0” means that the shell is without a rim. In the alphabetic part of the index: the first “T” TNRS, lead styphnate, “A” – lead azide, “T” ten or tetryl.
In the detonator capsule capsule, 0.04-0.06 grams of the capillary sensitizing composition containing TNRS, tetrazene, barium nitrate and antimony is placed on top of the azide of lead. In some types of detonating detonator capsules, the primary charge is explosive mercury in an amount of up to 1 gram.
The secondary charge placed in the shell is made of ten, tetryl or hexogen and other powerful highly sensitive blasting explosives. The mass of the secondary charge is 0.3-0.5 grams, and in subversive detonator capsules from 0.5 to 1.0 grams. For engineering work, explosive mercury explosive detonator caps of the GRT type are used..
