Abstract: Explosion chamber modification is proposed. It is intended for studying detonation and shock-wave processes using synchrotron radiation. Examples of explosive chamber designs that meet the necessary conditions are given. Numerical simulation is used to obtain a dependence between the degree of inhomogeneity of the stress state of an explosion chamber shell and the ratio of the shell radius to its thickness.

Keywords: explosion chamber, synchrotron radiation, numerical simulation, equivalent stresses.
