1. Method for generating a pressure cell configured for working according to the piezo-resistive principle and for use under high-energy radiation, particularly for use under cosmic radiation, wherein the pressure cell is of the type that exhibits a radiation-induced drift of at least one of a change in sensitivity of the pressure cell and a change in an offset measurement parameter of the pressure cell as a function of a radiation dose of high-energy radiation exhibited on the pressure cell,
wherein
the method comprises an exposing of the pressure cell with a radiation dose of high-energy radiation up to a start of a saturation range of the radiation-induced drift, wherein the radiation-induced drift asymptotically approaches within the saturation range a limit value with increasing radiation dose of high-energy radiation exhibited on the pressure cell.
