Apparatus and method for radiation-chemical modification of flat meltable polymer samples by means of an electron beam

Device for radiation-chemical modification of flat fusible polymer samples using an electron beam, comprising a housing having a radiation window on a radiation-resistant metal film as a sample carrier, which is arranged slightly curved in the housing and which is electrically heated by a heating current is passed directly through the metal foil, at least a connection for coolant and / or purge gas, and a non-contact temperature sensor which is directed onto the matt black formed sample support base and which is arranged outside the beam path of the electron beam, wherein the housing is mounted on a transport system under an electron accelerator.
