The Langmuir method with the use of electron bombardment of a skull crucible has been developed for the determination of the accommodation coefficients of liquid metals. To test the method copper was chosen as one of the most studied substances in terms of ps – Ts data, where ps is the saturation pressure and Ts is the saturation temperature. In order to find the vaporisation coefficient (α) of liquid copper, studies were made on a skull crucible surface heated with an electron beam in a vacuum chamber in the continuous operation mode of an electron linear accelerator.
