Description

To create better vacuum conditions in the central region of a cyclotron a 20 K cryopump has been designed and built with a 100 K baffle optimized for a high conductance and a low radiation input. The transmission of the baffle is 0.5, the pump speed is 8000 l s-1 for nitrogen. The design techniques and the results are described. (author)
