Numerical simulations of possible fault conditions in the cryogenic operation of the TTF/FEL - and Tesla linear accelerators

摘要

The cryogenic designs of the existing superconducting TTF/FEL linear accelerator and the future TESLA linear collider have to include fault scenarios like the sudden loss of insulation vacuum or the venting of the beam tube. As long as relevant cryogenic components are not available for specific tests, there is the need for numerical simulations of possible fault scenarios. An object oriented computer code has been developed in order to correspond to the real fault conditions as close as possible. Some results of the calculations for the TTF/FEL and TESLA linear accelerators are presented and discussed.
