Interfacing with the LHC accelerator during physics operation

A number of critical LHC machine experiments interface issues are highlighted. Particular emphasis is given to particle losses and their impact on the LHC performance. It will be shown how the risk of radiation induced failures to equipment can be reduced via shielding, radiation tolerant equipment designs and on-line radiation monitoring. Recent data on beam induced backgrounds and radiation at the Tevatron and in CDF (Fermilab) is given as an example.
