The protection system for superconducting magnets and bus-bars is an essential part of the LHC machine protection and ensures the integrity of substantial elements of the accelerator. Due to the large amount of hardwired and software interlock channels the dependability of the system is a critical parameter for the successful exploitation of the LHC. The paper will report on observed failure modes, present fault statistics and discuss the overall performance of the protection system during LHC operation in 2010 and 2011. Foreseen measures for further improvements and operational results obtained with already implemented system upgrades will be described.

The Australian Synchrotron Light Source has enjoyed several years of stable operations with a high degree of availability. It is now time to move towards top-up operations to improve the stability and integrated flux of the photon beam. This paper describes the steps that have been taken and what remains to be done in order to implement top-up injection as the normal operation mode for the first user runs of 2012.
