  The ISIS Spallation Neutron Source has been in operation at the Rutherford Appleton Laboratory for over 25 years. Much of the original equipment installed during the construction of the facility is still in operation. The window separating the proton beam transfer line from the neutron target is a key component in the accelerator complex. During the operational life of the Beam Entry Window it has absorbed a considerable amount of energy deposited from the proton beam as it passes from the accelerator vacuum to the target area. Due to the difficulties in accessing and handling the window assembly, a decision was made to replace this component in a planned maintenance period. This paper describes the specialist remote handling equipment and techniques that were developed during the 3 year build up to the removal and replacement of the of the highly active Beam Entry Window.
