The planned upgrade for the ISIS Spallation Neutron Source First Target Station requires a complete redesign of the Target, Reflector and Moderator (TRaM) system whilst working within the constraints set by the existing Void Vessel and target station infrastructure. This talk focusses on converting the optimised simulated design for the TS1 project target into a physical reality that will be robust and give a reliable service life equal to or greater than the existing TS1 Target (>5 yrs).

... as the advantage of having its own 'Target Manufacturing Facility' (TMF). The experience it has gained from manufacturing ISIS current TS1 & TS2 targets has been invaluable in identifying potential manufacturing challenges that must be overcome at the design stage. The Target Design Group (TDG) has worked very closely with the TMF to test design ideas and develop techniques. This has culminated in a target design suitable for manufacture. The target design presented here is a work in progress that has now reached the prototype stage and closely resembles the final product. It is the result of a close collaboration between the Neutronics, Engineering Simulation, Engineering Design and Target Manufacturing Groups. The aim is to deliver a target that can be readily manufactured and is reliable in operation without compromising neutronic efficiency.
