Small bore magnets will require low conductance vacuum chambers. Conventional vacuum pumps will have to be assisted by distributed pumping provided by Non-Evaporable Getter (NEG) coating. The time constraints for design, prototyping, pre-assembly, installation and commissioning of the new systems require simple solutions and the use of existing expertise where possible. In this paper the draft layout of the vacuum system will be explained, information about the expected dynamic pressure distribution and conditioning will be given. Some technical solutions to resolve specific issues arising from the small vacuum chamber dimensions and the dense arrangement of components are described.
