Recent UK government funding has facilitated the construction of Phase 1 of a unique FEL accelerator test facility (CLARA – Compact Linear Accelerator for Reserach Applications). This test facility will allow the UK to reserach a variety of FEL operating modes to establish a roadmap for the UK and its plan to build a UK FEL user facility.
This paper will look specifically at the vacuum system design of this unique accelerator detailing the challenging design of the photoinjector, the FEL section and the possible use of NEG coating and the requirement for implementing a differential pumping scheme to separate two vacuum systems with 3 orders of magnitude pressure difference over 50 cm. Many other aspects of the accelerator design will be described and data showing the ’real’ perfromance of the accelerator presented.
