APPLE-II Undulator Supply and Installation for Diamond-II Beamline K07

Diamond Light Source (DLS), located on the Harwell Science & Innovation Campus in Oxfordshire, is upgrading to Diamond-II to enhance its world-class research capabilities. This procurement seeks a supplier to design, manufacture, test, and deliver one complete eight-axis out-of-vacuum APPLE-II undulator for beamline K07. The undulator must feature a permanent magnetic structure with a 64 mm period length, operate across a physical gap range of 14 to 65 mm, and meet all specified performance requirements. The supplier must provide comprehensive documentation and drawings to enable DLS staff to independently operate and maintain the insertion device without ongoing external support. This is a key component of Diamond-II's upgrade programme, which aims to deliver transformative improvements in speed, spatial resolution, and user access to enhanced instruments for life and physical sciences research.
