The CHESS-U upgrade1 project transforms Cornell’s 5.3 GeV, electron-positron colliding synchrotron into a dedicated 6 GeV light source and replaces the current experimental hall contents with six new end stations fed by pairs of canted CHESS compact undulators2 through three new front ends. ADC is responsible for these new front ends (FE), which are comprised of all components involved in safely transporting the x-ray beams from the storage ring (CESR) to the first optical enclosure (FOE) beyond the storage ring shielding wall. Accelerated installation of each FE is achieved by installation and alignment of all components onto a single massive steel I-beam structure; improving on the SPring-8 parallel I-beam concept3. In this paper, ADC will discuss various unique design elements that reduce installation time and optimize the spatial envelope of the front ends.
