In the Fall of 2015 a 4800 mm long NEG coated chamber was installed in the Canadian Light Source in cell 9 straight section. The chamber will occupy to majority of the straight length. The chambers vacuum has been monitored for +1 year and no obvious issues has been found. The chamber body is 10 mm thick and the aperture is an ellipse with a 8 mm height and a 65 mm width. A design feature of the chamber is a lack of support in-between the ends of the chamber. The lack of support space is due to the double elliptically polarizing undulator (54 mm, and 180 mm period). This proceeding details the following: a.The structure design and Finite Element Analysis for the deflection and strength; b.Heat loads and cooling calculation; c.Supports design; d.Deflection and correction with the supports; e.Current strips installation f.Activation;
