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; PB - JACoW Publishing CP - Geneva, Switzerland SP - 205 EP - 208 KW - ion KW - vacuum KW - storage-ring KW - undulator KW - survey DA - 2017/06 PY - 2017 SN - 978-3-95450-188-5 DO - doi:10.18429/JACoW-MEDSI2016-TUPE19 UR - http://jacow.org/medsi2016/papers/tupe19.pdf ER -
