AB  - A compact X-ray emission spectrometer (mini-XES) has been designed and fabricated for use at the Brockhouse undulator beamline*. The mini-XES uses cylindrical von Hamos geometry tuned for Fe K-edge and uses a Pilatus 100 K area detector from Dectris**. It is based on a general design implemented at the APS***. The mini-XES design was developed to be as simple to fabricate and as easy to operate as possible. We tried to minimize the number of components, so there are only two main parts that create a chamber. Those two components are joined and aligned by a NW-80 flange. From the beginning, the design was trying to achieve no tools assembly, alignment, and operation. For lower precision alignment we decided to use the centering ring of the NW-80 flange which, together with two posts integrated with the chamber, provides an adequate method for joining the two parts of the enclosure. We use level vials for horizontal adjustment of the holder for the 10 crystals. For high precision alignment of the holder of the crystal, we used the Thorlab KC1/M kinematic mount, which had the adjustment screws accessible from outside of the chamber. The fabrication was done in-house using uPrint SE Plus 3D Printer****. The first tests of the spectrometer were completed in the Brockhouse wiggler beamline and were successful. Future improvements will aim to reduce the background scatter and better position the detector, to improve the fill. Now that the relatively inexpensive design was tested and tried, there is an option to upgrade it to 3D printed tungsten or steel version that would intrinsically provide the required shielding.
