Elliptically Bent X-Ray Mirrors with Active Temperature Stabilization

Figure 4

Characteristic functions of the test mirror benders measured with the DLTP: for the left-hand-side (upstream) bender (fA) and for the right-hand-side (downstream) bender (fB). Springs driven by Picomotors control the bending forces applied to the mirror. For convenience and linearity, we measure the Picomotor travel (in μm) directly, using an LVDT for feedback. Thus, the unit here is slope/μm of Picomotor travel.
