Development of a long trace profiler at SPring-8 using a newly developed slope sensor

The long trace profiler (LTP) at SPring-8 has been upgraded using a newly developed laser-based slope sensor for precise measurements with high spatial resolution. Simulations of centroid calculation in the slope sensor have been performed to evaluate the ultimate accuracy of slope measurement. A performance test of the LTP has also been performed, and a spatial resolution of 0.6 mm has been confirmed.
