The U11 PGM beam line at the Brazilian National Synchrotron Light Laboratory

We present the U11 beam line at the National Synchrotron Light Laboratory (LNLS), Brazil. This is the first undulator based beam line installed at the UVX storage ring. It is based on the collimated plane grating monochromator design, which allows for variation in included angle of the grating. The results obtained during the commissioning demonstrate a good overall performance in terms of energy resolution and beam size, in accord with the expected values obtained from ray tracing calculation.
