Photoemission study of metal-doped beta-boron thermoelectric materials

In the period August 13 to 17, ten shifts on beam Line U-7 were assigned to perform photoemission measurements of V-doped boron materials. All the beam time, however, was consumed in detecting leaks in the experimental chamber. After all possible leaks were mended, the background pressure was still high and the beam time had expired. A major leak in the monochromator section was later detected.
