Development of a a YAG/OTR Monitor

To investigate the mechanisms of beam halo formation and its dynamics, a YAG/OTR monitor has been developed and tested at the KEK-ATF. The monitor has four ceramic Ce:YAG  screens for the visualization of the beam core and beam halo and an OTR target to provide complementary beam core measurements....

Sumario:To investigate the mechanisms of beam halo formation and its dynamics, a YAG/OTR monitor has been developed and tested at the KEK-ATF. The monitor has four ceramic Ce:YAG  screens for the visualization of the beam core and beam halo and an OTR target to provide complementary beam core measurements. A high dynamic range (>10$^5$) and a high resolution (< 10µm ) have been demonstrated experimentally. Measurements of beam halo using this monitor are consistent with previous results and theoretical modeling, and have allowed further progress in the characterization of the driving mechanisms.
