Abstract
The latest modifications of the Medium Energy Beam Transport (MEBT) emittance scanner and the test results are presented. The scanner consists of a slit and harp placed in the MEBT section of Spallation Neutron Source (SNS) Linac with H- energy of 2.5 MeV. It was initially commissioned during the early days of SNS. The initial design allowed to get information about beam core but was incapable of getting precise data about halo. Several improvements in hardware and software were performed recently. They significantly increased signal to noise ratio, reduced harp wires electron coupling and increased scan speed. The latest measurements with the new system show a good agreement with the simulation results from simple models.
