Abstract

A laser wire system has been developed in the Spallation Neutron Source (SNS) superconducting linac (SCL). The SNS laser wire system has a capability of measuring profiles of an operational hydrogen ion beam at 9 cryomodule stations along the SCL by using a single light source. This talk reports our recent study of the laser wire profile measurement performance. Parasitic profile measurements have been conducted at multiple locations of SCL on an operational one-megawatt neutron production beam that SNS recently achieved as a new world record. We will also discuss novel beam diagnostics capabilities at the SNS SCL by using the laser wire system.
