A transverse phase space emittance scanner is proposed and under development for the 1-GeV H^- SNS linac, using a laser beam as a slit. For a 1 GeV H^- beam, it is difficult to build a slit because the stopping distance is more than 50 cm in copper. We propose to use a laser beam as an effective slit by stripping off the outer electron of the H^- (making it neutral) upstream of a bend magnet and measuring the stripped component downstream of the bend magnet. The design and modeling of the system will be discussed. We are expecting to make a preliminary measurement in 2009.

A transverse phase space emittance scanner is proposed and under development for the 1-GeV H^- SNS linac, using a laser beam as a slit. For a 1 GeV H^- beam, it is difficult to build a slit because the stopping distance is more than 50 cm in copper.
