These experiments frequently employ Mott polarimeters. In the past, Mott polarimeters were bulky, and operated at high voltages (∼150 kV). Modern retarding-potential Mott polarimeters operate in the 20 kV range, and are small enough to be mounted inside a vacuum system. A new, ultra-compact Mott polarimeter is described here which occupies a significantly smaller volume than previous designs. This polarimeter, when equipped with a thorium target and operating with an accelerating potential of 25 kV obtained a figure of merit of ∼1.3 x 10-4, which is similar to the best values achieved by previous Mott polarimeters. Thus this design is well suited for a variety of applications involving angle- and/or energy-resolved polarization measurements.66 p.application/pdfengCopyright is held by the author, unless otherwise indicated.
