The multiplate carbon polarimeter on the base of the optical spark chambers
with automatic television data acquisition is proposed to be used as a neu
tron polarimeter in the neutron energy range T-n = 200-800 MeV.
The computered analyzing scattering efficiency is more than 0.03 for the po
larimeter design included 20 carbon plates with full carbon thickness d(c)
similar or equal to 100 g/cm.
