The Medium Resolution Proton Spectrometer (MRS) at the Los Alamos Meso
n Physics Facility (LAMPF) was used to develop a position-sensitive pr
oton telescope with CsI(pure) crystals. Photomultiplier tubes were mou
nted at both ends of a 7.5 x 15 x 30 cm long proton telescope and posi
tion measurements using the difference of the time signals were perfor
med. The position resolution was measured to be 2.5 cm FWHM. An energy
resolution DELTAE/E = 3 to 4% was measured.
