Experiment 8 was designed to measure the total cross sections and the small angle cross sections for charged pions on C-12, Ca-4, and Pb-28. Particles can be detected from to 35 degrees on one side and from 1 to 18 degrees on the other side of the beam except near 75 degrees which is parallel to the plane of the target. A scintillator can be inserted on the small angle side to detect particles that miss the target. Any one of four target positions can be selected at the remote control, either of three targets or the target out position. This chamber can accept a beam of dimensions up to 3 by 5 inches. It was helium filled to reduce multiple scattering and to protect the calcium target. By measuring the total cross section and the small angle differential cross section, both the real and the imaginary parts of the forward scattering amplitude, f(°), can be determined.62 ppengCopyright is held by the author, unless otherwise indicated.
