A total absorption scintillation counter for high‐energy photons has been developed with ±7% energy spread for 130‐MeV photons. The counter was built of enough plastic scintillator to contain most of the energy and maintain a high detection efficiency. We employed the technique of observing a statistical sampling of light from an integrating volume. The integrating volume was obtained by painting the surface of the counter with a diffuse reflector and detecting the light with a large number of photomultiplier tubes placed symmetrically about the counter. Use of a scintillator enabled us to work with a light source of high intensity, thus assuring optimum photon statistics.
