the unscattered protons from the vertically scattered protons. 2. A spectrometer with a pair of steering magnets to bring protons scattered at all angles from 1 -t 25 mrad back on the spectrometer axis. I now believe that this system is superior to the one I discussed at the October meeting on storage rings at NAL. This earlier system used septum magnets to deflect the unscattered protons in the horizontal plane and had three problems: a) It would be difficult to build the necessary septums. b) The poor field shape of the septums would make operation of the storage rings difficult. cl The system would require two non-cross-over points and would thus require an undesirable change in the overall geometry of the storage rings. I would like to thank Dr FOLEY et al. for suggesting some of the ideas contained in this note. 30, \ \ P..I o6NL CLYDE et al. 24.6 GeV/c &BERKELEY 5 + 7 GeV/c OARGONNE AKERLOF ETALS
