Quantitative analysis of thin foils using backscattering measurements. [He implants in Pd; composite Al/parylene]
Backscattering of 1.25-MeV protons and alpha particles from thin foils is used for a nondestructive quantitative elemental analysis of thin foils. The detection of helium that had previously been implanted into a 1350 A palladium foil and the analysis of a composite aluminum and parylene foil are presented as examples of this technique.

Test of Proportional Wire Chambers in Hybrid Systems
This is an agreement between the National Accelerator Laboratory and Professor I. Pless of MIT representing the experimenters to provide selected instrumentation for the beam to the 30-inch bubble chamber, and to use the hybrid chamber for an experiment. This document contains an enumeration of the major items needed for the proper execution of Experiment No. 154 as expressed in the proposal for the experiment, subsequent correspondence, and the draft agreement. This agreement covers phases I and II of the experiment. In Phase I the experimenters will design, construct and bring into operation a complete upstream proportional chamber system. This system will tag incident beam particles as to type by correlating the Cerenkov signals furnished by NAL with the proper incoming particle. In addition, the system will measure the position of the incident particle which passed through the momentum slit. The system will contain three proportional wire chambers (3 planes each) which will provide data suitable for defining the incident beam both as to position and angle. The experimenters will furnish the computer, magnetic tape units, programs, and all necessary readout and interface hardware. When the system is installed, debugged, documented and completely functional, it will be turned over to …
