New Method for the Observation of Hyperfine Structure of NH3 in a ``Maser'' Oscillator
Weak hyperfine satellites have been observed with very large signal-to-noise ratios when microwave power at frequencies corresponding to these satellites is introduced into a ``maser'' which is oscill...

Gas Scattering in a Strong Focusing Electron Synchrotron
Scattering of the electron beam by the residual gas in the vacuum chamber is calculated for the 1 Bev strong focusing Cornell Mesotron. It is shown that the elastic scattering by the nucleus and the i...

A new type of ion gun is described which greatly improves the resolution of a nonmagnetic time-of-flight mass spectrometer. The focusing action of this gun is discussed and analyzed mathematically. The validity of the analysis and the practicability of the gun are demonstrated by the spectra obtained. The spectrometer is capable of measuring the relative abundance of adjacent masses well beyond 100 amu.
