  A predominantly electric storage ring with weak superimposed magnetic bending is shown to be capable of storing two different nuclear isotope bunches, such as helion and deuteron, co-traveling with different velocities on the same central orbit. ‘‘Rear-end’’ collisions occurring periodically in a full acceptance particle detector/polarimeter, allow the (previously inaccessible) direct measurement of the spin dependence of nuclear transmutation for center of mass (CM) kinetic energies ranging from hundreds of keV up toward pion production thresholds. These are ‘‘rear-end collisions’’ occurring as faster stored bunches pass through slower bunches. An inexpensive facility capable of meeting these requirements is described, with nuclear channel h + d arrow α + p as example.

  Utilizing the measurement of coherent betatron oscilla-tion phase has emerged as a fast and precise approach for identifying and rectifying errors in achieving a desired lattice in CESR (Cornell Electron Storage Ring), using TAO analysis program and BMAD subroutines. One key advantage of betatron phase measurement over ¿ meas-urement is its sensitivity to phase variations between detectors. This software package has been successfully implemented for the Recycler Ring at Fermilab, with the adaptation of different hardware installations. By em-ploying this technique, a linear model of the bare Recy-cler ring was established, enabling the correction of quadrupole errors.
