A Thin Lens Model for ChargedParticle RF Accelerating Gaps
Abstract
Presented is a thinlens model for an RF accelerating gap that considers general axial fields without energy dependence or other a priori assumptions. Both the cosine and sine transit time factors (i.e., Fourier transforms) are required plus two additional functions; the Hilbert transforms the transittime factors. The combination yields a complexvalued Hamiltonian rotating in the complex plane with synchronous phase. Using Hamiltonians the phase and energy gains are computed independently in the pregap and postgap regions then aligned using the asymptotic values of wave number. Derivations of these results are outlined, examples are shown, and simulations with the model are presented.

Exact Analysis to any Order of the Linear Coupling Problem in the Thin Lens Model
Despite the very simple form of the equations of motion and the knowledge that the motion is exactly integrable, the complete solution of the linear coupling problem in a practical form remains an outstanding issue. 
Algebraic theory of beambeam interaction in the thin lens model
In this paper we will set up a general model for the study of beambeam interactions. First, we described the ring as made of N generalized interaction points (or GIP). These GIP's could be single IP or clustered IP's. They are equally spaced. Then we assign to the i{sup th} GIP two generalized bunches (or GB) {l brace}{rvec {phi}}{sup i}, {rvec {psi}}{sup i}{r brace}. These two GB are colliding at the center of the i{sup th} GIP. The GB can contain many bunches. This allows for the study of long range effect as well as clustered IP's within the GP.more » 
Effect of energeticchargedparticle bombardment on the properties of thin films of highTc superconductors. Final technical report
The effects of lowfluence ( < 10 U/sq cm) 63MeV H(+) and 65 MeV He2 irradiation of prototype thin films of YBa2Cu3O(7  delta), produced by a plasma arcspray technique are examined. The observed change in the resistance versus temperature behavior is much more dramatic than that observed for films produced by other techniques and resembles qualitatively a bondpercolation threshold. The radiation sensitivity of these plasmaarc spray films is concluded to be due to poor intergranular characteristics. This information is being used to modify the processing steps to improve the properties of films produced by this technique. In contrast, highenergymore »
