The Arc transport line, which brings high-energy, high-intensity electron and positron bunches from the SLAC (Stanford Linear Accelerator Center) linac to the Stanford Linear Collider (SLC) final focus section, has been in operation for the past few

Luminosity is to be produced at the SSC collider by crossing with finite angle the counter circulating proton beams at each interaction point (IP). Such a crossing angle introduces unwanted dispersion in the high beta triplet quadrupoles adjacent to

We review the important changes made to the optics of the interaction regions (IRs) in the collider since the conceptual design (SCDR) of 1990. The most significant modification is a new procedure for the /spl beta/ squeeze. Three additional families

We address the issue of correcting higher order chromaticities of the collider with one or more low /spl beta/ insertions. The chromaticity contributed by the interaction regions (IRs) depends crucially on the maximum value of /spl beta/ in the two I
With a newly developed algorithm using resonance basis Lie generators and their evaluation with action-angle Poisson bracket maps (nPB tracking), we have been able to perform fast tracking for dynamic aperture studies of PEP-II lattices as well as in

The high luminosity interaction regions (IRs) are an important part of the lattice in colliding beam machines. The performance of the collider may depend significantly on the particular design of the IRs. In this paper we discuss the general principl

The use of ZLIB to effect the translation of the tracking section of the SSCTRK kick-drift code to a mapping construction and map tracking code shows that ZLIB is a user-friendly, effective, and efficient way to build and track truncated Taylor maps.

Heavy-water reactors are well adapted to produce relatively large quantities of weapon grade plutonium. Several nonnuclear nations have created plants for uranium enrichment at a level sufficient to produce a few bombs per year, such nations could pr

A study has been made of scattering of 40 protons and 160 mesons in photographic emulsions in order to determine the mass of the individual particles. The spread in the values so obtained is large, but the evidence suggests that the majority of meson
