Preliminary report on the design of the Superconducting Super Collider

Preliminary report on the design of the Superconducting Super Collider

Date: January 1, 1986
Creator: unknown
Description: While a rather detailed Conceptual Design Report will be available in April, an Superconducting Super Collider (SSC) it is appropriate to give a preview, now that the primary parameters for the Conceptual Design Report have been put down. In this preview the leading two chapters give the historical and scientific-technical background for the SSC and deal at somelength with the physics issues to be explored by the SSC. A third chapter reviews briefly the engineering and accelerator physics foundations for the developing SSC design, while the fourth lists the primary design parameters and describes the overall design. The fifth chapter describes briefly the principal engineering systems that will appear in the Conceptual Design Report, including the rather extensive injector system required. A sixth and final chapter outlines the beginnings of a ``construction plan`` put together for the purposes of exploring practical schedules and defining the critical design, development and planning paths for the overall facility and its major sub-systems.

Atomic Physics Aspects of a Relativistic Nuclear Collider

Atomic Physics Aspects of a Relativistic Nuclear Collider

Date: November 1, 1984
Creator: Gould, R.
Description: Atomic collision cross sections involving bare uranium nuclei are large at relativistic energies and will affect the design and operation of a relativistic nuclear collider (RNC). The most significant may be production of electron-positron pairs and muon pairs ({approx} 10{sup 8} per sec. and 2000 per sec. respectively for a 100 GeV/nucleon collider with a luminosity of 10{sup 27} cm{sup 2} s{sup -1}). Although the pair production is a direct measure of the luminosity it is also a large source of background and capture of an electron from the pair by one of the nuclei will result in the loss of the ion. Another important loss mechanism is Coulomb excitation of the giant nuclear dipole and giant nuclear quadrupole resonances. Storing and colliding bare and highly-stripped uranium opens up new possibilities for novel atomic physics experiments and an alternate approach for present experiments. As examples, the use of a collider for experiments to study spontaneous decay of the super-critical state (both positron production and x-ray production) of quasi-atoms of atomic number Z > 172, and a storage-ring measurement of the ground state hyperfine structure of hydrogen like thallium as a test of quantum electrodynamics (QED) are discussed.

3-D computer simulations of EM field sin the APS vacuum chamber. Part 2: Time-domain analysis

3-D computer simulations of EM field sin the APS vacuum chamber. Part 2: Time-domain analysis

Date: January 20, 1989
Creator: Chou, W.
Description: Our simulations suggest that the strong peak around 4 GHz in the narrow gap observed in the measurements is generated by TE modes. Therefore, one should not worry about this peak insofar as the coupling impedance is concerned. On the other hand, some discrepancies between our simulations and the measurements are noticed and remain to be resolved.

Impedance studies: Part 1, A composition rule

Impedance studies: Part 1, A composition rule

Date: July 1, 1988
Creator: Chou, W. & Jin, Y.
Description: The impedances and the loss factors experienced by a particle beam that circulates in the APS storage ring play an essential role in the studies of the beam instability problem. Due to a large variety of structures in the ring, the computation of these parameters amounts to enormous work. During the last months, this was tackled numerically by invoking the MAFIA family, a set of codes developed mainly at DESY. The results are to be reported in several LS notes. This note is the first part and will discuss a composition rule that we observed in our calculations. The composition rule can be stated as follows. For a complicated structure, one may decompose it into simple components and compose these components to form new structures. Under certain conditions, the old and the new structures will give the same loss factors. This rule is in analogy to and an extension of the law of addition of resistances in sequence in the conventional circuit theory. We will discuss two examples to illustrate this rule.

Kinetic measurements on elementary fossil fuel combustion reactions over wide temperature ranges. Progress report, May 1, 1984--November 30, 1986

Date: December 1, 1986
Creator: Fontijn, A.; Mahmud, K. & Marshall, P.
Description: The HTP (high-temperature photochemistry technique) has been used to study the reactions of ground state 0 atoms with C{sub 2}H{sub 4}, C{sub 2}H{sub 2}, H{sub 2} and D{sub 2} over the 300 to 1500 K temperature range. The results are described and discussed, as are the plans for study of the 0 + 1,3 butadiene and C{sub 2}H{sub 6} reactions in the remainder of the present grant period.

Assessment of Critical Mass Laboratory safeguards and security upgrades

Assessment of Critical Mass Laboratory safeguards and security upgrades

Date: May 31, 1985
Creator: Merrill, B.J. & DeMyer, J.J.
Description: Pacific Northwest Laboratory (PNL) conducted an evaluation of the safeguards and security systems at the Critical Mass Laboratory (CML) in February 1985, to identify appropriate upgrading actions necessary to ensure that effective and efficient systems consistent with DOE-RL policies, procedures, and site priorities are in place. Since that evaluation, there have been changes in Patrol contingency philosophy, response tactics, and distribution of manpower. Because of these changes, and at the request of DOE-RL, PNL has re-evaluated the safeguards and security systems in place at CML.
