Results of radiation shielding calculations performed for extraction beam absorbers of a Fermilab photoinjector with the MARS14 code are presented. They can be used in other similar projects, particularly early sections of linear colliders.

As a part of the ongoing Booster improvement project, all the available data on booster magnets are collected and tabulated. Data include not only the survey results available at present (July 2003) but the magnet moves as well. The main purpose of this exercise is not to provide a basis for the future magnet moves. Rather, the goal is to present the present knowledge on where magnets are and incorporate it into, for example, the MAD lattice file so that one can see the impact of misaligned magnets on the closed orbit in the absence of any corrections.

This report discusses issues debated in the 107th Congress while is considering various proposals to amend the Endangered Species Act of 1973 (ESA). Major issues in recent years have included changing the role of science in decision-making, changing the role of critical habitat, reducing conflicts with Department of Defense activities, incorporating further protection for property owners, and increasing protection of listed species, among others. In addition, many have advocated including significant changes to ESA regulations made during the Clinton Administration in the law itself.
