ANALOG FRONT-END ELECTRONICS FOR BEAM POSITION MEASUREMENT ON THE BEAM HALO MEASUREMENT
Enhancements have been made to the log-ratio analog front-end electronics based on the Analog Devices 8307 logarithmic amplifier as used on the LEDA accelerator. The dynamic range of greater than 85 dB, has been extended to nearly the full capability of the AD8307 from the previous design of approximately 65 dB through the addition of a 350 MHz band-pass filter, careful use of ground and power plane placement, signal routing, and power supply bypassing. Additionally, selection of high-isolation RF switches (55dB) has been an integral part of a new calibration technique, which is fully described in another paper submitted to this conference. Provision has also been made for insertion of a first-stage low-noise amplifier for using the circuit under low-signal conditions.

Analysis of cook-off using logic models
Developing a predictive model for cook-off is a difficult task. Recent experiments with PBX 9501 have shown that under certain heating and confinement conditions it is possible to generate large regions of almost uniform temperature in an explosive. Such regions react violently in a coherent fashion and may have the potential to produce unusually symmetric detonation waves in certain geometries. These results were unexpected before the experiments and have generated considerable additional activity both experimentally and in model building. At this time, there is no unambiguous explanation for the observed behavior, and therefore, there is a considerable number of fledgling models in existence. These models suggest varying and possibly contradictory mechanisms to explain the thermal profiles and wave behavior data. In this paper, we present an approach to model development for cook-off of PBX 9501 based on logic models called process trees. Process trees are well-suited to the task of describing causal sequences and delineating alternative descriptions of observed phenomenology. Therefore, they provide a valuable basis for constructing physical models and integrating them.

ANALYSIS OF THE SECOND ZEUS CRITICAL EXPERIMENT
The Zeus experiments have been designed to test the adequacy of {sup 235}U cross sections in the intermediate energy range. The first Zeus experiment achieved initial criticality on April 26, 1999 with 10 HEU platters and 79 platters of graphite. The second experiment reached a critical condition on October 24, 2000, with 9 HEU platters and 54 platters of graphite. The first experiment, which has been described and analyzed previously, had a C/{sup 235}U ratio of approximately 52:1. The corresponding ratio for the second experiment was approximately 40:1. This summary describes the analysis of the second Zeus critical experiment.

Analysis of the slot heating of the Coupled Cavity Linac cavity.
CCL cavities are figures of revolution about the beam axis. An automated tuning program sets up the geometry for a symmetric accelerating cavity and runs SUPERFISH repetitively, varying the geometry to tune each cavity to the desired frequency for the electromagnetic fields. SUPERFISH solves Maxwell's equations in 2-D. A large portion of the RF power (60-80%) applied to accelerate protons is a waste heat deposited on the inside of the copper cavity. This waste heat is removed most efficiently with water circulating through cooling passages. The waste heat needs to be removed in order to minimize thermal deformations and with it control the resonance of the cavities. A slot between the main cavity and coupled cavity receives additional heating that is not captured in the 2-D analysis. This heating causes deformation of the region and with it frequency shift. This paper covers the estimation of the slot heating and three-dimensional thermal and structural analysis of the CCL cavity.

Recording of Rajmil Fischman's And I think to myself.... This is a work for electronics that was inspired by the song "What a Wonderful World". The idea of the piece comes from the idea of taking a virtual "stroll" through a utopia described by Plato in his book, The Republic. There are three central movements that correspond to the realization of wisdom, courage, and temperance.

ANFO cylinder tests
Cylinder test data is reported for commercially available prilled ANFO (ammonium-nitrate/fuel-oil) at 0.93 ,g/cc density and ambient temperature. The tests were four-inch inner diameter, with wall-thickness and length scaled from the standard one-inch test (0.4 inch and 48 inch, respectively). The wall expansion was measured with a rotating mirror streak camera and the velocity was measured by fine-wire pin switches, in the standard manner. The wall expansion trajectory is much smoother than for conventional explosives, which show a pronounced jump-off with subs uent ring-up. This observation is consistent with a broadened detohation shock in the granular bed. ?he data is analyzed for equation-of-state information and JWL parameters are given.
