Application of the Argonne Advanced Acceleration Test Facility to development for conventional accelerators (open access)

Application of the Argonne Advanced Acceleration Test Facility to development for conventional accelerators

The Argonne Advanced Acceleration Test Facility is designed as a powerful tool to test ideas for very high gradient acceleration schemes based on direct beam excitation of plasmas, metal structures, dielectrics, etc. The characteristic size in these systems is )approximately) 1 cm, corresponding to frequencies )approximately) 10 GHz. The question addressed here is whether the special features of this facility have application as well to the development of components for the more conventional, lower frequency, accelerators now operating or under development. It is suggested that the usefulness of the facility for the development of conventional systems could be enhanced by a provision for longer time delay between driver and witness beam pulses. 9 refs., 2 figs.

Design of a microwave calorimeter for the microwave tokamak experiment (open access)

Design of a microwave calorimeter for the microwave tokamak experiment

The initial design of a microwave calorimeter for the Microwave Tokamak Experiment is presented. The design is optimized to measure the refraction and absorption of millimeter rf microwaves as they traverse the toroidal plasma of the Alcator C tokamak. Techniques utilized can be adapted for use in measuring high intensity pulsed output from a microwave device in an environment of ultra high vacuum, intense fields of ionizing and non-ionizing radiation and intense magnetic fields. 16 refs.

Enzymatic desulfurization of coal (open access)

Enzymatic desulfurization of coal

Our current efforts to develop clean coal technology, emphasize the advantages of enzymatic desulfurization techniques and have specifically addressed the potential of using partially-purified extracellular microbial enzymes or commercially available enzymes. Our work is focused on the treatment of model'' organic sulfur compounds such as dibenzothiophene (DBT) and ethylphenylsulfide (EPS). Furthermore, we are designing experiments to facilitate the enzymatic process by means of a hydrated organic solvent matrix.

VII: VME/IORFI-II interface routines (open access)

VII: VME/IORFI-II interface routines

This document describes the VME/IORFI-II Interface routines (VII). These routines where designed to meet two needs. First, the routines enable programs written in PILS running on a MVME 101 under Valet-Plus to control an IORFI-II interface from VME. Secondly, the routines provide a high level language version of the FASTBUS standard routines for the IORFI-II which can easily be translated into other high level languages (like C). The routines fall into two general types, control and transaction. The control routines work directly with the interface registers. These routines set up and monitor operations between VME and the IORFI-II. The control routines are usually used indirectly by the programmer through the transaction routines. The transaction routines, such as VIIreverse arrowWRITEreverse arrowDAT, use the control routines to carry out complete functions on FASTBUS. Most FASTBUS operations have been implemented except for the compound routines and some low level routines. To facilitate access to the IORFI-II registers from VME, a Super-VIOR DMA board was used as a set of I/O registers tied to the IORFI-II's front panel connectors. The DMA controller on the Super-VIOR was not used and a much simpler board (only containing a set of four registers accessible from VME) could …

The use of the Fermilab antiproton Accumulator in medium energy physics experiments (open access)

The use of the Fermilab antiproton Accumulator in medium energy physics experiments

The Fermilab antiprotron Accumulator has been modified for use in a medium energy experiment. The experiment is conducted with circulating antiproton beam of momentum between 6.7 GeV/c and 3.7 GeV/c colliding with protons from an internal gas jet. Antiprotons are accumulated at the normal momentum of 8.9 GeV/c and then decelerated to the appropriate energy. It is necessary to cool the beam continually during the time it is colliding with the gas jet. The experiment requires new provisions for the control of magnet power supplies and low level rf system and modifications of the cooling system and high level energy systems to permit variable energy operation. Transition must be crossed to decelerate the beam below 5 GeV/c; because the deceleration is very slow, transition can not be crossed in a conventional manner. This paper will describe the required changes to the Accumulator and operating experience with protons. 8 refs., 2 figs., 1 tab.

Optimized multi-modal-operation designs for ITER (International Thermonuclear Experimental Reactor) (open access)

Optimized multi-modal-operation designs for ITER (International Thermonuclear Experimental Reactor)

The tokamak nonlinear optimization systems code TETRA has been expanded to contain the option of examining machine designs capable of ''multi-modal'' operations. The conceptual International Thermonuclear Experimental Reactor (ITER) is an example of a ''bi-modal'' operating machine design in that it must be capable of both pulse-ignited and steady-state operations. This new version of TETRA allows for the optimization of a ''figure-of-merit'' which may involve several operating scenarios. We obtain for ITER minimum cost designs which are capable of igniting when operated in the pulsed mode as well as have reasonable Q > 5 when operated in steady-state. 3 refs., 3 tabs.

Future opportunities for hadron spectroscopy at the MPS (open access)

Future opportunities for hadron spectroscopy at the MPS

Before I go into detailed MPS experiments, I will give a summary of the status of lattice gauge calculations of glueball masses plus glueball and hybrid masses from the bag model, and the flux tube model. For the following discussion, I am going to assume that multi-quark states or molecules are best described in terms of the MIT bag model of Jaffe with its spectrum best defined by work done by R.L. Jaffe and F.E. Low using a method called The P-Matrix. Using this method one sees that all 4-quark states will appear as very broad continuum like effects that one would not associate with meson resonances, except for the S* and the delta which forms a very special threshold K/bar K/ bound systems. There is a possibility that the E(1420) may also be related to the J/sup PC/ = 1/sup + +/, qq/bar q//bar q/ spectrum having its width narrowed by a final state interaction.
