Remote manipulator experience in target train maintenance at Fermilab (open access)

Remote manipulator experience in target train maintenance at Fermilab

When Fermilab was designed in the late 1960's and early 1970's, it was anticipated that Neutrino target train servicing could be costly in terms of personnel radiation exposure. This was based in part on the expectation that target intensities of at least 1E13 protons/pulse would be required to produce several neutrino interactions in a large bubble chamber detector. This was indeed later proven to be the case and historically the Neutrino beamline has been targeted with about one half of the protons available from the Main Ring. It was believed that much of the occupational radiation dose from the Neutrino Area could be spared by utilization of a remote manipulator system, which was eventually installed. It is the purpose of this report to examine the use of the Fermilab remote manipulator system and evaluate its cost effectiveness and success as an ALARA (As Low As Reasonably Achievable) tool. 16 references, 11 figures.

Modification of the code BEAMCORR, and some simulation results of the magnet and achromat misalignments for the SLC South Arc (open access)

Modification of the code BEAMCORR, and some simulation results of the magnet and achromat misalignments for the SLC South Arc

An important decision has been made regarding the correction scheme for the arcs leading to the adoption of the so called scheme I. In this scheme the beam position data are collected from single-plane x and y Beam Position Monitors (BPMs), which are placed in the drift spaces adjacent to the downstream D- and F-magnets correspondingly. Similarly, single-plane x and y correctors are used for moving the upstream end of the corresponding magnets. In the present simulation this scheme is used exclusively. The first order calculations performed by means of TRANSPORT appear to be unsatisfactory from the point of view of the beam spotsize at the interaction point (IP). In this note we describe the modification to our program BEAMCORR which employs second order calculations by means of the program TURTLE. We also present the results of the following simulations: (a) study of the effects of two different levels of magnet misalignment on the beam spotsize at IP, and comparison of the results with those obtained by means of the program DINGBAT; (b) study of disjoints between achromats (both the displacement of the adjacent ends and angular discontinuity between achromats).

Preliminary experiments with a carbon fiber tuft cathode (open access)

Preliminary experiments with a carbon fiber tuft cathode

This work reports initial tests of a carbon brush or tuft cathode intended for use by the Beam Research Program. It was found that electric fields of approximately 100 kV/cm were required to produce current densities above 20 A/sq cm. The beam extracted from the cathode consisted of many beamlets - one for each tuft. The beamlets were found to be quite uniform in peak current density and the cathode operation was microscopically repeatable. The turn-on time was estimated to be 200 ns.

Utility Monitoring for the Antiproton Source (open access)

Utility Monitoring for the Antiproton Source

The purpose of the utility portion of the FIRUS system is to alert humans in the main control room, at Phillips farm, and in building 10 control room when either environmental conditions are unhealthy for antiproton source devices, or electrical or mechanical equipment is malfunctioning. When first envisioned, the FIRUS system consisted of the following equipment: (1) 2 FIRUS mini-computers (wall mounted, 1 fire, 1 utility); (2) emergency power supply (also wall mounted); (3) coax hardline communication cable; (4) Junction boxes; (5) contact points and analog transducers; (6) three-pair 18 gage shielded cable; and (7) silent printer. Each mini can monitor 16 contact points or 15 analog points or a combination of contact and analog points. Each contact point can be more than one physical point if the points are wired in series. An alarm then indicates anyone of a group of points has opened. The following devices/quantities are proposed to be monitored by the utility portion of the FIRUS system: (1) sump pumps; (2) LCW (Low Conductivity Water); (3) auxiliary generator; (4) service building temperatures; (5) stub room/tunnel temperature; and (6) stub room/tunnel humidity. After the number of quantities to be monitored (see table I) was determined, it was …

Impact assessment of additional safeguards and security controls on selected nuclides (open access)

Impact assessment of additional safeguards and security controls on selected nuclides

Battelle, Pacific Northwest Laboratory (PNL) has reviewed the current and projected inventory quantities of the selected nuclides in the reference letter and completed a quick assessment of the impacts of the additional safeguards and security controls. The areas that will be impacted are; physical protection, measurement systems, manual revisions, computer systems, and training.

The American Telephone and Telegraph Divestiture: Background, Provisions, and Restructuring (open access)

The American Telephone and Telegraph Divestiture: Background, Provisions, and Restructuring

On January 1, 1984, The American Telephone and Telegraph Company (AT&T) divested itself of a major portion of its organizational structure and functions. Under the post-divestiture environment the once fully-integrated Bell System is now reorganized into the "new" AT&T and seven Ladependent regional holding companies -- American Information Technologies Corp., 3ell Atlantic Corp., 3ell- South Corp., NYNEX Corp., Pacific Telesis Group., Southwestern Bell Corp., and U.S. West, Inc. The following analysis provides an overview of the pre- and post-divestiture organizational structure and details the evolution of the antitrust action which resulted in this divestiture.
