Ion related problems for the XLS ring (open access)

Ion related problems for the XLS ring

The electron beam in the XLS will collide with the residual gas in the vacuum chamber. The positive ions will be trapped in the potential well of the electron beam. They will perform stable or unstable oscillations around the beam under the repetitive Coulomb force of the bunches. If not cleared, the captured ions will lead to partial or total neutralization of the beam, causing both, a decrease of life-time and a change in the vertical tunes as well as an increase in the tune-spread. They can also cause coherent transverse instabilities. The degree of neutralization {theta} that one can tolerate, is primarily determined by the allowable tune shift, which of the XLS is between 1 and 5 10{sup {minus}3}. Electrostatic clearing electrodes will be used to keep the neutralization below the desired limit. In order to determine their location and the necessary clearing-rate and voltage, we examine the ion production rate, longitudinal velocity of ions in field-free regions and in the dipoles to see what distance the ions can travel without clearing before the neutralization of the beam reaches the prescribed limit, beam potential to see the locations of the potential wells, voltage requirements for ion clearing, critical mass …

A new semicustom integrated bipolar amplifier for silicon strip detectors (open access)

A new semicustom integrated bipolar amplifier for silicon strip detectors

The QPA02 is a four channel DC coupled two stage transimpedance amplifier designed at Fermilab on a semicustom linear array (Quickchip 2S) manufactured by Tektronix. The chip was developed as a silicon strip amplifier but may have other applications as well. Each channel consists of a preamplifier and a second stage amplifier/sharper with differential output which can directly drive a transmission line (90 to 140 ohms). External bypass capacitors are the only discrete components required. QPA02 has been tested and demonstrated to be an effective silicon strip amplifier. Other applications may exist which can use this amplifier or a modified version of this amplifier. For example, another design is now in progress for a wire chamber amplifier, QPA03, to be reported later. Only a relatively small effort was required to modify the design and layout for this application. 11 figs.

Design wind speeds for high hazard, moderate hazard, important/low hazard and general use facilities at the Savannah River Site (open access)

Design wind speeds for high hazard, moderate hazard, important/low hazard and general use facilities at the Savannah River Site

The design wind speeds for High Hazard, Moderate Hazard, Important/Low Hazard and General Use facilities at the Savannah River Site are developed below using the procedures and site-specific hazards model required by DOE Order 6430.1A. These are less than the previously required Design Wind Speeds and are: (1) High Hazard (Maximum Resistance) Facility, 185 mph; (2) Moderate Hazard (High Resistance) Facility, 37 mph; (3) Important/Low Hazard (Intermediate) Facility, 83 mph; and, (4) General Use (Standard) Facility, 78 mph.

The USC macro data-flow simulator. Technical report (open access)

The USC macro data-flow simulator. Technical report

As device technology develops to the limit of speed of light, parallel processing comes into play for high performance calculation. Conventional von Neumann computation show difficulty because of its single threadness. Many hybrid models have been proposed; they are reviewed, leading to the macro data-flow model. This macro data-flow is a scheme having a multilevel of model of execution which higher model is a tagged data-flow and lower level is von Neumann. Partitioning should be carefully done. A simple simulator has been developed, executing a macro data-flow graph. Micro instructions within a macro actor can access and process those vector data from higher data-flow level. Architectural description of this simulator and some special actors supporting this hybrid model are discussed. Details of instructions are explained as user reference manual, including sample programs and statistic gathering methods. In addition to the hardware simulator, a graph simulator was developed for simple execution of data-flow graph without resource limit of hardware details.

Checkout and start-up of the integrated DWPF (Defense Waste Processing Facility) melter system (open access)

Checkout and start-up of the integrated DWPF (Defense Waste Processing Facility) melter system

The Integrated DWPF Melter System (IDMS) is a one-ninth-scale demonstration of the Defense Waste Processing Facility (DWPF) feed preparation, melter, and off-gas systems. The IDMS will be the first engineering-scale melter system at SRL to process mercury and flowsheet levels of halides and sulfates. This report includes a summary of the IDMS program objectives, system and equipment descriptions, and detailed discussions of the system checkout and start-up. 10 refs., 44 figs., 20 tabs.

Exhaust Fan Temperature Switch (open access)

Exhaust Fan Temperature Switch

The 13000 cfm 'emergency' vent fan must be protected from over cooling which would result in a mechanical failure. Over cooling could result from a catastrophic cryogen release from the cryostat(s) or Argon Storage Dewar. In order to protect the fan, a VPT has been calibrated for -31 C to open a switch which sends a signal to allow warm gas to enter the sump by means of a motor controlled louver installed at 'sidewalk level' in the ductwork between the assembly hall and the Argon Dewar Enclosure. The bulb of the VPT is enclosed in a thermal well and will be placed in the gas stream directly above the fan. The switching unit will be mounted nearby on the wall in order to isolate it from vibrational effects. Should the fan be activated due to a cryogen release, it should not experience any problems when operating above -40 C. The switch was set and checked in a saturated calcium chloride solution cooled to -31 C by running cold gaseous Nitrogen through a copper tube coiled in a dewar. Switching temperature was measured by a thermocouple tied to the VPT bulb. The thermocouple was checked in LN2, in an ice …
