VORP, an improved detector system for remote measurements. [Voltage Output Radiation Probe for ionization chamber readout for underground nuclear explosion diagnostics]

Description: The Voltage Output Radiation Probe (VORP) is used as the detector to monitor radiological data on underground nuclear tests at the Department of Energy (DOE) Nevada Test Site. The VORP was designed to convert the current output of a Neher-White ionization chamber to a voltage output. There are several advantages in having a voltage output device rather than a low current probe in the field. The VORP makes it easier to protect against transients induced in the field wires. It also allows the use… more

Notes on the fast bus system

Description: In any system there will be modules that gather and process data from the experiment's detectors and perhaps from other sources such as the accelerator control system or monitoring system. In order to have a general system these modules must be able to communicate with each other and perhaps with a host computer or a group of controlling computers. A very general communications system is the bus system, used in computers, in which all devices are connected in parallel to a group of lines, typic… more

DOE-furnished data acquisition system installation, operation and maintenance. Final technical report

Description: Although the DOE-furnished data acquisition was not fully automated and bugs remained in the program, the system was operated and the data were compared with that obtained by Paraho data processing. On-stream analyses were not operational during the computer operation. The Hewlett-Packard (HP) gas chromatograph had provided valid data earlier. Maintenance and repairs of subsequent malfunctions by DEI, HP, and LETC personnel failed to provide valid on-stream GC analyses. The software program and… more
