Development of a Data Aquisition System at a Nuclear Microprobe with Applications in the Geo- and Biosciences

Elfman, Mikael LU (2001)
Abstract
This thesis is divided in two parts, one that deals with the development of the new data acquisition system at Lund Nuclear Microprobe, and a second part that deals with different applications. A CAMAC based data acquisition system has been installed at the Lund Nuclear Microprobe facility. The system is a true multi-parameter and multi-detector system with fast FERA bus readout and in crate memory buffer. Each event in a detector produces a gate to all of the multiple parameters that should be acquired in coincidence. The system reads and tags each event and scaler word with X-Y position. The charge is measured by a current digitiser connected to a scaler. The beam scanning part is software controlled through a Timed D/A converter, this... (More)

Each event in a detector produces a gate to all of the multiple parameters that should be acquired in coincidence. The system reads and tags each event and scaler word with X-Y position. The charge is measured by a current digitiser connected to a scaler. The beam scanning part is software controlled through a Timed D/A converter, this allows for fast scanning of the beam, this unit generates the coordinates. The work with the development of this system is described. Applications in various fields are discussed: Otolith analyses and micro fossil analyses. To know a fish life history (or the age of the fish) is an important factor in assessment of fish populations. Otolith growth is a combination of seasonal and daily increments combined with random events. The otolith develops in rings from its center (incremental zone), a tiny ring presents when the fish hatches. The Sr level in this point is transferred from the mother. The analyses of otoliths from Salmo trutta and Anguilla anguilla are reported. (Less)
