Water phantom explorer regulated by computer

Abstract

A water phantom device is meant to work directly with a Hewlett-Packard 9825 T small computer. The purpose of this work is to read the distribution of absorbed dose released into a perspex container of water with the help of a semiconductor detector which can move in the three dimensions of space. Above the container a second detector situated on the edge of the beam is used as a monitor. The execution of the programmes written in HPL (Hewlett-Packard Language) offers the possibility either to carry out a preprogrammed cycle of displacements and measures or to work in interacting mode. The collected measures (space, co-ordinates and dose measures) are visualized by a plotter and recorded on a cassette tape. The signals delivered by the detectors are amplified separately then a dividing circuit delivers a tension in proportion with the ratio of these two signals. This tension is independent of the dose rate fluctuations of the irradiation beam and can be read by the computer. The examples of study of photon and electron beams that are described hereafter are meant to show the interest of a command that can be programmed.
