Technology Assessment for an Electromagnetic Radiation Dosimetry Temperature Probe Interface

Measuring temperature in specimens being heated by electromagnetic energy requires the use of special probes. The temperature probes must be specially designed to minimize electromagnetic field perturbations. The probes in widespread usage in research institutes are thermistor sensors with very high resistance leads. This are very similar to those described by R.R. Bowman (IEEE Trans. Microwave Theory Tech MTT 24:43-45, 1976). Although the probes are commercially available, an interface is required to standard laboratory computers. This study determines the feasibility and assesses the current technology for developing an interface between the non-perturbing temperature probes and a IBM PC compatible computer using commercially available components. At the completion of this study at least one preliminary design will be presented for development.
