Calibration method used for measurements with an open PEA set-up
Résumé
Abstract New systems based on the Pulsed Electro Acoustic (PEA) method (Short Circuit, Open PEA set-up) to study space charge distribution in electron irradiated materials have been developed in the last past few years. In any cases, once a signal is obtained it is necessary to ensure the reproducibility of the measurements. It is also important to develop appropriated data numerical treatments to obtain quantitative results. To do so a reference signal is required. As the calibration protocol adopted in the case of the classical PEA method could not be used any more, a new one has been proposed and tested. This paper deals with the description and validation of the procedure used to record a proper reference signal to treat raw data obtained with the ‘Open PEA’ set-up. Results recorded under various conditions will be compared.
