Positive Evaluation for ADEX in the FP 7 MAX project

In News — July 31 2014

As part of the FP7 MAX (MYRRHA Accelerator eXperiment, research & development program) task 3.2, ADEX technology was the subject of a comparative evaluation, with respect to classical control techniques, for an experimental application at the 700 MHz cryogenic module in the instalations of the Institut de Physique Nucléare d’Orsay (IPNO), and in particular to its cold tuning system (CTS).

The CTS regulates the resonance frequency of the cavity under a range of operating conditions. Stable and precise control of the resonance frequency impacts directly on optimum cavity operation, in the minimization of energy consumption and on the total reliability of the installation.

The final report confirms that the ADEX system improved the stability and control precision of the CTS, and demonstrated its reliability in the presence of unforeseen and unknown perturbations where classical technology had lost control.

The knowledge acquired during the test campaign at Orsay demonstrated that both the design of the cryogenic module cavity, and the implementation of the control system, will benefit from the significant improvements likely to be gained in future research and development of the MAX project, but nevertheless, the results were highly satisfactory and demonstrated the validity of the applied technologies, and in particular that of ADEX.

El conocimiento adquirido durante la campaña de ensayos en Orsay pone en evidencia que, tanto el diseño de la cavidad del módulo criogénico como la implementación del sistema de control, serán objeto de importantes mejoras en los proyectos de I+D que seguirán al MAX, pero los resultados obtenidos son altamente satisfactorios y demuestran la validez de las tecnologías aplicadas y, en particular, de la tecnología ADEX.
