Overview of IFMIF-DONES diagnostics: Requirements and techniques

Abstract

The IFMIF-DONES Facility is a unique first-class scientific infrastructure whose construction is foreseen

in Granada, Spain, in the coming years. Strong integration efforts are being made at the current project

phase aiming at harmonizing the ongoing design of the different and complex Systems of the facility. The

consolidation of the Diagnostics and Instrumentation, transversal across many of them, is a key element of

this purpose. A top-down strategy is proposed for a systematic Diagnostics Review and Requirement definition,

putting emphasis in the one-of-a-kind instruments necessary by the operational particularities of some of the

Systems, as well as to the harsh environment that they shall survive. In addition, other transversal aspects

such as the ones related to Safety and Machine Protection and their respective requirements shall be also

considered. The goal is therefore to advance further and solidly in the respective designs, identify problems in

advance, and steer the Diagnostics development and validation campaigns that will be required. The present

work provides an overview of this integration strategy as well as a description of some of the most challenging

Diagnostics and Instruments within the facility, including several proposed techniques currently under study.
