CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe present an overview of the FTU experimental results related to two important ITER physics issues concerning the mitigation of runaway electrons (RE): the measurement of the threshold electric field for RE generation and the position control and ramp-down of disruption-generated RE. A strong experimental program devoted to RE studies has been recently enabled in FTU by the integration of diagnostic, hardware and software tools in the real-time (RT) plasma control system. Several diagnostics are (being) upgraded to RT operation: the hard x-ray (HXR) radial profile monitor measuring in-plasma bremsstrahlung from RE, a set of Mirnov coils used for disruption prediction algorithms, the CO2 scanning interferometer for RE position control, a fission chamber monitoring the gamma-ray emission as a signature of RE interactions with the plasma facing components (PFC). In addition, a Cherenkov probe was installed to study the RE dynamics in presence of magnetic islands [1] and a RE imaging system (REIS) is being tested to detect visible/infrared synchrotron radiation emitted by RE.
