On Thursday, Dec. 5, at 11 a.m., Oleksandr Hryhorenko of Jefferson Lab will present "Downtime Sources in CEBAF SRF Linac Systems" in Test Lab rm. 1227 and via Zoom.
Abstract: In this talk, we will present some recent analysis of the reliability statistics of the CEBAF superconducting radiofrequency (SRF) linac systems. Downtime event statistics based on the two data sources, the Downtime Manager (DTM) and the Fast Shutdown System (FSD), were gathered and analyzed from 2017 to 2024, coinciding with CEBAF's 12 GeV era. We aim to pinpoint downtime sources for SRF linac sub-systems and components. The outcome of this effort may be useful for informing future SRF linac system maintenance to achieve its more reliable operation in CEBAF. Moreover, it might help to identify areas of SRF technology development needed by future high-power, high-reliability continuous-wave SRF linacs.
