About

F. Penzel is a plasma diagnostics specialist whose work focuses on the precise measurement and calibration of bolometer systems for fusion energy devices, particularly ITER and ASDEX Upgrade. Their key research areas include optical collimator design, automated in-situ calibration techniques, and geometrical property measurement for fusion diagnostics. Penzel’s most significant contribution is the development of an automated method for in situ measurement of bolometer collimator geometries, which enables accurate line-of-sight characterization without requiring device disassembly—a critical capability for maintaining diagnostic performance in reactor-relevant conditions. Their 2013 study on ITER bolometer prototype collimators (10 citations) established foundational methods for assessing collimator line-of-sight characteristics, while subsequent work on ASDEX Upgrade (3 citations) demonstrated the practical application of automated calibration in an operating tokamak. Though citation counts are modest, Penzel’s work addresses a crucial engineering challenge in fusion diagnostics: ensuring that bolometer measurements remain reliable over long operational campaigns. Their automated calibration approach reduces maintenance downtime and improves data quality, directly supporting the development of robust diagnostic systems for next-generation fusion devices like ITER.
