Inverse Rendering for PET Scanner Calibration

The significant degradation of reconstructed image resolution and the presence of apparent artifacts can result from sub-millimetric misalignment of scanner configuration in highspatial resolution positron emission tomography (PET) systems. Therefore, ensu ...

Impact of ICRF on the scrape-off layer and on plasma wall interactions: From present experiments to fusion reactor

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Yves Martin, Duccio Testa, Jonathan Graves, Henri Weisen, Dalziel Joseph Wilson, Yu Lin

Recent achievements in studies of the effects of ICRF (Ion Cyclotron Range of Frequencies) power on the SOL (Scrape-Off Layer) and PWI (Plasma Wall Interactions) in ASDEX Upgrade (AUG), Alcator C-Mod, and JET-ILW are reviewed. Capabilities to diagnose and ...

Physics and performance of the I-mode regime over an expanded operating space on Alcator C-Mod

Christian Gabriel Theiler, Yu Lin

New results on the I-mode regime of operation on the Alcator C-Mod tokamak are reported. This ELM-free regime features high energy confinement and a steep temperature pedestal, while particle confinement remains at L-mode levels, giving stationary density ...

Efficient generation of energetic ions in multi-ion plasmas by radio-frequency heating

Henri Weisen, Jonathan Marc Philippe Faustin, Yu Lin

We describe a new technique for the efficient generation of high-energy ions with electromagnetic ion cyclotron waves in multi-ion plasmas. The discussed three-ion scenarios are especially suited for strong wave absorption by a very low number of resonant ...

NAND-NOR: A Compact, Fast, and Delay Balanced FPGA Logic Element

Paolo Ienne, Grace Zgheib, Yu Lin, Wei Li

The And-Inverter Cone has been introduced as an alternative logic element to the look-up table in FPGAs, since it improves their performance and resource utilization. However, further analysis of the AIC design showed that it suffers from the delay discrep ...

A maximum-likelihood approach for building cell-type trees by lifting

Bernard Moret, Philipp Bucher, Yu Lin, Mingfu Shao, Nishanth Ulhas Nair, Paulina Grnarova, Laura Madeleine Hunter

Background: In cell differentiation, a less specialized cell differentiates into a more specialized one, even though all cells in one organism have (almost) the same genome. Epigenetic factors such as histone modifications are known to play a significant r ...

ADX: a high field, high power density, advanced divertor and RF tokamak

Christian Gabriel Theiler, Francesca Maria Poli, Yu Lin, John Wilson

The MIT Plasma Science and Fusion Center and collaborators are proposing a high-performance Advanced Divertor and RF tokamak eXperiment (ADX)-a tokamak specifically designed to address critical gaps in the world fusion research programme on the pathway to ...

Improved confinement in high-density H-modes via modification of the plasma boundary with lower hybrid waves

Christian Gabriel Theiler, Yu Lin, Peng Xu

Injecting Lower Hybrid Range of Frequency (LHRF) waves into Alcator C-Mod's high-density H-mode plasmas has led to enhanced global energy confinement by increasing pedestal temperature and pressure gradients, decreasing the separatrix density, modifying th ...
