Heating of Cs2Te Photocathode via Field Emission and RF Pulsed Heating: Implication Toward Breakdown
Ryo Shinohara, Soumendu Bagchi, Evgenya Simakov +2
The occurrence of radio-frequency (rf) breakdown limits operational electromagnetic gradients in accelerator structures. Experimental evidence often suggests that breakdown events…
Data-Driven Modeling of Dislocation Mobility from Atomistics using Physics-Informed Machine Learning
Yifeng Tian, Soumendu Bagchi, Liam Myhill +5
Dislocation mobility, which dictates the response of dislocations to an applied stress, is a fundamental property of crystalline materials that governs the evolution of plastic def…
Anomalous entropy-driven kinetics of dislocation nucleation
Soumendu Bagchi, Danny Perez
The kinetics of dislocation reactions, such as dislocation multiplication, controls the plastic deformation in crystals beyond their elastic limit, therefore critical mechanisms in…
From anti-Arrhenius to Arrhenius behavior in a dislocation-obstacle bypass: Atomistic Simulations and Theoretical Investigation
Mohammadhossein Nahavandian, Soumit Sarkar, Soumendu Bagchi +2
Dislocations are the primary carriers of plasticity in metallic material. Understanding the basic mechanisms for dislocation movement is paramount to predicting the material mechan…
Formation of field-induced breakdown precursors on metallic electrode surfaces
Soumendu Bagchi, Evgenya Simakov, Danny Perez
Understanding the underlying factors responsible for higher-than-anticipated local field enhancements that trigger vacuum breakdown on pristine metal surfaces is crucial for the de…
Thermal and electric field driven breakdown precursor formation on metal surfaces
Ryo Shinohara, Soumendu Bagchi, Evgenya Simakov +2
The phenomenon of electric breakdown poses serious challenge to the design of devices that operate under high gradient environments. Experimental evidence often points towards brea…
