The evolution of the scrape-off layer (SOL) during a disruption in the DIII-D tokamak is modeled using the 2-D UEDGE transport code. The focus is on the thermal quench phase when most of the energy content of the discharge is rapidly transported across the magnetic separatrix where it then flows to material surfaces or is radiated. Comparisons between the simulation and an experiment on the DIII-D tokamak are made with the heat flux to the divertor plate, and temperature and density profiles at the SOL midplane. The temporal response of the separate electron and ion heat-flux components to the divertor plate is calculated. The sensitivity of the solution to assumptions of electron heat-flux models and impurity radiation is investigated.

Video footage from The Black Academy of Arts and Letters recorded during the "Center of my Joy" concert featuring Richard Smallwood and the Smallwood singers along with Vision Choral Ensemble. The concert was held on March 16th, 1996 at the Naomi Brution Theatre. The footage shows large choirs in robes singing together with various featured female soloists singing praise and worship music.
