Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

Two reference operational scenarios for the ITER CDA design are examined with the time-dependent 1½-D WHIST transport code: the A1 ignition case and the B1 long-pulse case. Plasma profiles are evaluated self-consistently from the source profiles and radial-dependent transport properties. Among the time-dependent issues addressed are the time scales for startup and shutdown as determined by current profile relaxation rates (skin times), fueling and particle pumping rates, and auxiliary heating and current drive sources. Operational constraints are monitored throughout the simulations: βt, ℓi, , ne(a), etc.
