SUMMARY:Science Basis and Present Status of the new Divertor Tokamak T
 est facility\, Plasma Physics (Physics/ECE/NE 922) Seminar\, Piero Mar
 tin\, University of Padova and Consorzio RFX\, Padova\, Italy\; DTT Co
 nsortium\, Frascati\, Italy
DESCRIPTION:One of the high priority challenges for the exploitation o
 f fusion as an energy source is the disposal of the non-neutronic ener
 gy and particle exhaust in a reactor. The new Divertor Tokamak Test (D
 TT) facility (its construction is starting in Italy) [1]\, is an exper
 iment to address that challenge in high-field\, high performance tokam
 ak with full integration between core and edge plasma scenarios.<br>

\nDTT is superconducting tokamak with 6 T on-axis maximum toroi
 dal magnetic field carrying plasma current up to 5.5 MA in pulses with
  length up to 100s. The D-shaped device is up-down symmetric\, with ma
 jor radius R=2.19 m and minor radius a=0.70 m. The auxiliary heating p
 ower coupled to the plasma at maximum performance is 45 MW\, shared be
 tween 170 GHz ECRH\, 60-90 MHz ICRH and 500 kV negative ion beam injec
 tors. This allows matching the PSEP/R values\, where Psep is the power
  flowing through the last closed magnetic surface\, with those of ITER
  and DEMO. DTT is in fact designed to reach PSEP/R =15 MW/m. <br>

\nThis talk will discuss the science basis for the experiment and 
 the state of the art of the project. The presentation will start from 
 the scientific background of the experiment\,  then will move to its m
 ain physics driver and finally will discuss the expected plasma scenar
 ios - in particular as far as plasma exhaust is concerned. Emphasis wi
 ll be given to highlight the effort of designing an experimental tool\
 , which will be a device not only for plasma exhaust studies\, but als
 o for the advancement of fusion science in the grand sense.<br>
