First principle-based multi-channel integrated modelling in support of the design of the Divertor Tokamak Test facility

An intensive integrated modelling work of the main scenarios of the new Divertor Tokamak Test (DTT) facility with a single null divertor configuration has been performed using first principle quasi-linear transport models, in support of the design of the device and of the definition of its scientific work programme. First results of this integrated modelling work on DTT (R (0) = 2.14 m, a = 0.65 m) are presented here along with outcome of the gyrokinetic simulations used to validate the reduced models in the DTT range of parameters. As a result of this work, the heating mix has been defined, the size of device has been increased to R (0) = 2.19 m and a = 0.70 m, the use of pellets for fuelling has been recommended and reference profiles for diagnostic design, estimates of neutron yields and fast particle losses have been made available.

Automated summary

An intensive integrated modeling work was conducted to support the design and scientific work program of the new Divertor Tokamak Test (DTT) facility. Through this work, heating mix, device size, and fueling recommendations were defined, along with reference profiles for diagnostic design, estimates of neutron yields, and fast particle losses.
