The accessibility of future combination gadgets, for example, a Fusion Nuclear Science Facility incredibly relies upon long working lifetimes of plasma confronting segments in their diverters. Material-Plasma Exposure will use another high-force plasma source idea dependent RF innovation. This spring idea permit test to swathe the whole ordinary plasma surroundings in the diverter of a hope combination reactor. The option to examine disintegration and re-affidavit for pertinent calculations with applicable thrilling and attractive fields before the objective. Material-Plasma Exposure is being intended to take into consideration the presentation of from the earlier neutron-lighted examples. The objective exchange container has been intended to straight plasma generator with the end goal that it very well may be moved to posting for more itemized surface examination. Material-Plasma Exposure is being created in an arranged methodology with progressively expanded abilities. After the underlying improvement stride of the helicon source and the source idea is being tried in the Proto-Material-Plasma Exposure gadget. First warming with microwaves brought about a superior ionization spoke to by privileged electron solidity on pivot, when contrasted with the helicon plasma just without warming.

We have numerically studied how an actual confinement magnetostatic field affects power deposition in a helicon source. We have solved the wave propagation by means of two electromagnetic solvers, namely: (i) plaSma Padova Inhomogeneous Radial Electromagnetic solver (SPIREs), a mono-dimensional finite-difference frequency-domain code, and (ii) Advanced coDe for Anisotropic Media and ANTennas (ADAMANT), a full-wave three-dimensional tool based on the method of moments. We have computed the deposited power spectrum with SPIREs, power deposition profile with ADAMANT and the antenna impedance with both codes. First we have verified the numerical accuracy of both SPIREs and ADAMNT. Then, we have analysed two configurations of magnetostatic field, namely produced by Maxwell coils, and Helmholtz coils. For each configuration we have studied three cases: (i) low density $n=10^{17}~\text{m}^{-3}$ and low magnetic field $B_{0}=250$  G; (ii) medium density $n=10^{18}~\text{m}^{-3}$ and medium magnetic field $B_{0}=500$  G; (iii) high density $n=10^{19}~\text{m}^{-3}$ and high magnetic field $B_{0}=1000$  G. We have found that the Maxwell coil configuration does not produces significant changes in the deposited power phenomenon with respect to a perfectly uniform and axial magnetostatic field. While the Helmholtz coil configuration can lead to a power spectrum peaked near the axis of the discharge.
