It is found that the optimum gap distance between the anode and the cathode is equal to 3.5 mm, where stable discharge current and maximum output ion beam current can be obtained.
Although the argon content increases with increasing Ar fraction in the ion beam to a maximum value of approximately 2%, it can be concluded that Ar yields a major stress contribution.
In the heating test, the mock-up was exposed to repetitive hydrogen ion beam irradiation with the maximum heat flux of 0.5 MW/m2.
On the other hand, when the height of the entering ion beam is 0.4 mm, the maximum intensity is 44, the corresponding peak position is 6.95, the half peak positions are -7.09722 and -6.70556, and the resolution is 6.95/ 7.09722-6.70556)=17.7.
A monoenergetic ion beam with a full-width/half-maximum (FWHM) of 5 mm is extracted from the accelerator system (synchrotron) and magnetically deflected to subsequently scan all planned iso-energetic slices roughly corresponding to the tumour's radiological depth.

Finally, an optimum concentration of 20 40% [H2]/[H2+N2] ion beam composition was determined to obtain maximum nitrogen incorporation on the metal surface.
For (a) pristine and (b) irradiated film with a maximum magnetic field of 20 kOe applied parallel and perpendicular to ion beam direction.
The energy for each ion beam was set in order to reach a maximum penetration in ICRU tissue of 290 mm (equivalent to the therapeutic range of 430 MeV/amu carbon ions).
