It is considered that the maximum diameter of the horn should not exceed one-quarter of the wavelength [lambda] and the maximum cross section is denoted as [S.sub.m].

An interesting design aspect is represented by the value and position of the maximum cross section. Thus, we considered the condition that the first derivative of function (59) is equal to zero.

It can be concluded that the position of the maximum cross section is in the same place as the nodal point.

The parameters were adjusted from their original values as shows in table 3 (Hint: We select the energy at maximum cross section for different reactions for selected isotopes).

The radial distance is to be at most of the order of the r= 1:20fm and the energy of incident neutrons have been taken at maximum cross section. All parameters used in this work for optical model potential have been taken from (RIPL) library [12].

The maximum cross section deformation degree with mandrel diameter of 5.23 mm is more than 4.2%, while the maximum cross section deformation degree with mandrel diameter of 5.43 mm is less than 1.8%.

When the length is 0 mm, the maximum cross section deformation degree is 5.2%; when the length is 1 mm, the maximum cross section deformation degree is 3.8%; and when the length is 2 mm, the maximum cross section deformation degree is 1.8%.

Hollow conductor systems have declined in importance over recent years, largely because, for physical reasons, the treatment chambers are limited to a

maximum cross section of 50 x 50 mm, which severely limits the products which can be handled and because the maximum energy concentrations cause problems with overheating of the product.

Currently, extrusion of profiles with a

maximum cross section of 1" x 1" is possible.

The

maximum cross sections at two different center of mass energies of 1.5 TeV and 3 TeV were obtained to compare these processes between MSSM and 2HDM where several orders of magnitude difference was observed.
