استخدم 9Be(p,n)9 B في مسرع الـسيكلترون 9 السوري لحساب كثافة النترونات و الفوتونات الناتجة عن هذا التفاعل كتابع لسماكة هدف Be البيريليوم. استخدمت بروتونات مسرعة لطاقة 0MeV.15 ، و تيار شدته 0µA.200 .و درس أيضاً التوزع الـزاوي 9)n,p(9Be للنترونات الصادرة عن التفاعل B كتابع لسماكة الهدف، إذْ لوحظ أن القيمة العظمى للكثافـة 9B)n,p(9Be النترونية و الفوتونية تقع عند الزاوية صفر. قورنت القيم الحسابية بالنسبة إلى التفـاعلين و (n,p(Pb بالقيم التجربية بالنسبة إلى الطيف النترونات الصادر عن هذين التفاعلين، و وجد تطـابق 207 جيد بين القيم الحسابية و التجريبية.
The MCNPX and MCNP5C codes are used to simulate the reaction 9Be(p,n)9B. The photons and neutrons intensities resulting of this reaction are calculated as a functions of the 9Be target thickness. To calculate this intensity, the protons with energy 15.0MeV and protons current 200.0μA are used. In addition, the angular distribution of the emitted photons and neutrons from the reaction 9Be(p,n)9B is calculated as a function of the 9Be target thickness. The maximum value of the photons and neutrons flux is found to be at angle 00 for thin targets. The calculated values using MCNPX of the neutrons spectrum emission from reactions of 9Be(p,n)9B and 207Pb(p,n) is compared to experimental values. There is a good agreement between them.

The MCNPX and MCNP5-BETA codes were used to simulate the reaction
9Be(p,n)9B in the Syrian cyclotron,to calculate the neutron spectrum emission
from this reaction and for neutronic calculations to design of the thermal
neutron beam for thermal neutron radiography.
This papers reports the investigation of extensions of the group by means of the cyclic group A=<a> of order p, where p is a prime number.
It has been concluded from this work that, all non isomorphic extensions of
the group C(n) by means of the group A ,that correspond to irreducible
representations of the group A , are: - p Z
In this study, a simulation of the MTR-22MW reactor and a study
of standard and mixed fuel combustion using the Codes GETERA
and MCNP5.
The Results of the simulation showed that the operation time of the
reactor in the case of standard fuel is 274 days and if the use of
mixed fuel is 135 days.
The MCNP5-beta code was used to calculate the reaction rate and the neutron energy response matrix of a neutron spectrometry consisting of a Polyethylene sphere with variable diameter and BF3 detector, using point and disk neutron sources, the reacti
on rate and the response matrix of disk neutron source shows higher values than those obtained for point neutron source in addition the response with disk neutron source at the energy range shows a maximum value for sphere of 10 inch diameter where the response with point neutron source stile increasing in this condition .The results obtained in this work for the disk neutron source agreed well with published results.
The codes (EGSnrc, BEAMnrc) are used to simulate 6MV photon beam produced by
Varian ix linear accelerator and different field size (2020, 1010, 44cm2). The
simulation data is stored in a phase space file that contains complete details of the dat
es of
each particle by tracking its path and interactions.
Phase space files were analyzed using BEAMDP code to:
- Obtain energy spectrum, energy flow, distribution of the mean energy and the
angular distribution of the photons and contaminant electrons on surface of water phantom
and 100cm away from linear accelerator head.
- Study effect of field size on distribution of the energy spectrum 6MV.
- Study of change in distribution of mean energy between center and edge of the field
size.
- Calculation the contribution of contaminant electrons within photonic beam at
21%.
