The Ratio of the Direct Photon
نویسنده
چکیده
We measure the ratio of the isolated direct photon prodution cross section at p s = 630 GeV to that at p s = 1800 GeV for the central (jj < 0:9) and forward (1:6 < jj < 2:5) rapidity regions. We compare the result with next to leading order QCD predictions using CTEQ parton distribution functions.

روشی برای شبیه سازی ترابرد فوتون درماده
Monte Carlo simulation is widely used in calculations involing transport of photons through different materials of different shapes. The method consists of randomly generating a finite set of photon histories over which the quantities of interest are averaged. In photon transport calculations, sampling the photon scattering angle from the Klein-Nishina probability distribution is of special i...
متن کاملEvaluation of the Effects of Different Filters and Helium Bag on the Reduction of Electron Contamination in Photon Beam of Neptun Linac
Introduction: Skin sparing is one of the most desirable characteristics of high energy photon beams. However, the photons emerging from the target of linacs are contaminated by secondary electrons as a result of their interactions with air, collimators, flattening filter and any other objects in their path. This phenomenon tends to increase the skin dose received b...
متن کاملImpact of Silicone gel breast prosthesis on photon beam therapy of recurrence carcinoma post mastectomy
AbstractIntroduction Silicone gel breast implants are used for breast reconstruction post mastectomy. In the event of cancer recurrence, the radiation oncologists are forced to irradiate through the prosthesis device. Due to prosthesis higher atomic number dose perturbations occur during treatment. This study determined the influence of silicone gel thickness on the photon beam distribution. Ma...
متن کاملStudy of Radiation Dose Enhancement to Capillary Endothelial Cells Due to the Presence of Heavy Metal Nanoparticles in Two Cell and Tumor Scales by Monte Carlo Method
Introduction: Recently, the use of various sensitizers has been used to increase photon-induced doses in brachytherapy. One of these cases is the addition of heavy metal nanoparticles such as gold in the target area, which increases the production of ionizing electrons by increasing the possibility of photoelectric effects, and increases the efficacy of the treatment. In this study, the target ...
متن کاملEffective Point of Measurement in Cylindrical Ion Chamber for Megavoltage Photon Beams
Introduction For dose measurement in Megavoltage (MV) photon beams with ion chambers, the effect of volume occupied by the air cavity is not negligible. Therefore, the result of measurement should be corrected with a displacement perturbation correction factor (Pdis) or using an effective point of measurement (EPOM). The aim of this study is to calculate the EPOM for cylindrical ion chamber and...
