The results of theoretical and numerical considerations of linear Compton scattering are used to evaluate characteristics of X-rays produced by collision between a low emittance electron beam and intensive laser light in an X-ray generator NESTOR of NSC KIPT. Two main generation modes have been under consideration at preliminary NESTOR design. There are the operation mode for medicine 33.4 keV ...

The Lawrence Berkeley National Laboratory (LBNL) is designing and building the 2.5 MeV front end injector for the Spallation Neutron Source (SNS) [1,2]. This injector comprises an H ion source, a low energy beam transport line (LEBT), a radio-frequency quadrupole (RFQ) and a beam transport line designed to provide fast chopping of the beam. The RFQ is designed to accelerate the H beam from the ...

Introduction Use of hadron therapy as an advanced radiotherapy technique is increasing. In this method, secondary particles are produced through primary beam interactions with the beam-transport system and the patient’s body. In this study, Monte Carlo simulations were employed to determine the dose of produced secondary particles, particularly neutrons during treatment. Materials and Methods I...

The Radioactive Beam Experiment (REX-ISOLDE) [1,2] is a pilot experiment at ISOLDE (CERN) testing the new concept of post acceleration of radioactive ion beams by using charge breeding of the ions in a high charge state ion source and the efficient acceleration of the highly charged ions in a short LINAC using modern ion accelerator structures. In order to prepare the ions for the experiments s...

Injected beam energy and energy spread are critical parameters affecting the performance of our rapid cycling synchrotron (RCS). A real-time energy monitoring system is being installed to examine the H beam out of the Intense Pulsed Neutron Source (IPNS) 50 MeV linac. The 200 MHz Alvarez linac serves as the injector for the 450 MeV IPNS RCS. The linac provides an 80 μs macropulse of approximate...

The production of d′ dibaryons in heavy ion collisions due to the elementary process NN → d′π is considered. The NN → d′π cross section is estimated using the vacuum d′ width Γd′ ≈ 0.5 MeV extracted from data on the double charge exchange reactions on nuclei. The d′ production rate per single collision of heavy ions is estimated at an incident beam energy of 1 A·GeV within the framework of the ...

The collective transverse flow was analysed within the model of 3-fluid dynamics (3FD) [1]. Model parameters of our previous paper [1] were used, which were fixed to reproduce a great body of experimental data in the incident energy range Elab (1–160)A GeV. These parameters have been varied only in order to study sensitivity to stiffness of the equation of state (EoS). Thus, in addition to the ...

Beam dynamics simulations of the proposed Rare Isotope Accelerator (RIA) [1] driver linac have been done. The RIA driver linac is designed to accelerate stable ion beams from proton to uranium to final energies of 400 MeV/u for the heaviest and about 900 MeV/u for the lightest ions with beam powers of 100 to 400 kW. Two stripping sections are used to increase the charge state of heavy ions and ...

The production of d ′ dibaryons in heavy ion collisions due to the elementary process N N → d ′ π is considered. The N N → d ′ π cross section is estimated using the vacuum d ′ width Γ d ′ ≈ 0.5 MeV extracted from data on the double charge exchange reactions on nuclei. The d ′ production rate per single collision of heavy ions is estimated at an incident beam energy of 1 A·GeV within the framew...

A significant part of the experimental program at FAIR is dedicated to pbar physics requiring a high number of cooled pbars per hour [1]. The primary proton beam has to be provided by a 70 MeV proton linac followed by two synchrotrons. The new FAIR proton linac [2] will deliver a pulsed proton beam of up to 35 mA of 36 μs duration at a repetition rate of 4 Hz. The recent GSI heavy ion linac (UN...
