Conceptual Design of Rapid Cycling Booster for Accelerator Facility for Cancer Therapy

The rapid cycling booster synchrotron is used as pre-accelerator for carbon ion facility for cancer therapy. Booster provides about 1010 carbon ions per second at extraction energy 30 MeV/unit, at a repetition rate of 10 Hz. At the same time the booster can be used for acceleration of protons and delivers about 1012 protons per minute at a maximum extrac- tion energy of 250 MeV in separate irradiation port.

RADIATION MODIFICATION OF POLYETHYLENE: INDUSTRIAL TECHNOLOGIES BASED ON EB ACCELERATORS

Radiation-chemical modification of polyethylene with accelerated electrons makes a basis of high-profitable industrial technologies, including: - manufacture of radiation- crosslinked polyethylene material and products, - manufacture of heat-shrinkable pipeline insulation material, - manufacture of heat-shrinkable polyethylene pipes for electrical en- gineering, - manufacture of heat-shrinkable polyethylene film. The paper gives a descrip- tion of the commercial technologies and used equipment

METHOD FOR CALCULATION OF THE MAIN PARAMETERS OF ELECTRON BEAM ACCELERATORS USED IN INDUSTRIAL TECHNOLOGIES

A universal method was developed to calculate distribution of absorbed doze of the accel- erated electrons in the energy range from 0.2 to 10 MeV. The method is used to make a final choice of the main parameters and electron beam configuration for industrial tech- nologies.
