Improvements and Status of the Proton Electrostatic Accelerator, V2

  •  Institute of High Energy Physics, The Chinese Academy of Sciences, Beijing 100080

  • The proton electrostatic accelerator, V2 completed in 1958 has been operated for 40 years. At present, the highest energy is 2.4 MeV. The intensity of the proton beam is 0.6-2.5μA. The stability of the power suPPly for the magnetic analyzer is ±0.01%. The energy resolution of the proton beam is ±0.1%. The arrangement of the equipotential rod along the charging belt was changed from the original design, the dismantiling and installing of the belt takes much less bine and labor. A three. forked vacuum pipe was installed, which can be used to extract external proton beams. ms accelerator is mainly used for nuclear analysis since the seventies. Recently the ionoluminescence (IL) method was used to study the chemical states of iron in a plagioclase sample with the external proton beam, both ferrous and ferric iron peaks (Fe2+, Fe3+) from the plagioclase sample were detected in the IL emission spectrum.

Abstract: The proton electrostatic accelerator, V2 completed in 1958 has been operated for 40 years. At present, the highest energy is 2.4 MeV. The intensity of the proton beam is 0.6-2.5μA. The stability of the power suPPly for the magnetic analyzer is ±0.01%. The energy resolution of the proton beam is ±0.1%. The arrangement of the equipotential rod along the charging belt was changed from the original design, the dismantiling and installing of the belt takes much less bine and labor. A three. forked vacuum pipe was installed, which can be used to extract external proton beams. ms accelerator is mainly used for nuclear analysis since the seventies. Recently the ionoluminescence (IL) method was used to study the chemical states of iron in a plagioclase sample with the external proton beam, both ferrous and ferric iron peaks (Fe2+, Fe3+) from the plagioclase sample were detected in the IL emission spectrum.
