Opis:: The purpose of this paper is to present the Monte-Carlo calculations performed to design a special element called gamma blocker (GB), necessary to stop the gamma radiation in the Accelerator-to-Target (A2T) section of European Spallation Source (ESS) linac. Very high levels of gamma radiation emitted backward from the activated target through the beam pipe could effectively block any human intervention close to the beam transport system. The residual dose rate in the linac tunnel was calculated without and with different GBs as a function of time. The fi nal GB material and dimensions are proposed.

Opis:: The European Spallation Source (ESS) is a collaboration of 13 European countries to build the world’s most powerful neutron source for research. The project, situated in the south of Sweden, is approaching the end of the construction phase, and the fi rst scientifi c results are planned for 2023. This paper gives an overview of mechanical design of the gamma blockers (GBs) in the accelerator to target (A2T) and dump line (DmpL) sections. The presence of GBs in the beam line should limit the gamma radiation emitted from the activated tungsten target and beam dump to allow the safe access of the staff to the machine. The presented design allows for effi cient operation and the same shutting time independently of the vacuum status.

Opis:: For the development of an effective cargo-scanning system, an intrapulse energy switching has been tested at the National Centre for Nuclear Research (NCBJ) with the possibility to change the beam energy within a 4 μs pulse of the linear electron accelerator (linac). Modifi cation of the electron energy is achieved through the beam-loading effect in a standing-wave accelerating structure equipped with a triode gun. Construction of the machine and the achieved results are presented in this article.
