18. Radiological assessment for the renovation of the CERN East Area primary area and secondary beam lines

Mr Arnaud DEVIENNE (CERN)

22/09/2022, 10:20

2. Shielding and dosimetry

Oral

The East Area renovation project aimed at completing by the end of Long Shutdown-2 the consolidation and renovation of the CERN East Area, served by the Proton Synchrotron accelerator since more than 55 years. In particular, the Primary Area and the secondary beam lines of the East Area have been completely redesigned, highlighting some singular safety challenges.

The East Area receives a...

22. Radiation protection assessment of the AMBER Drell-Yan program

Claudia Ahdida (CERN)

22/09/2022, 10:40

2. Shielding and dosimetry

Oral

In the context of the Physics Beyond Colliders Project, a QCD facility named AMBER/NA66 was developed as a successor of the COMPASS experiment. AMBER is located in the surface hall EHN2 in the CERN SPS North Area. The approved physics program of AMBER includes, amongst others, measurements of the pion-induced Drell-Yan process. This process shall be studied with a high-intensity 190 GeV/c pion...

46. Fundamental investigation on concrete composite for radiation shielding in facilities

Dr Ken-ichi Kimura (Fujita Co.)

22/09/2022, 11:00

2. Shielding and dosimetry

Oral

For the buildings where radiation exists, such as nuclear power plants or accelerator facilities, concrete is not only used as structural materials but also widely used as shielding materials. On the other hands, only few discussions had conducted for the constant of shielding calculation. In addition, very old and/or foreign data have been used for the calculation, such as ANL-5800 and...

43. Sensitivity study of water and iron contents for neutron deep penetration in concrete

Dr Hiroshi Iwase (KEK)

22/09/2022, 11:20

2. Shielding and dosimetry

Oral

The sensitivity of water and iron contents to the attenuation length of neutron deep penetration in concrete is discussed. According to previous researches, the contents of water in radiation shielding concretes varies from about 2 to 20%, and the iron 1 to several %. It is noted that the iron in this study means the frame itself embedded inside concrete against the tensile strain. Since the...

38. ARI-SXN beamlines radiation shielding analysis

Dr Ricardo dos Santos Augusto (Brookhaven National Laboratory)

22/09/2022, 11:40

2. Shielding and dosimetry

Oral

ARI (NanoARPES and NanoRIXS) and SXN (Soft X-ray Nanoprobe) are a pair of soft x-ray beamlines under development at NSLS-II, in the framework of the NEXT-II project, which is funded by the United States Department of Energy Basic Energy Sciences (DOE-BES).

Each beamline will have two branches that will be provided with soft x-rays from two elliptically polarizing undulators, with periods of...

33. The skyshine problem at the STAR facility due to the beam dumps and the dark current leakage

Federico Chiarelli (National Institute of Nuclear Physics (INFN))

22/09/2022, 12:00

2. Shielding and dosimetry

Oral

STAR (Southern Europe Thomson Back-Scattering Source for Applied Research) is an “inverse-Thompson scattering” facility based in the Calabria’s University campus in Rende, Italy. It will be a facility for advanced scientific investigation on fundamental and applied materials research, with monochromatic X-rays production.
The facility upgrade consists in two electron beam lines: the first...
