Radiation monitors

Tender description

ISIS is a world-leading centre for research in the physical and life sciences in the UK Research and Innovation - STFC based at Rutherford Appleton Laboratory (RAL, the ‘Agency’) near Oxford. ISIS is an intense pulsed neutron source providing beams of neutrons and muons to enable scientists to study the structure and properties of matter for the benefit of science and engineering in the UK and abroad. Our suite of neutron and muon instruments gives unique insights into the properties of materials on the atomic scale. The contracting authority is looking for bidders capable of offering the required on-line radiation monitor system.

ISIS is an intense pulsed neutron source providing beams of neutrons and muons to enable scientists to study the structure and properties of matter for the benefit of science and engineering in the UK and abroad. Our suite of neutron and muon instruments gives unique insights into the properties of materials on the atomic scale. STFC support a national and international community of more than 3 000 scientists for research into subjects ranging from clean energy and the environment, pharmaceuticals and health care, through to nanotechnology and materials engineering, catalysis and polymers, and on to fundamental studies of materials. ISIS facility is formed by a linac and a proton synchrotron accelerator that delivers an 800 MeV proton beam to 2 different tungsten based targets where the 2 intense pulsed neutron sources are created (see Annex I for the proton beam characteristics). Next to each target there are about 20 beamlines where the scientists perform their experiments. In order to monitor the radiation generated in the different areas of ISIS, the ISIS Health Physics (HP) staff (based at RAL) is looking for an on-line ionising radiation monitor system – RMS for X-ray, gammas and neutrons. This system will allow them to get the radiation dose rate and accumulated dose values in a gamma ray and neutron mixed radiation field at any ISIS location in an on-line basis and populating a time related database. Also a connection to accelerator or beamline systems will be possible via a dual relay output with set points configurable to the dose rate or dose accumulated values (either for gammas, neutrons or total values). The Contracting Authority is looking for bidders capable of offering the required on-line radiation monitor system used by HP.
