Irradiation facility ( Proton/Neutron)

The characteristics of the proton irradiation facility (IRRAD1) are:

o shuttle + x/y stage

o primary proton PS beam: PS-T7 beam line

o proton energy: 24 GeV

o proton flux: 2 to 4 10^9 p cm-2 s-1 (10h for 10^14 p cm-2)

The characteristics of the neutron irradiation facility (IRRAD2) are:

o shuttle

o in DIRAC beam dump: PS-T8 beam line

o neutron energy: 50 keV - 1 MeV

o proton/pion energy: 0.3 - 4 GeV

o neutron flux: 2 to 7 10^9 n cm-2 s-1 (10h for 10^14 n cm-2)

o proton/pion flux: ~10% that of neutrons

The areas provide a number of advantages:

o only possibility for neutron irradiation at CERN,

o high particle flux in reasonable time,

o fast turnaround, short irradiation ,

o possibility to move samples into beam without entrance into irradiation area,

o use of well-developed PS East Hall infrastructure.
