Towards a Unified Environmental Monitoring, Control and Data Management System for Irradiation Facilities: the CERN IRRAD Use Case

Abstract

The qualification of materials, electronic components and equipment for the CERN High Energy Physics experiments and beyond requires testing against possible radiation effects. These quite complex tests are performed by specialized teams working in irradiation facilities such as IRRAD, the Proton Irradiation Facility at CERN. Building upon the details of the overall irradiation control, monitoring, and logistical systems of IRRAD as a use case, we introduce the motivations for and general architecture of its new data management framework, currently under development at CERN. This infrastructure is intended to allow for the seamless and comprehensive handling of IRRAD irradiation experiments and to help manage all aspects of the facility. Its architecture, currently focused on the specific requirements of the IRRAD facility, is intended to be upgraded to a general framework that could be used in other irradiation facilities within the radiation effects community, as well as for other applications.

Test beam characterization of irradiated 3D pixel sensors

“…The linear front-end is delimited by the large red rectangle. The irradiation took place in the PS-IRRAD Facility [10], with protons of 24 GeV/c momentum. Since the irradiation was not homogeneous, the linear front-end is divided in six regions of different average fluence.…”

Spatial resolution and efficiency of prototype sensors for the LHCb VELO Upgrade

“…A subset of devices were uniformly irradiated with neutrons at JSI [8], up to 8 × 10 15 1 MeV n eq cm −2 , referred to as full fluence. Another group of devices were non-uniformly irradiated at the IRRAD facility at CERN [9], which provides a 24 GeV proton beam that has approximately a two-dimensional Gaussian distribution. This is used to emulate the variation in the fluence anticipated across the inner VELO sensors at the end of their lifetime.…”

“…The IRRAD facility at CERN [9] provides a 24 GeV proton beam that is approximately distributed as a two-dimensional Gaussian, hence yielding a nonuniform fluence profile. After irradiation, the residual activation of the assemblies is obtained by measuring the distribution of hits in the sensor when not exposed to the beam.…”

Radiation hard DMAPS pixel sensors in 150 nm CMOS technology for operation at LHC

“…Proton irradiation was carried out at the Proton Irradiation Facility at CERN [35] with calibrated NIEL and TID damages corresponding to the above specified target values, which are TID of 50 Mrad and fluence of 10 15 n eq /cm 2 . Neutron irradiations were performed at the TRIGA Mark II Research Reactor in the Jožef Stefan Institute [36] to fluences of 10 14 n eq /cm 2 and 10 15 n eq /cm 2 .…”
