“…Irradiation tests were carried out in 2012 using the IRRAD3 beam line of the Proton Synchrotron (PS) Irradiation Facility [9] at CERN. The IRRAD3 provides a beam of 24 GeV protons, and the structure of the beam is defined by the operation cycle of the PS accelerator.…”

“…In order to control the position, shape and alignment of the irradiation beam, the IRRAD facility uses a specific type of detector called Beam Profile Monitor (BPM) [13]. These detectors are composed of arrays of 4×4 mm 2 Cu pads that generate an electron charge via Secondary Electron Emission when the proton beam impinges on them [14].…”

“…They are used to align the samples that are placed on the IRRAD tables in the beam. Even though these detectors have different forms and purposes, they use the same data acquisition and processing system architecture [13].…”

“…In contrast with the beam profile display mentioned earlier and used in operation, which takes into account only the intensities on the two axes, the 3D reconstruction process uses all the acquired BPM intensities, via a SciPy function [15] for the least square minimization. The implemented method has been validated over hundreds of spills against other fitting methods [13] ( Fig. 9).…”

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.

“…During operation, the part to the sensing pads is placed directly in the beam and, via Secondary Electron Emission (SEE) [3], a charge proportional to the beam intensity, is generated on each pad. Via the multi-pin connector, the BPM is connected to dedicated readout electronics [4], which measures the amount of charge generated on each pad for each spill, thus resulting in a single beam profile per spill.…”

In High Energy Physics (HEP) experiments built at the European Organization for Nuclear Research (CERN) it is a common practice to expose electronic components and systems to particle beams, in order to assess their level of radiation tolerance and reliability when operating in a radiation environment. One of the facilities used for such tests is the CERN Proton Irradiation Facility (IRRAD), where several hundreds of samples are irradiated yearly with a 24 GeV/c proton beam extracted from the CERN Proton Synchrotron (PS) accelerator. In order to properly control the irradiation beam and guarantee reliable results during the tests, Beam Profile Monitor (BPM) devices are used. The current BPMs are fabricated as standard flexible PCBs featuring a matrix of metallic sensing pads. When exposed to the particle beam, secondary electrons are emitted from each pad, thus generating a charge proportional to the particle flux crossing the pads. The charge is measured individually for each pad using a dedicated readout system, and so the shape, the position and the intensity of the beam-spot are obtained. Beam profile determination of high intensity beams implies the usage of non-invasive and radiation tolerant (~10 18 p/cm 2 /year) devices. This study proposes a new fabrication method using standard microfabrication techniques in order to improve the radiation tolerance of the BPMs while greatly reducing the device thickness, thus making them also appropriate to be used for the monitoring of lower energy particle beams.
