13 May 2020 | | Abstract: | In the framework of the ATTRACT-uRANIA project, funded by the European
Community, we are developing an innovative neutron imaging detector based on
micro-Resistive WELL ($mu$ -RWELL) technology. The $mu$ -RWELL, based on the
resistive detector concept, ensuring an efficient spark quenching mechanism, is
a highly reliable device. It is composed by two main elements: a readout-PCB
and a cathode. The amplification stage for this device is embedded in the
readout board through a resistive layer realized by means of an industrial
process with DLC (Diamond-Like Carbon). A thin layer of $^{10}$B on the copper
surface of the cathode allows the thermal-neutron detection through the release
of $^7$Li and $alpha$ particles in the active volume. The $^{10}$B technology
has been developed to be an efficient and convenient alternative to the $^3$He
shortage. The goal of the project is to prove the feasibility of such a novel
neutron detector by developing and testing small planar prototypes with readout
boards suitably segmented with strip or pad readout, equipped with existing
electronics or readout in current mode. Preliminary results from the test with
different prototypes, showing a good agreement with the simulation, will be
presented together with construction details of the prototypes and the future
steps of the project. | | Source: | arXiv, 2005.6260 | | Services: | Forum | Review | PDF | Favorites | |
