// Detector development for particle and nuclear physics

Desenvolvimento de Detectores para Física de Partículas e Nuclear

Neutrons as a non-ionizing radiation cannot be detected directly, but only through the reaction products in converter materials. Only a few isotopes can be used for this purpose, with 3He being the most common. However, the 3He shortage results in a change of paradigm, and there is today a widespread need for 3He-free Position Sensitive Neutron Detectors (PSNDs) with enhanced performance for applications ranging from neutron scattering science to homeland security. The European Spallation Source (ESS), currently under construction, is a prime example and a driver of such need for high performance PSNDs to fully explore its potential.

10B is one of the most promising alternatives to 3He. However the maximum detection efficiency achieved with a single layer of a solid neutron converter such as 10B4C is only about 5%. As a solution, the LIP team proposed a new detector concept based on 10B4C coated RPCs, which takes advantage of the naturally layered configuration of RPCs. The feasibility of the concept was successfully demonstrated, and the work developed at LIP is now integrated into the Horizon-2020 EU research project Science & Innovation with Neutrons in Europe in 2020 (SINE2020).

Our studies demonstrate that 10B-RPCs can offer a unique combination of characteristics: very high spatial (FWHM50%), strong design modularity, good scalability, robustness and low price per unit area. To make these detectors s a competitive technology for future applications, the near-future objectives are to enhance the already demonstrated counting rate (~103 Hz/cm2) by two orders of magnitude and to achieve a neutron/gamma rejection factor better than 105.
