We shall present the development of a novel extruded plastic bar scintillator (ESB) particle detector with fast timing and three-dimensional track reconstruction capability.

The motivation for this R&D effort is twofold:

1. The MATHUSLA detector - A very large volume of detectors array above the main CERN LHC experiments. With detection surface of order (100 x 100)m2 it will significantly improve the LHC sensitivity for neutral long lived particles (LLP) which escape undetected from the current detectors. Discovery of LLPs would have a major impact on our understanding the complexities and structure of the universe. Conversely, setting limits on LLPs with lifetimes of order 0.1 seconds, may exclude a huge BSM parameter space and set constraints on theories of physics beyond the Standard Model including DM, matter antimatter asymmetry and neutrino masses. A single module of a MATHUSLA prototype with coverage area of 1% of the final size is planned for the next couple of years. It will already provide a similar sensitivity to for very long-lived particles as the reach which can be achieved by the LHC experiments.

2. Search for hidden kings’ tombs -Inspired by the successful muon tomography campaign held a couple of years ago at the large pyramid in Giza, where a hidden chamber was discovered we plan to use a portable tracking device to survey high profile Archaeological sites in Israel. There are strong reasons to believe that there are undiscovered rooms and hidden kings’ tombs on these sites, which we will try to locate using our cosmic ray moun telescopes.

In the talk we shall introduce the basic building blocks of both detectors (MATHUSLA and portable imaging muon telescope), the conceptual design of the full detectors and the related laboratory work.
