Our research group has achieved results such as the discovery of an unknown giant cavity inside the Pyramids of King Khufu in Egypt through cosmic ray imaging using nuclear dry plates. Currently, we are developing a new technology to explore underground structures by expanding the technology that has been used for aboveground structures. In this presentation, we will report on the development status of a nuclear dry plate detector that can be inserted into a Φ75 mm PVC pipe, as well as simulations and preparations for its demonstration test.
