Portable Glass-RPC Telescope for Muography and Future Applications at Laser Wake Field Accelerators

Abstract

We report a 2025 beam test at ELBA, the multi-GeV laser wakefield accelerator at ELI Beamlines, using a Resistive Plate Chamber (RPC) telescope with an active area of 16 * 16 cm2. The portable design sup- ports autonomous operation in challenging environments. Previous cosmic-ray measurements established its tracking capability for muography. During the campaign at ELBA, 30 f s long, 0.5 PW laser pulses in- teracted with a plasma target at a 0.2 Hz repetition rate, where a tungsten converter upstream of the beam dump enhanced muon production. This was the first deployment of an RPC telescope in a high-power laser environment. The detector remained operational in the presence of radiation and electromagnetic interference. Although parasitic running and limited statistics prevented definitive identification of beam- induced muons, the measurements offered insight into background activity and showed evidence of re- constructed tracks. They establish the feasibility of a dedicated campaign with controlled beam conditions and improved muon sensitivity. This contribution forms part of the International Muography Workshop 2026 proceedings.
