What is it about?

The article describes a scintillator stack detector designed to measure proton beams in real time during experiments on laser-plasma interaction. It also describes the signal reconstruction method based on Monte Carlo simulations and compares the results with those measured by a common Radiochromic films (RCF) stack detector.

Why is it important?

With the latest progress in laser technology, high repetition rate experiments on proton acceleration using high-power lasers have become a reality. Common detectors like RCF can no longer be used in such experiments because they require long post-processing procedures. Therefore, there is a need for an "online" detector that could replace the common passive diagnostics. Scintillator-based devices are great candidates for shot-to-shot measurements since their response time is short and the signal can be measured remotely using, for example, CMOS cameras.
