Abstract
We present a scintillator-based detector able to measure the proton energy and the spatial distribution with a relatively simple design. It has been designed and built at the Spanish Center for Pulsed Lasers (CLPU) in Salamanca and tested in the proton accelerator at the Centro de Micro-Análisis de Materiales (CMAM) in Madrid. The detector is capable of being set in the high repetition rate (HRR) mode and reproduces the performance of the radiochromic film detector. It represents a new class of online detectors for laser–plasma physics experiments in the newly emerging high power laser laboratories working at HRR.
Highlights
The advent of high power lasers (HPL) working at high repetition rate (HRR) is nowadays a reality and HRR proton sources are routinely produced with energies ranging from a few to tens of MeV

Summary
The advent of high power lasers (HPL) working at high repetition rate (HRR) is nowadays a reality and HRR proton sources are routinely produced with energies ranging from a few to tens of MeV. The group from Dresden[10] proposed a stack of scintillators placed one after the other, as in the RCF stack, with a readout system looking at the transversal scintillation emission. Such devices have been tested in a proton beam accelerator and are currently used in the Dresden laboratory. Both detectors can partially reproduce the working mode of the RCF stacks even though they increase the complexity of the viewing system and the data interpretation
