Experimental data from RIBF experiment nr. NP1512-RIBF104R1

Introduction The dataset contains experimental data collected at Radioactive Isotope Beam Factory (RIBF) of the RIKEN Nishina Center (Japan) in course of experiment nr. NP1512-RIBF104R1 entitled"Two-proton correlations in the decay of 54Zn". The goal of the experiment was to study decays of the most neutron-deficient isotope of zinc, 54Zn, and nuclides in its vicinity with help of the Warsaw Optical Time Projection Chamber (OTPC).The results include information on decays with emission of protons from 56Zn, 55Cu, 55Zn, and 54Zn.The dataset contains raw data for all events which were analysed, and described in a preprinthttps://arxiv.org/abs/2509.25061v1. This paper will be submitted for publication in Phys. Rev. C. Description The record contains 5 files. Four of them, named by the isotope symbol followed by "Raw", contain decay events recordedby the OTPC, corresponding to this isotope. Each event is uniqely identified by the first 10 characters of the filename, and there are a few such files for each event. Files with the extension "png" representthe images taken by CCD cameras. All others contain waveforms recorded by oscilloscopes. The fifth file "otps-scopes-readers-master.zip" contains software routines to read the oscilloscopefiles. The subdirecory "[example]" has two examples of using these routines and a real event toread by these examples. The file README.md provides instructions how to install the examples.
