We offer to your attention a preprint “Recovery of the software and hardware complex for film information processing (FIP) for bubble chambers” P10-2023-18 issued by the JINR Publishing Department. The authors are Anton Baldin, Alexander Belyaev, Alexey Beloborodov, Victor Rikhvitsky, Alexander Troyan.

The complex for film information processing (FIP) obtained on bubble chambers has been restored. A procedure for the geometric reconstruction of spatial coordinates obtained from measurements on photographs of bubble chambers is presented. This procedure is a significant modification of the previous one. The work of the FIP is demonstrated in the photographs of the 1-meter hydrogen and 2-meter propane chambers, which were obtained during the measurement sessions of 1960 – 2000 at JINR. The reconstructed FIP complex adequately corresponds to, and in some ways even surpasses, the previously existing complex in the main parameters: spatial resolution and processing speed.

The study has been carried out at the Veksler and Baldin Laboratory of High Energy Physics JINR.
