'Progress-P' laser facility with chirped-pulse amplification in neodymium glass

Abstract

The behaviour of the primary cosmic ray composition near the knee may be considered as being of fundamental importance in studies of the knee nature. In this paper experimental data obtained with the KASCADE array are considered and patterns of the knees in electron and muon size spectra are compared. Such a comparision provides valuable information to check the consistency of the existing experimental data and model predictions. Improvements in the existing simulation methods are essential to ultimately establish the results of the KASCADE mass composition studies. Evidently some revision of hadronic interaction models is needed to eliminate the discrepancy between mass compositions derived with and without KASCADE hadronic calorimeter data.

“…Recently we have developed the 30 TW PROGRESS-P picosecond laser facility based on the similar amplifier chain as PROGRESS facility [5,6]. It is planned to synchronize the both facilities laser pulses for simultaneously interaction them with targets and use of short pulse for backlighting purposes.…”

“…The experiments were carried out with the use of the PROGRESS-P laser, 9 operating at a wavelength of 1.054 µm with a pulse duration of 1.0-1.6 ps and an energy of 6-8 J. A schematic of the experiment is presented in Fig.…”
