Design of the ELIMAIA ion collection system

A system of permanent magnet quadrupoles (PMQs) is going to be realized byINFNLNS to be used as a collection system for the injection of laser driven ionbeams up to 60 AMeV in an energy selector based on four resistive dipoles. Thissystem is the first element of the ELIMED (ELI-Beamlines MEDical andMultidisciplinary applications) beam transport, dosimetry and irradiation linethat will be developed by INFN-LNS (It) and installed at the ELI-Beamlinesfacility in Prague (Cz). ELIMED will be the first users open transportbeam-line where a controlled laser-driven ion beam will be used formultidisciplinary researches. The definition of well specified characteristics,both in terms of performances and field quality, of the magnetic lenses iscrucial for the system realization, for the accurate study of the beam dynamicsand for the proper matching with the magnetic selection system which will bedesigned in the next months. Here, we report the design of the collection system and the adopted solutionsin order to realize a robust system form the magnetic point of view. Moreover,the first preliminary transport simulations are also described

Effects of Nutrient and NaCl Salinity on Growth, Yield, Quality and Composition of Pepper Grown in Soilless Closed System

The effects of nutrient or sodium chloride (NaCl) salinity on pepper grown in closed soilless culture systems were studied. A control (2 dS m-1) and two saline nutrient solutions (4 dS m-1) differing in the salt sources (fertilizers or NaCl) were studied. Shoot biomass production as well as total and marketable yield were more affected by NaCl than nutrient salinity. Fruit dry matter and total soluble solids increased in both salinity treatments compared to the control. Total phenol content rose slightly (10%) with NaCl salinity, while the concentration of carotenoids was enhanced by 40% with NaCl compared to the control and nutrient salinity. The results showed that the response of pepper to salinity is both osmotic and ion specific, but a more negative effect was recorded under NaCl stress. Moreover, the highest content of antioxidant compounds in NaCl treated fruits may indicate that NaCl caused more stressful conditions than nutrient salinity
