Abstract
Liquid scintillator, based on 1-methylnaphthalene and a new solvent IPN, which emitting in the green spectral range, were studied. The scintillation efficiency in vacuum was 22-32% higher compared to the level in air, and the intrinsic light yield of the scintillators reached 41-50% of the yield from anthracene. The increased level of the scintillation efficiency was virtually retained in the atmosphere of inert gases (Ne, Ar, and CO2). The light yield of liquid scintillators based on 1-methylnaphthalene (in air) and IPN (in vacuum) were virtually independent of the temperature in the interval from -5 to +20 degrees C. Liquid scintillator on the basis of 1-methylnaphthalene and a scintillation additive R6 (concentration 3 g/l) also exhibited a highly stable light yield (+0.024%/K) in the temperature interval from +20 to +60 degrees C.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
