Abstract
A second high current accelerator of 400 kV has been installed at the underground laboratory of Gran Sasso, called LUNA II. We describe this new facility as well as measurements of the proton beam characteristics: absolute energy, energy spread, and long-term energy stability. The absolute energy was determined to a precision of 7300 eV at Ep ¼ 130–400 keV using the energy of the capture g-ray transition of 12Cðp; gÞ13N as well as resonance energies at Ep ¼ 309–389 keV of 23Naðp; gÞ24Mg; 26Mgðp; gÞ27Al; and 25Mgðp; gÞ26Al: The resonance studies led to a proton energy spread of better than 100 eV and a long-term energy stability of 5 eV per hourI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
