deuteron ions inside the neutron generator. e pictures of assembled ange and
of the assembled ange with alpha detector are shown in Figures 3.20 and 3.21,
respectively. e ange thus assembled has been sent to ermo Electron Inc. for
nal mounting on the neutron generator API-120 by laser welding.
e scintillator has been mounted on a standard stainless steel CF63 ange
equipped with a sapphire window (3mm thick, 48mm diameter) without any
optical grease, as required in the sealed neutron generator manufacturing pro-
cedure. e surface of the YAP:Ce crystal has be
