Filed: 1985-02-15
Abstract: PURPOSE:To improve the reliability by forming the neutron-sensitive substance through drive process employing a spattering device thereby strengthening the adhering force with anode or cathode thus facilitating handling under manufacturing. CONSTITUTION:Following method is employed for forming neutron-sensitive substance 8-1, 8-2 onto the surfaces of anode 1 and cathode 2. A ceramic BN target having high composition ratio of isotope 10B is fixed to the cathode of spattering device S while the anode 1 of neutron detector 10 is fixed to said anode. Upon evacuation of the device S, Ar gas is led in then while evacuating, high frequency voltage is applied between the anode and cathode of the device S to produce glow discharge thus to impinge Ar<+> ions with high speed against BN target. Consequently, BN particles arepopped out from the surface of BN target to impinge with high energy against the surface of anode 1 thus to form a rigidly adhered groove film. When forming the substance 8-2 onto the inner face of cathode 2 of detector 10, the cathode of the device S is inserted into the cathode 2 to perform similar spattering with that for the anode 1.
