A ceramic-insulated ball-anode (CiB) element that consists of a ceramic insulator, cathode lines, ball-shaped anodes, and anode lines was developed, and an irradiation experiment was performed using a Cf-252 neutron source. An electric field simulation of CiB element was conducted and strong electric fields of more than 10 V/m was obtained by the calculation using the finite element method. The neutron-induced signals of all pixels were observed using 8 8 pixel small-sized test element under Cf-252 neutron irradiation.
