Research Abstract

A miniature X-ray source using electron emission from a pyroelectric crystal excited by a laser light was developed without an external high voltage power supply. Electron emission from the crystal and X-ray generation from the counter electrode were observed with a continuous wave (CW) infra-red (IR) laser light. The peak and average X-ray yields using a 0.89 W CW Neodymium-doped yttrium lithium fluorides (Nd:YLF) laser light were 234 and 78 MBq, respectively, while those using a 5 W CW fiber laser light were 9.8 and 3.2 times higher than those using a CW Nd:YLF laser light. The miniature X-ray source capsule was designed for mounting on an endoscope.
