Research Abstract

A large size X-ray detector was attached t an electron microscope, JEM-120CX construct a coincidence electron microscope. For this, objective lens system was modified to enable the X-ray detector to be mounted. The results obtained so far are as follows:
(1) A specific large size X-ray detector with a scintillatior of linch in diameter was manufactured at Horiba Ltd.
(2) This X-ray detector was attached to JEM-120CX to detect characteristic X-rays from a sample by pulse height analysis and for this the pulse height analyzer system was constructed.
(3) Position sensitive detector (PSD) was bought for a high speed two dimensional detector and attached to a photomultiplier to realize a position sensitive photomultiplier (PSPM).
(4) The high speed signal processing electronic system was made to connect with the PSPM to confirm that this system has excellent performance; rising time 5.5ns, delay time 17ns, and broadening of the response timing 1.0ns.
(5) Preliminary investigation of coincidence electron microscope was performed and we have successful confirmed that distinct peak of coincidence was observed at delay time 26ns.
In conclusion, the imaging system with PSPM has been successfully developed assuring the sufficient spatial resolution and high sensitivity for the coincidence TEM under construction. The present results are encourageous enough to realize a coincidence TEM. The next step is to develop a fast-response X-ray detection system with high detection efficiency and to attach a coincidence gate on the electronic system.
