| Research Abstract |
When an electron beam is injected into a crystal, a variety of radiation phenomena such as channeling radiation and parametric X-ray radiation (PXR) occur. If the energy of the channeling radiation coincides with the PXR energy, a new radiation process called diffracted channeling radiation (DCR) takes place. The purpose of the present work is to observe DCR and its application to beam energy measurement. We have developed an experimental setup for measuring beam profiles transmitted through a crystal and for detecting X-rays from the crystal. We have succeeded in observing channeling phenomena through measurements of the beam profiles. Also, we have succeeded in observing angular distributions of PXR from channeling electrons. As a next step, the experiment for observing DCR is in progress.
