Based on the improvements of beam line, LLRF system and 2K cryogenic system, stable operation of the DC-SRF injector has been carried out recently. Electron beams with 3.4 MeV energy and the currents of ~1mA in a macro-pulse mode was obtained. As the first application of this DC-SRF injector, THz radiation produced with a 10 period undulator was detected. As another application, ultra fast electron diffraction (UED) was successfully carried out with DC-SRF injector. </span><br><br><br><span style="color: rgb(0, 0, 0);" data-mce-style="color: #000000;">Wednesday, May 13, 2015 </span><br><span style="color: rgb(0, 0, 0);" data-mce-style="color: #000000;">11 a.m. </span><br><span style="color: rgb(0, 0, 0);" data-mce-style="color: #000000;">CEBAF Center, Room F224-225 </span><br><br><br><span style="color: rgb(0, 0, 0);" data-mce-style="color: #000000;">Seminar archives are found here:</span> <a href="https://www.jlab.org/accel/seminars.html" target="_blank" data-mce-href="https://www.jlab.org/accel/seminars.html">https://www.jlab.org/accel/seminars.html</a><br><br></div><div>-- <br></div></div></div></div><br></div></div><br>_______________________________________________<br>Accelerator_staff mailing list<br>Accelerator_staff@jlab.org<br>https://mailman.jlab.org/mailman/listinfo/accelerator_staff<br></div></div><br>_______________________________________________<br>Accelerator_staff mailing list<br>Accelerator_staff@jlab.org<br>https://mailman.jlab.org/mailman/listinfo/accelerator_staff<br></div></div></body></html>
