Cheng is now a Ph.D. candidate in physics at Karlsruhe Institute of Technology (KIT), Germany. He attained a Bachelor of Science in physics and a Master of Engineering in nuclear technology and applications, both from the Physics Department of Peking University in China.
During his Master’s degree in the field of accelerator physics Cheng gained experience in designing a Compton Back Scattering (CBS) X-ray source. In this way X-rays are generated by laser light scattered off the relativistic electron beam. The laser pulses are amplified in a storage cavity and electron beam provided by an energy recovery linac. Cheng has also had a broad experience related to superconducting accelerator physics and engineering issues such as Cs2Te photocathode fabrication, superconducting cavity tuning and Radio Frequency (RF) studies.
