On June 20, scientists from the Institute of High Energy Physics (IHEP) announced that China’s first C-band (5712MHz) energy doubler was

The C-band (5712MHz) energy doubler

The announcement was made after Roberto Boni and David Alesini, the linear accelerator microwave experts from the Istituto Nazionale di Fisica Nucleare (INFN), witnessed an acceptance test of the C-band energy doubler from June 17 to 20 at IHEP.

This energy doubler is one of the key devices of the Sorgente Pulsata Auto-amplificata di Radiazione Coerente (SPARC) Project at INFN. IHEP is responsible for the design and the fabrication of the energy doubler. The cold test showed that all the technical requirements have been reached or exceeded. Peak power gain of 6.2 has been obtained with an input pulse width of 2.5μs. Italian experts were satisfied with the test results and expressed the wish to have broader cooperation in the future.

The successful development of the C-band energy doubler indicates that IHEP’s microwave technology of linear accelerator has made a big step further. IHEP scientists could develop international-recognized S-band, C-band and even X-band products by adopting the current microwave technology.
