An Implementation of new electronic tube power source for the CSNS 3MeV RFQ | |
|

| Electronic tube is a great invention since the beginning of last century, which strongly promoted the development of the electronics industry. After more than forty years of research, the technology of electronic tube is fully matured, which is usually used at 300MHz or less. The Power source of CSNS 3 MeV RFQ works on 324MHz and 700kW. On account of the low cost,small volume and large load capacity, refusing the usual tool -Klystron,we first applied the 4616 tetrode to design RFQ power source for CSNS. We tried a variety of methods to find the best working condition in the process of commissioning. For example, we properly increased the inductors and capacitors of PSM power supply output high voltage line to suppress over shoot and improve the stability of positive pressure. We also add nitrogen to the output cavity to increase the pressure resistance of anode current. Finally, for the first time, Each of tetrode power source could keep running stably at 324MHz and 350kW for more than 48h. This also provides a new idea for the selection of accelerator power source. | ||
