在伽马10中，高功率插头和中央ECRH的升级计划已经开始，用于研究等离子体电势的物理学和证明串联镜优势的高等离子体性能的演示。为此目的，从2003年起与日本原子能机构合作开发了一种新的高功率（升级）回旋管，现在在伽马10上安装了三个升级回旋管。2004年的第一个回旋管在回旋管窗口处输出约500 kW的功率，对应于400 kW的等离子体注入功率。2005年，从第二个窗口获得了570 kW的功率，主要在模式转换器中进行了改进。在470 kW注入条件下，获得了离子约束电位Φc = 3 kV的新记录，比2003年以前的实验值提高了4倍。对于中央ECRH系统，使用JFT-2 M ECH系统的直流电源进行了直流电源升级，系统在MOU时输出400 kW，升级回旋管。利用新型高效天线、传输线和升级回旋管进行了中心ECRH实验，初步实验结果表明Te ≥ 500 eV。
In GAMMA 10, the upgrade program of high power plug and central ECRH have started for the study of the physics of plasma potential and the demonstration of high plasma performance proving the tandem mirror advantage. A new high power (upgrade) gyrotron has been developed in collaboration with JAEA from 2003 for this purpose and now three upgrade gyrotrons were installed in GAMMA10. The first gyrotorn in 2004 outputted about 500 kW power at the gyrotron window, corresponding to 400kW injection power to plasma. In 2005, the power of 570 kW at the window was obtained from the second one, which was improved mainly in mode converter. These gyrotron were applied to plug cells and a new record value of ion confining potential Φc = 3kV was obtained at 470 kW injection, which is four times higher than the previous value before 2003. For the central ECRH system, the upgrade of DC power supply was conducted using the DC power supply from JFT-2M ECH system and the system outputted 400kW at MOU out with the upgrade gyrotron. The central ECRH has been conducted with the combination of the new efficient antenna, transmission line and the upgrade gyrotron, and the initial experiment resulted Te ≥ 500eV.
