This facility is based on the Lower Hybrid Heating and Current Drive System for the old Frascati Tokamak (FT).
It is currently used to test at full power level the microwave components of the terminal transmission line of the Lower Hybrid Heating and Current Drive System for FTU
The main characteristics of the facility are resumed in the following table.
| Nominal frequency | 8 GHz |
| RF Source | Klystron |
| Specific RF Power | 125 kW |
| Number of Sources | 4 |
| Total RF Power (nominal) | 500 kW |
| Maximum Pulse Length | 1 s |
| Minimum Duty Cycle | 1/600 |
The output power is delivered through 4 independent standard WR 137 rectangular waveguides, one for each klystron.
The facility is based on a long pulse klystron amplifier whose main characteristics are in the following table.
| Type | VKX 7879A |
| Manufacturer | Varian Ass.es |
| Output Power | 130 kW |
| Output Frequency | 8 GHz |
| Beam Voltage | 38 kV |
| Beam Current | 7 A |
The facility is conceived so that it is possible to operate one or more klystrons according to the characteristics and the requirements of the device under test.
