This paper describes a 1300 MHz klystron and modulator system recently constructed for the Advanced Free Electron Laser (AFEL) project at Los Alamos National Laboratory. The AFEL is a very compact high power FEL. The new RF system was developed to supply up to 30 megawatts peak power, 30 microsecond pulse width and up to 100 hertz repetition rate. The average RF output power goal is 50 kilowatts. The fifty kilowatts will allow the FEL to produce at least 1 kilowatt of infrared light output. The key feature of an FEL RF system is phase and amplitude stability. The modulator is a thyratron-switched line-type design. The major goals of the modulator are reasonably compact size and automated operation. One notable feature is the use of five large switching power supplies in parallel to charge the pulse forming network. These supplies are a major contributor to the compact size of the modulator. The design of the modulator will be discussed along with the techniques employed to achieve stability, compact size, and automated operation. Modulator and RF performance wiil be described.

Four identical line modulators have been designed and built as part of the 550 MeV positron-electron linear accelerator for Frascati Laboratory. This linac has been designed and is provided by Titan Beta. These modulators are capable of delivering a 100 MW peak power video pulse with a 4.5 psec flat top at 50 pps. Each modulator is resonantly charged with a requirement of +0.1% pulse to pulse amplitude stability. The four modulators are built and are under test at the factory. This paper describes the design and provides the factory test results.

There is considerable interest at present in extending the high repetition rate capabilities of high voltage spark gaps whilst maintaining fast switching times. Devices with these capabilities would be suitable for applications such as the pulse sharpening of very high voltage microsecond risetime pulses. The results of tests on a number of two electrode compact sealed spark gaps are described. These devices are stand-alone components of envelope size, 60 mm diamter and 45 mm length. The devices were tested using half sine pulses of 500 ns risetime at repetition rates of up to 1 kHz. Successful operation at 120 kV, 1 kHz was achieved whilst maintaining a measured collapse time of 2 ns. is believed that this time was limited by the inductance of the test housing, since previous tests on lower voltage devices of similar gap spacing showed the collapse time to be less than 500 ps. Measurements of breakdown voltage and jitter at increasing repetition rates showed that a two stage recovery of voltage hold off capability occurred in agreement with other reported results. It

The pulse shape is rectangular, has a duration of 4 ns and a risetime of 120 ps. The system can be operated at pulse repetition rates up to 1500 Hz and electric field levels up to 125 kV/m. Both voltage and pulse rate are continuously adjustable over these ranges may be operated in any combination.

A trigatron spark gap, T-150, rated at 300 kA for a single shot, has been evaluated for repetition rate applications towards 100 Hz at reduced currents. Switching voltage range was varied from 10 to 40 kV via gap-pressure and gas flow settings. Its trigger generator, producing 8-20 kV pulses, is solid-state based and fiber optically linked for electrical isolation. Trigger energy has been minimized to prolong the overall switch life, drawing input power of <75 W at up to 100 Hz. Demonstrated repetition rate, lifetime, and prefire performance indicated the use of the switch as an alternative to ignitrons or thyratrons in medium power modulators. Introduction Physics International (PI) has fielded a number of single-pulse closing switches172 for high energy capacitor banks to drive electric launchers.3-5 To reduce size and weight of the switch, add a repetitive firing capability, and minimize trigger power, a trigatron gas switch, T-150, has been developed along with the TG-10 trigger generator.6 In this paper, we report on initial results in repetitive firing of the switch at reduced currents. Figure 1 shows a photograph of the switch-trigger package. The highly compact TG1 OB trigger generator is solid-state based and battery powered, producing 20 kV open circuit output voltage. The generator employs fiber-optic isolation to ensure safe, reliable operation in a noisy environment. An ac-powered version (TG-1292R in Figure 1) is customized for increased power, higher repetition rate applications. Trigger energy is minimized to limit the trigger power. The generator draws <75 W at up to 100 Hz. The switch-trigger package can be controlled via fiber optic links, allowing their use in a "floating" configuration in modulator or capacitor bank circuits. T-I50 TG-100 TG-1292R Figure 1.

Single pulse performance of the T-150 lies between those for the high charge transfer spark gaps (namely, PI's two-electrode, seriesinjected trigger switches Table 1-A) and high voltage mid-plane trigger switches (see PI T-508 Table 1-C).

Two computer control systems are described for providing remote monitor and control of high power klystron modulators. The first system utilizes a Macintosh I1 FX control computer with National Instruments LabView software to control a number of devices. These include a GPIB CAMAC crate controller, CAMAC analog and digital I/O modules, a digital delay generator, and an oscilloscope. A top level software screen allows the operator to view the overall status of the modulator and control high level operator functions. Status indicators inform the operator of general modulator conditions (whether interlock chains are satisfied, etc.). Lower level screens can then be brought up which show individual interlock status, allow control of the digital delay generator, and allow setup and acquisition of waveforms from the digital oscilloscope. The second computer control system represents a more complex system in which more functions are monitored and controlled by the computer. Up to 150 signals are controlled with this system, which is based upon the use of a 486 type computer with National Instruments LabWindows software to control a set of VME VO modules. As with the previously described controller, a top level computer display screen shows the operator the high level modulator functions, including general interlock status, high voltage power supply levels, and klystron support equipment status. Additional sub-screens can be brought up to turn on and adjust all of the modulator sub-systems, including the high voltage power supplies, pulse transformer bias power supply, thyratron auxiliaries, klystron magnet power supplies, klystron heater power supply, klystron vac-ion pump power supplies. Other features include software and hardware debugging routines and automatic data logging. Value 600 kV 870 A 14 ks 10 us
