rookhaven photocathode rf gun
The Brookhaven Accelerator Test Facility (ATF) uses a photocathode rf gun to provide a high-brightness electron beam intended for FEL and laser acceleration experiments. The rf gun consists of 1-,' cells driven at 2856 MHz in 7r-mode with a maximum cathode field of 100 MV/m. To achieve long lifetimes, our photocathode development concentrates on robust metals such as copper, yttrium and samariu...
متن کاملHigh Power Testing of a 17 GHz Photocathode RF Gun
We report experimental high power test results on a high gradient 17 G H z RF photocathode gun. The 1 2 cell, π -mode, copper cavity was tested with 5-10 MW , 100 ns, 17.145 G H z pulses from a 24 MW Haimson Research Corp. klystron. A maximum surface electric field of 250 MeV/m was achieved corresponding to an on-axis gradient of 150 MeV/m. The gradient was verified by a preliminary electron be...
متن کاملDevelopment of a Novel Superconducting Rf Photocathode Electron Gun
Over the past year Advanced Energy Systems Inc. and Brookhaven National Laboratory have undertaken a program to develop a Superconducting Photocathode Electron Gun utilizing a unique cathode concept. The cathode concept is much simpler than many other approaches and should avoid many complications which might otherwise be encountered. This cathode concept does not utilize an insert of any kind ...
متن کاملFemto-seconds Electron Beam Diffraction Using a Photocathode Rf Gun*
One of the 21 century scientific frontiers is to explore the molecule structure transition on the femtosecond time scale. X-ray free electron laser (XFEL) is one of the tools now under development for investigating femto-second structure transition. We are proposing an alternative technique – femto-second electron diffraction based on a photocathode RF gun. We will present a design of a kHz fem...
متن کاملEXPERIMENTAL OPERATION OF A 17 GHz PHOTOCATHODE RF GUN
Initial operation of a 17 GHz RF photocathode electron gun has been achieved at MIT. This is the first photocathode electron gun to operate at a frequency above 2.856 GHz. Such electron guns have the potential for achieving record high values of electron beam quality. The 1.5 cell, p-mode, copper cavity was tested with 5-10 MW, 100 ns, 17.145 GHz pulses from a klystron amplifier built by Haimso...
