Commissioning results of the HZB quadrupole resonator
/ Kleindienst, Raphael (Helmholtz-Zentrum, Berlin) ; Burrill, Andrew (Helmholtz-Zentrum, Berlin) ; Knobloch, Jens (Helmholtz-Zentrum, Berlin) ; Kugeler, Oliver (Helmholtz-Zentrum, Berlin)
Recent cavity results with niobium have demonstrated the necessity of a good understanding of both the BCS and residual resistance. For a complete picture and comparison with theory, it is essential that one can measure the RF properties as a function of field, temperature, frequency and ambient magnetic field. [...]

High Current Energy Recovery Linac at BNL
/ Litvinenko, Vladimir N ; Beavis, Dana ; Ben-Zvi, Ilan ; Blaskiewicz, Michael ; Bluem, Hans ; Brennan, Joseph M ; Burger, Al ; Burrill, Andrew ; Calaga, Rama ; Cameron, Peter et al.
We present the design and the parameters of a small Energy Recovery Linac (ERL) facility, which is under construction at BNL. This R&D; facility has goals to demonstrate CW operation of ERL with average beam current in the range of 0.1 - 1 ampere, combined with very high efficiency of energy recovery. [...]

Measurement of the Secondary Emission Yield of a Thin Diamond Window in Transmission Mode
/ Chang, Xiangyun ; Ben-Zvi, Ilan ; Burrill, Andrew ; Hulbert, Steve ; Johnson, Peter ; Kewisch, Jorg ; Rao, Triveni ; Segalov, Zvi ; Smedley, John ; Zhao, Yongxiang
The secondary emission enhanced photoinjector (SEEP) is a promising new approach to the generation of high-current, high-brightness electron beams. A low current primary electron beam with energy of a few thousand electron-volts strikes a specially prepared diamond window which emits secondary electrons with a current two orders of magnitude higher.

Extremely High Current, High-Brightness Energy Recovery Linac
/ Ben-Zvi, Ilan ; Barton, Donald ; Beavis, Dana ; Blaskiewicz, Michael ; Bluem, Hans ; Brennan, Joseph M ; Burger, Al ; Burrill, Andrew ; Calaga, Rama ; Cameron, Peter et al.
Next generation ERL light-sources, high-energy electron coolers, high-power Free-Electron Lasers, powerful Compton X-ray sources and many other accelerators were made possible by the emerging technology of high-power, high-brightness electron beams. In order to get the anticipated performance level of ampere-class currents, many technological barriers are yet to be broken. [...]

Photoemission Studies on BNL/AES/JLab all Niobium, Superconducting RF Injector
/ Rao, Triveni ; Ben-Zvi, Ilan ; Burrill, Andrew ; Cole, Michael ; Hahn, Harald ; Kayran, Dmitry ; Kneisel, Peter ; Zhao, Yongxiang
Photoemission from all niobium superconducting injector is of considerable interest for the development of higher average current electron sources. In the past year, we have generated photocurrent from such an injector by irradiating the back wall of the 1/2 cell cavity with 248 nm and 266 nm laser beams. [...]

State-of-the-Art Electron Guns and Injector Designs for Energy Recovery Linacs (ERL)
/ Todd, Alan ; Ambrosio, Anthony ; Ben-Zvi, Ilan ; Benson, Stephen V ; Blüm, Hans ; Burrill, Andrew ; Calaga, Rama ; Cameron, Peter ; Campisi, Isidoro E ; Chang, Xiangyun et al.
A key technology issue of ERL devices for high-power free-electron laser (FEL) and 4th generation light sources is the demonstration of reliable, high-brightness, high-power injector operation. Ongoing programs that target up to 1 Ampere injector performance at emittance values consistent with the requirements of these applications are described. [...]

RF Design and Operating Performance of the BNL/AES 1.3 GHz Single Cell Superconducting RF Photocathode Electron Gun
/ Cole, Michael ; Ben-Zvi, Ilan ; Burrill, Andrew ; Hahn, Harald ; Kneisel, Peter ; Rao, Triveni ; Zhao, Yongxiang
Over the past several years Advanced Energy Systems and BNL have been collaborating on the development and testing of a fully superconducting photocathode electron gun. Over the past year we have begun to realize significant results which have been published elsewhere.* This paper will review the RF design of the gun under test and present results of its performance under various operating conditions.

Multi-Alkali Photocathode Development at Brookhaven National Lab for Application in Superconducting Photoinjectors
/ Burrill, Andrew ; Ben-Zvi, Ilan ; Dowell, David ; Pate, David ; Rao, Triveni ; Segalov, Zvi
In this paper we will report our progress on the development of cesium potassium antimonide photocathodes and their application in superconducting photoinjectors. Quantum efficiencies of 2-3 % at 545 nm, and 10% at 365 nm have been routinely obtained in the test stand, and electron emission uniformity, quantum efficiency at a variety of wavelengths, and lifetime under different vacuum conditions has been well characterized.
