Suppression of Multipass, Multibunch Beam Breakup in Two Pass Recirculating Accelerators / Tennant, Chris ; Douglas, David ; Jordan, Kevin ; Merminga, Lia ; Pozdeyev, Eduard
Beam Breakup (BBU) occurs in all accelerators at sufficiently high currents. In recirculating accelerators, such as the energy recovery linacs used for high power FELs, the maximum current has historically been limited by multipass, multibunch BBU, a form that occurs when the electron beam interacts with the high order modes (HOMs) of an accelerating cavity on one pass and then again on the second pass. [...]

High Power Lasing in the IR Upgrade FEL at Jefferson Lab / Benson, S V ; Beard, Kevin ; Behre, Chris ; Herman-Biallas, George ; Boyce, James ; Douglas, David ; Dylla, Fred ; Evans, Richard ; Grippo, A ; Gubeli, Joe et al.
We report on progress in commissioning the IR Upgrade facility at Jefferson Lab. Operation at high power has been demonstrated at 5.7 microns with over 4 kW of continuous power output and a recirculated electron beam power of up to 800 kW. [...]

High Average Power Operation of a Scraper-Outcoupled Free-Electron Laser / Shinn, Michelle D ; Behre, Chris ; Benson, S V ; Bevins, Michael ; Bullard, Don ; Coleman, James ; Dillon-Townes, L ; Elliott, Tom ; Gubeli, Joe ; Hardy, David et al.
We describe the design, construction, and operation of a high average power free electron laser using scraper outcoupling. Using the FEL in this all-reflective configuration, we achieved approximately 2 kW of stable output at 10 um. [...]

Longitudinal Space Charge Effects in the JLAB IR FEL SRF Linac / Hernandez-Garcia, Carlos ; Beard, Kevin ; Behre, Chris ; Benson, S V ; Herman-Biallas, George ; Boyce, James ; Douglas, David ; Dylla, Fred ; Evans, Richard ; Grippo, A et al.
Observations of energy spread asymmetry when operating the Linac on either side of crest and longitudinal emittance growth have been confirmed by extending PARMELA simulations from the injector to the end of the first SRF Linac module. The asymmetry can be explained by the interaction of the accelerating electric field with that from longitudinal space charge effects within the electron bunch. [...]

A High Average Current DC GaAs Photocathode Gun for ERLs and FELs / Hernandez-Garcia, Carlos ; Benson, Stephen V ; Bullard, Don ; Dylla, Fred H ; Jordan, Kevin ; Murray, Chuck ; Neil, George R ; Shinn, Michelle D ; Siggins, Tim ; Walker, Richard L
The Jefferson Lab (JLab) 10 kW IR Upgrade FEL DC GaAs photocathode gun is presently the highest average current electron source operational in the U.S., delivering a record 9.1 mA CW, 350 kV electron beam with 122 pC/bunch at 75 MHz rep rate. Pulsed operation has also been demonstrated with 8 mA per pulse (110 pC/bunch) in 16 ms-long pulses at 2 Hz rep rate. [...]

Experimental Investigation of Beam Breakup in the Jefferson Laboratory 10 kW FEL Upgrade Driver / Tennant, Chris ; Bazarov, Ivan V ; Douglas, David ; Hoffstaetter, Georg Heinz ; Jordan, Kevin ; Merminga, Lia ; Pozdeyev, Eduard ; Simrock, Stefan ; Smith, Todd I ; Wang, Haipeng
In recirculating accelerators, and in particular energy recovery linacs (ERLs), the maximum current has been limited by multipass, multibunch beam breakup (BBU), which occurs when the electron beam interacts with the higher-order modes (HOMs) of an accelerating cavity on the accelerating pass and again on the energy recovered pass. This effect is of particular concern in the design of modern high average current energy recovery accelerators utilizing superconducting technology. [...]
