LLNL X-BAND TEST STATION STATUS ∗

In support of Compton scattering gamma-ray source efforts at LLNL, a multi-bunch test station is being developed to investigate accelerator optimization for future upgrades. This test station will enable work to explore the science and technology paths required to boost the current monoenergetic gamma-ray technology to a higher effective repetition rate, potentially increasing the average gamma-ray brightness by two orders of magnitude. The test station will consist of a 5.5 cell X-band RF photoinjector, single accelerator section, and beam diagnostics. Detailed design of the test station including beam dynamics is complete, and will be presented with modeling simulations and future upgrade paths. The current status of the installation will also be discussed with future commissioning plans.
