![]() ![]() The prototype cryomodule was used to verify alignment, electromagnetic performance, frequency tuning, cryogenic performance, low-level RF control, and control of microphonics. Civilization VI offers new ways to interact with your world, expand your empire across the map, advance your culture, and compete against history’s greatest leaders to build a civilization that will stand the test of time. Two of the 6-cell cavities were equipped with helium tanks, tuners, and input coupler and installed into the cryomodule. more » A prototype cryomodule was fabricated to test 2 cavities under realistic operating conditions. The 4-cavity cryomodule could be used for acceleration of ions in a linear accelerator, with focusing elements between the cryomodules. A rectangular cryomodule was designed to house 4 cavities per cryomodule. Coupled resonator model parameters and various measured parameters for the 805-MHz linac are = at the design field (accelerating gradient of 8 to 10 MV/m). Selected results from the theory of chains of coupled resonators are given. ![]() The section on field distribution measurement includes results of research on measurement procedure and theory and observations confirming the low-power stability of field distributions for a three-year period. Techniques for frequency measurements and for beadpull measurements of field distribution are discussed. Tools for tuning by dinging, nose-stretching, and septum bending are described. The steps of the tuning procedure are then examined in detail. An outline of the fabrication and installation process is given, showing how the tuning operations were interwoven with the fabrication steps and indicating the relation of tuning to other installation and check-out activities. Since this was the first proton linac of the side-coupled type ever built, it was necessary to develop new techniques and instrumentation for structure tuning. Civilization VI is the newest installment in the award winning Civilization Franchise. ![]() In the course of construction of the 805-MHz linac, it was necessary to set 10,000 resonant cavities to precise frequencies and to check, and in some cases, to adjust the field distribution along the beam axis of the 104 rf tanks composing the linac. ![]()
