CALCULATION OF DRIFT-TUBE DIMENSIONS IN LINAC INJECTOR FOR THE 7 GeV HARWELL PHOTON SYNCHROTRON

Technical Report ·
OSTI ID:4226248
The dimensions of the drift tubes in the linac injector for the 7 Bev Harwell proton synchrotron (NIMROD) have been computed by finding, by an iterative method, that geometry of each unit cell in turn which will cause a reference particle to arrive at the center of each accelerating gap at an r.f. phase of -30 deg . The Laplacian potential was found by an approximate analytical method and by a relaxation method, the latter being superior. The equations of motion were integrated numerically by a method which uses the potential directly instead of the derived field. (auth)
