| Abstract |
The LANSCE drift-tube linac (DTL) accelerates the proton or H⁻ beam to 100 MeV. It consists of four tanks containing tens of drift tubes and post-couplers; for example, tank 2 is almost 20 m long and has 66 cells. We have developed 3D models of full tanks [1] in the DTL with CST Studio to accurately calculate the tank modes, their sensitivity to post-coupler positions and tilts, tuner effects, and RF-coupler influence. Electromagnetic analysis of the DTL tank models is performed using MicroWave Studio (MWS). The full-tank analysis allows tuning the field profile of the operating mode and adjusting the frequencies of the neighboring modes within a realistic CST model. Beam dynamics is modeled with Particle Studio for bunch trains with realistic initial beam distributions using the MWS-calculated and tuned RF fields and quadrupole magnetic fields to determine the output beam parameters and locations of particle losses.
