Longitudinal tuning of the LAMPF 201. 25-MHz linac without space charge. [PARMILA code]

PDF Version Also Available for Download.

Description

After an accelerator is operational, the simulation models, used in the design phase to study perfect linacs or those with random errors, can be specialized to study the behavior of the actual machine and optimize its performance. This is being done on the Alvarez linac at LAMPF using the PARMILA model. As many of the actual measured physical parameters as possible were incorporated into the code, and it was necessary to include a more comprehensive treatment of the beam dynamics to make the model and experimental observations agree. For example, it is necessary to consider longitudinal and transverse phase space ... continued below

Description

After an accelerator is operational, the simulation models, used in the design phase to study perfect linacs or those with random errors, can be specialized to study the behavior of the actual machine and optimize its performance. This is being done on the Alvarez linac at LAMPF using the PARMILA model. As many of the actual measured physical parameters as possible were incorporated into the code, and it was necessary to include a more comprehensive treatment of the beam dynamics to make the model and experimental observations agree. For example, it is necessary to consider longitudinal and transverse phase space together in the calculations. The modifications to the model, the results of experiments that indicate the validity of the model, and use of the model to optimize the longitudinal tuning of the Alvarez linac are outlined.
