Re: Field amplitude
Dear Didier, Thank you very much. What I mean is that the field amplitude of the gaps cannot be set arbitrarily since these field distribution may not be realized in the cavity. To exaggerate, for example, in the first gap, the field amplitude is set to 1 MV/m, and in the second gap, the field ampli...

Re: Field amplitude
Dear Didier, I still have another question. The field distribution depends upon the detailed cavity geometry. How do you know the relative electric field strength for each cell before the DTL design (the geometry of the cavity is unknown yet)? Is it entirely based on experience? Best regards, Warson

Re: Field amplitude
Dear Didier, Thank you again. Since the electric field is calculated cell by cell, can the electric field in the gap within a cell be solved using electrostatic method? For example, for Alvarez DTL, Dirichlet boundary conditions are set at both ends of the cell (at the center of DT), and the Laplace...

Re: Field amplitude
Dear Didier, Thanks for your answer. In the design process, does GenDTL input the geometry of the first cell into Superfish, calculate the electric field distribution of this cell , and adjust the geometry of the cell through multiple iterations to achieve the required E0 and synchronous phase? Then...

Field amplitude
Dear Didier, I'm a bit confused to how to set the field amplitudes for each cell initially. The field amplitudes will affect the acceleration of the particle and the arrival time to the cell centers. My guess is that GenDTL uses Superfish to compute the electric fields to get the field amplitudes. I...

Re: What boundary conditions did PICNIC use when solving the Poisson equation
Dear Nicolas, I'm also interested in the detail of PICNIC algorithm and thanks for your answer. However, I still have some questions to ask you. 1. What's the expression of the linearly varying charge density? Is it in the form of ax+by+cz, where x,y,z is the coordinate axes, and if so, how did you ...
