List of Figures

1. Screenshot of a typical desktop when one uses gd1. The xterm in the upper right corner is used to edit the inputfile, the xterm in the lower right is used to feed gd1 with the inputfile, and the long xterm on the right side runs another instance of gd1. This second instance of gd1 is used to look-up the syntax of gd1's command language.
2. A drawing of the main cavity.
3. Screenshot of the desktop when the inputfile doris00.gdf has been fed into gd1. gd1 has popped up an instance of mymtv2 that shows the outline of the specified polygon.
4. Screenshot of the desktop when the inputfile doris01.gdf has been fed into gd1. gd1 has popped up an instance of gd1.3dplot that shows the generated mesh.
5. Screenshot of the desktop when the inputfile doris02.gdf has been fed into gd1. gd1 has popped up an instance of gd1.3dplot that shows the generated mesh. We now have only the eighth part of the total structure.
6. Screenshot of the desktop. gd1.pp has popped up three instances of gd1.3dplot, showing the electric field of the first three modes.
7. Screenshot of the desktop. gd1.pp has popped up three instances of gd1.3dplot, showing the magnetic field of the first three modes.
8. $E_z$ component of the first mode on the axis x=y=0. Since only the part of the structure below the plane z=0 is modeled, we only have direct information about the field below z=0. Clearly, the $E_z$-component is even with respect to the plane z=0.
9. The real part and imaginary part of the integrated voltage as a function of the position x. This plot has not been generated directly by gd1.pp, but has been produced by a simple shell-script.
10. Screenshot of the desktop when the default values in -wakes are used. The three instances of mymtv2 show the longitudinal and transverse wakepotentials at the position of the line charge, ie at the position (x,y)=(0,0). The yellow curves show the wakepotentials, the red curves show the used line-charge density. The upper left mymtv2 shows the longitudinal wakepotential, while the lower two mymtv2-windows show the transverse wakepotentials.
11. Screenshot of the desktop when the plots of wakes in a plane are requested. The two instances of mymtv2 show the longitudinal and transverse wakepotentials near the plane y=0.
12. The electric field as induced by a line charge traveling on the axis. The direction of the arrows indicate the direction of the field, and their size is proportional to the absolute value of the field strength.
13. The electric field as induced by a line charge traveling on the axis. The direction of the arrows indicate the direction of the field. Their size now is not proportional to the field strength, since we did specify that there should be a treshold value of "maxlenarrows= 2".
14. The technical drawing with the plungers, pumping hole and feeding loop.
15. Details of the technical drawing, showing the plungers.
16. An outline of the body of revolution that shall decribe the body of a plunger.
17. The plunger now has its axis showing in the right direction.
18. Screenshot of the desktop when the inputfile wPlunger00.gdf has been fed into gd1.
19. Screenshot of the desktop when the inputfile wPlunger01.gdf has been fed into gd1. Shown is a zoom of the interesting region near the plungers.
20. A plot of the real part and imaginary part of the accelerating voltage of the monopole mode in the cavity with plungers. Only the real part would be nonzero, if the symmetry plane at z=0 would not have been used. One can clearly see that the accelerating voltage no longer is independent of the x-position.
21. Screenshot of the desktop showing the matrialdistribution and the wakefield at some time. We cannot see the wakefield, since the material boundaries hide the field.
22. Screenshot of the desktop when we switched off the plotting of the material-boundaries.
23. Screenshot of the desktop when we switched on the plotting of the material-boundaries, but selected bbzhigh=0.
24. Screenshot of the desktop when we just said 'doit' in the section '-wakes'. gd1.pp has popped up three instances of mymtv2 that show the longitudinal and transverse wakepotentials at the (x,y) position of the line-charge. The yellow curves are the wakepotentials, and the red curve is the charge density of the line-charge.
25. Screenshot of the desktop showing the longitudinal wakepotential in the cross section of the beam-pipe where a beam can travel.
26. Screenshot of the desktop showing the longitudinal and transverse wakepotential near the plane x=0.
27. Screenshot of the desktop showing the longitudinal and transverse wakepotential near the plane y=0.
