4 Introduction I a collection of programs for calculating static magnetic and electric fields and radio-frequency electromagnetic fields in either 2-D Cartesian coordinates or axially symmetric cylindrical coordinates. Getting Started with Poisson Superfish: The best way to learn about Poisson Superfish is to run the sample problems described in the documentation.

14 The ASTRA program package can be downloaded free of charge for non-commercial and non-military use.
15 Introduction I The Astra (A Space Charge Tracking Algorithm) program package consists of the five parts: 1. The program generator which may be used to generate an initial particle distribution. 2. The program Astra which tracks the particles under the influence of external and internal fields. 3. The graphic program fieldplot which is used to display electromagnetic fields of beam line elements and space charge fields of particle distributions. 4. The graphic program postpro which is used to display phase space plots of particle distributions and allows a detailed analysis of the phase space distribution. 5. The graphic program lineplot, which is used to display the beam size, emittance, bunch length etc. versus the longitudinal beam line position or versus a scanned parameter, respectively.
16 Introduction II Astra is written in Fortran 90 and runs on different platforms. The minimal form of a namelist is: & Name / only those namelist which are required need to be specified and they can appear in arbitrary order. a namelist parameters are specified in the form: name = Value Specifications are separated by a comma or a line feed. Character input (keywords and file names) has in general to be enclosed by quotation marks ( ). The input of keywords is not case sensitive. general only the first character(s) are significant (bold letters in this manual)
17 Definition of the initial particle distribution distribution file name should end with the extension.ini or with.zpos.run. zpos = four digit number & run = three digit number specifying the run number Mix different kinds of particles as an initial particle distribution input particle distribution program generator user written program output distribution of Astra (except Local_emit = T)
18 The first line = the reference particle Longitudinal particle coordinates, i.e. z, pz and t are given relative to the reference particle. 1= electron 2 = positrons Index 3 = protons and 4 = hydrogen ions 5 14 =user defined ratio of mass to charge state
19 status flags
20 Passive particles Particles with a negative status flag are either lost by some mechanism or not yet started. Passive particles are tracked as normal particles; But not taken into account for The calculation of internal beam parameters; emittance, size, etc. The set-up of the space charge grid The calculation of space charge fields
21 generator generator generates an initial particle distribution file. The input file for generator has to have the extension.in. The default file name is generator.in. The input file consists of a single namelist named INPUT.
22 1D distribution: uniform distribution
23 1D distributions inverted parabola (longitudinal) The inverted parabola distribution produces linear longitudinal space charge fields. Gaussian distribution truncated Gaussian distribution
24 2D distributions radial uniform distribution (truncated) 2D-Gaussian distribution
25 isotropic momentum distribution 3D distributions photo emission from a Fermi-Dirac distribution uniformly filled ellipsoid
26 CAVITY I RF, static electric and magnetic fields and fields generated by linear plasmas. cavity fields may be generated by analytical calculations, measurements or numerical codes. field table z-position (column 1 in m) & longitudinal on-axis electric field amplitude (column 2 in arbitrary units) The transverse field components are calculated from the derivatives of the on-axis field. The polynomial expansion extends to 1st order or 3st order. The polynomial expansion is perfect already in first order for a pure sine-like spatial wave.
27 CAVITY II Static electric fields: The name should start with DC or the frequency, Nue( ), should be set to zero. Static magnetic fields: 3D field map TE modes: the file name has to start with TE_. Dipole modes: 3D field map Traveling wave structures: The file name has to start with TWS. superposition of real and imaginary parts The transverse field are derived according to a 1 st order polynomial expansion least one RF period plus the input and output coupler cells file a first line is added For a beta matched structure a wave number has to be specified
