Charged Particle Beam Optics Programs by Urs Rohrer

<BODY> <SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript"> </SCRIPT> <NOSCRIPT> <CENTER> <H1>Particle Beam Optics</H1> Three useful <B>Particle Beam Optics</B> programs (mainly for charged particles like protons, electrons and mesons) are presented here. All three <B>Particle Beam Optics</B> codes are lagacy codes. But they are modernized and run under Windows, Linux and Mac OS-X with GUI support. </CENTER> </NOSCRIPT> <H1>Charged Particle Beam Optics Programs by Urs Rohrer</H1> <H4>Charged Particle Beam Optics: Graphic Transport Framework, Graphic Turtle Framework, Beam Tomography with Maximum Entropy</H4> <UL> <LI> <A HREF="trans.htm">Charged Particle Beam Optics Program 1: Graphic Transport Framework</A> </LI> <LI> <A HREF="turtle.htm">Charged Particle Beam Optics Program 2: Graphic Turtle Framework</A> </LI> <LI> <A HREF="ment.htm">Charged Particle Beam Optics Program 3: Beam Tomography using Maximum Entropy</A> </LI> </UL> The modernized version of the <B>charged particle beam optics</B> code named <B>Transport</B> consists mainly of the old CERN/SLAC/FERMILAB version coded in portable FORTRAN-77. It is mainly a Computer Program for Designing <B>Charged Particle Beam</B> Transport Systems. The best feature of this charged particle beam code is its superb fitting capabilities. A stochastic solver allows even to fit constraints without knowing the derivatives of the freed parameters (important for fitting with space charge).<BR> The modernized edition of the charged particle beam optics program named <B>Turtle</B> using Monte Carlo methods for ray-tracing charged particles through beam line systems also consists mainly of the old CERN/SLAC/FERMILAB version coded in portable FORTRAN-77. Up to 10 million particles my be histogrammed. Multiple scattering algorithms taken over from TRIUMF's REVMOC allow to track relatively accurate charged particles through collimators and targets.<BR> The Beam Tomography Program <B>MENT</B> based on a Maximum Entropy algorithm by LAMPF's Gerald Minerbo may also be used for computing and graphically displaying projected emittances of <B>charged particle beam optics</B> systems (beam lines).<BR> All three of these computer programs are very usefull for designing, investigating and/or debugging during commissioning of <B>charged particle beam</B> optical systems. Almost all of PSI's proton and muon beam lines have been designed and tested with Transport. Good agreement between measured beam optics parameters and design envelopes is usually observed. <UL> <LI> Program 1 for Charged Particle Beam Optics: Graphic Transport Framework </LI> <LI> Program 2 for Particle Beam Optics: Graphic Turtle Framework </LI> <LI> Program 3 for Charged Particle Beam Optics: Beam Tomography using Maximum Entropy </LI> </UL> </BODY>
