Tools & Codes

Baseline Calculation and Geographic Tools

• Some c to calculate the baseline between various accelerator sites and possible detector locations.  It also calculates the angle from the earth's surface from the accelerator to the detector.  It's pretty basic at the moment, but may improve with time.  Note that the latitude and longitude of both places are required.  These can be determined as follows:
  • The GEOnet Names Server will give you just about anywhere, but only to the nearest minute.
  • The UK Street Coordinate Converter translates from UK postcodes to latitude and longitude.
  • Zipinfo does the same for zip codes in the US.
• Peter Gruber's maps and baselines page, including coordinate data for many sites and Mathematica notebooks for calculating efficiencies.  This should be combined with the Scoping Study GLoBES database to calculate the physics reach.

Magnetic Field Calculation

• SolMap generates fieldmaps for systems of solenoids that are coaxial (as used in the muon front-end) or freely placed in 3D (as in certain ring coolers).
• BField calculates the field of arbitrary polygonal dipole magnets with high accuracy, point by point, by using an analytic expression for fields on the mid-plane.
• Superfish is a 2D code for calculating static magnetic and electric fields and radio-frequency electromagnetic fields in either Cartesian or cylindrical coordinates.

Tracking Codes

for Accelerators and Beamlines

• The ESME RF tracking program.
• TRANSPORT: a beam transport design code.
• TURTLE: a beamlines and spectrometer code. 

for FFAGs

• Zgoubi is used for accurate FFAG tracking and multi-turn beam dynamics through various sorts of magnets.
• Shinji Machida also is developing a code that has been used for FFAG error studies and emittance blowup effects.  E-mail for details.

for Targetry and Cooling

• The MARS Monte Carlo code for electromagnetic and hadronic shower simulation.
• GEANT4, a popular physics code with field tracking and interaction with materials.  Has many alternative options for physics fits/models.  Comparison of these with MARS15 for target work can be found in UKNF note 30.
• The two programs used for simulation studies of ionisation cooling:
  • ICOOL (also has extensive accelerator options)
  • double precision Geant 3 (DPGeant).

Physics and Detector Tools

• GLoBES is a comprehensive simulator of the physics performance from combinations of baselines and detectors.  It produces sensitivity plots of parameters like θ₁₃ and δ_CP.

You may be able to find out more about physics tools from the phenomenologists.

Miscellaneous

• The Muon1 distributed project for front-end optimisation, a background task your computer can run to help optimise this part of the neutrino factory.
