Description

Dataset of simulated trajectories for the standard  X10-Y13 optics of VAMOS++ large acceptance spectrometer operated at GANIL.

The trajectories were simulated using the standard magnetic ray-tracing code zgoubi [F. Méot, The ray-tracing code ZGOUBI,  Nucl. Inst. and Method. A 427, 353 (1999) doi:10.1016/S0168-9002(98)01508-3]

The description of the coordinates used can be found in [A. Lemasson and M. Rejmund, Fast trajectory reconstruction techniques for the large acceptance magnetic spectrometer VAMOS++, Nucl. Instr. and Methods A, 1054, 168407 (2023)]

The  X10-Y13 optics is the reference operation optics for the VAMOS++ spectrometer, where focalisation of reference trajectories with reference relative magnetic rigidity (Delta=1) is focalised at distance from reference target position (0,0,0)  of 10 meters in X coordinates and 13 meters in Y coordinates.

Descrption of the dataset : 

  • Number of Files : 12
  • Data Format : ROOT/Cern (https://root.cern/doc/master/) (TFile and TTree) 
  • Each Files contains dataset of trajectories with randomly generated in the specific phase space described in M. Rejmund and A. Lemasson, to be submitted) for the reaction point (XT,YT,ZT), angles (Theta, Phi) and relative magnetic rigidity (Delta) along with calculated path length (Path in cm) and focal plane coodinates (Xf in mm, Tf in mrad ,Yf in mm,Pf in mrad) at 760 cm from reference target point (XT=0mm,YT=0mm,ZT=0mm)
  • Total number of trajectories : 201439908
