  1. My Activities at VECC during the last visit Hemen Kumar Kalita Gauhati University Special thanks to: Partha Pratim Bhaduri (VECC)‏ 1

  2. Outline: # First I've tried to read the mcpoints i.e. the information from the input files and get the position co-ordinates of the corresponding mcpoints and by looping over all the mcpoints generated the following plots: ●Distribution of mcpoints ● x vs y and r distributions. # Plots of Hit Efficiency per layer. (where Hit Efficiency =no. of Hits/no. of mcpoints)‏ # Plots of position resolution. 2

  3. All the plots are generated for 1K Pluto and embedded events 3

  4. For embedded For pluto 4

  5. For pluto For embedded 5

  6. Layer # 1 Front side of Layer # 1 For pluto 6

  7. x vs y dist. for layer # 1‏ For embedded 7

  8. Back side of layer # 1‏ Front side of layer # 1‏ For embedded 8

  9. For pluto For embedded events 9

  10. Layer # 1 Front side of Layer # 1 For pluto 10

  11. Layer # 1 Front side of layer # 1 For embedded events 11

  12. For pluto For embedded 12

  13. Layer # 1 Front side of layer # 1 For pluto 13

  14. layer # 1 Front side of layer # 1 For embedded 14

  15. For pluto Hit Efficiency per layer =no. of Hits per layer / no. of mcpoints per layer 15

  16. For embedded Hit Efficiency per layer =no. of Hits per layer / no. of mcpoints per layer 16

  17. Float_t delx = (x_mcp – x_h); // position resolution for x Float_t dely = (y_mcp – y_h); // position resolution for y Float_t delz = (z_mcp – z_h); // position resolution for z * ' *_h represent the position of the hit and * ' * _mcp represent the position of the associated mcpoint. For pluto 17

  18. For pluto 18

  19. Float_t delx = (x_mcp – x_h); // position resolution for x Float_t dely = (y_mcp – y_h); // position resolution for y Float_t delz = (z_mcp – z_h); // position resolution for z * ' *_h represent the position of the hit and * ' * _mcp represent the position of the associated mcpoint. For embedded 19

  20. For embedded 20

  21. Summary:- # Now I can read the information from the input files i.e. mcpoints, mctracks and extract track parameters from there. # Can generate all the plots for each layer i.e. station by station. # Can get the track ID and get the corresponding Pdgcode of the track. # Can calculate hit efficiency per layer and plot the graph # Can get the position resolution and compare the distribution of mcpoints with the associated mcpoints of the hits. 21
