[Sbs_gems] [EXTERNAL] GEM current linearity studies so far

[Liyanage, Nilanga K (nl8n)]

Thanks Anuruddha, these are great. A few comments:


  1.  Remove the first and second points from the right hand plots: since these were used to determine the line, we should not get the deviation for these points
  2.  For the UVa XY modules, please discard the point at 1 uA; the GEM current at this setting is too small to be reliable, and this could be in the charge up region. Please use points 2 and 3 for the line for these modules

Best

Nilanga

Dear All,

Please find the GEM current linearity studies done so far with beam on.

They are under the conditions of:

  *   1 pass configuration with LH2 target
  *   2 pass configuration with LH2 target
  *   2 pass configuration with LD2 target

Please let me know if there are any questions/comments.
