[Erd108] Interesting paper on GEM u-TPC in B field

[Kondo Gnanvo]

Hi all,
For those interested, please take a look at this paper on GEM in uTPC mode in B field.
Note that the drift gap is 5 mm here and in the paper they also observe a linear increase of the resolution with track angle as we are getting from the beam test and not exponential as expected from the rough simulation from Matt.
Another interesting point is the focusing / defocusing effect of Lorentz angle in B-field that we can use to our advantage for the double-sided thing-gap MPGD to correct for spatial resolution

Best regards
Kondo
