Hello,
I've attached two vertex spectra of normalized yields measured on an
empty cell. In red, runs taken last week before the collimator went in.
In blue the same data with collimator in. No cuts have been applied.
The yield of reconstructed events decreased by more than 1/20. This is
a remarkable result !!
More to come when similar spectra will be made and compared for similar
data taken at different beam/slits position. Regards,
-- tancredi
