Description
After the first three years of the LHC running the ATLAS experiment
extracted it's pixel detector system to refurbish and re-position
the optical readout drivers and install a new barrel layer of pixels.
The experiment has also taken advantage of this access to also install
a set of beam monitoring telescopes with pixel sensors, four each in
the forward and backward regions. These telescopes were assembled based
on chemical vapour deposited (CVD) diamond sensors to survive in this
high radiation environment without needing extensive cooling. This talk
will describe the lessons learned in construction and commissioning of
the ATLAS x Diamond Beam Monitor (DBM). We will show results from the
construction quality assurance tests, commissioning performance,
including results from cosmic ray running in early 2015 and also
expected first results from LHC run 2 collisions.
