Description
The High Luminosity upgrade of Large Hadron Collider (HL-LHC) will increase
the LHC Luminosity by an order of magnitude increasing with it the density
of particles on the detector by an order of magnitude. For protecting the
inner detectors of experiments and for monitoring the delivered luminosity,
a radiation hard beam monitor is being developed. For ATLAS we are developing
a set of detectors based on poly-crystalline Chemical Vapor Deposition (pCVD)
diamonds and a dedicated rad-hard ASIC. Due to the large range of particle
flux through the detector, flexibility is very important. To satisfy the
constraints imposed by the HL-LHC, our solution is based on segmenting each
single diamond sensor into multiple devices of varying size and reading them
out with a new multichannel readout chip. In this talk we describe the
proposed system design including detectors, electronics, mechanics and
services and present preliminary results from the prototype ASIC and first
devices fabricated using the ASIC.
