Description
Bhabha scattered electrons are used to measure relative luminosity away from the IP. At SuperKEKB, this has been demonstrated using CVD diamond detectors at 4m from the IP. LGADs (Low Gain Avalanche Diode) have recently been tested as a potential alternative with the Lumibelle2 collaboration. This sensor has a much faster rise time, on the order of a nanosecond, but may be more susceptible to aging effects.
Future studies will focus on LGAD durability and performance over time and the annealing process which may restore performance. The studies done on the LGAD can verify suitability of this detector in the FCC for fast luminosity measurements as well as benchmark studies against SuperKEKB for finding optimal positions for installation along the beam pipe.
