BLM

Beam loss monitoring system (BLM) is used to monitor the beam losses. If beam interacts with the inner side of a beam tube, the lost particles hit the walls and create secondary particle showers, which can be observed and measured outside of the beam tube

  • plastic scintillators are very fast and suitable for all types of losses
  • the usage is recommended for loss rates up to few 10^7 counts per second
  • each detector has the same response function

  • based on plastic scintillator
  • 16 (18) locations along the HADES beamline
  • stand alone solution for LASSIE Data Acquisition System (HHT Dach)
  • fully FAIR compatible System
