The damage caused in scintillating crystals by fast hadrons has been observed to present specific contributions, that are absent in a purely ionising radiation field. All the observed features point towards the creation of so-called "fission-tracks" in materials whose elements lie above the fission-threshold. In this paper we present visual evidence for the creation of fission tracks in Lead...
Future HEP experiments at the energy and intensity frontiers require fast and ultrafast inorganic crystal scintillators with excellent radiation hardness to face the challenges of unprecedented event rate and severe radiation environment. This paper reports recent progress in fast and ultrafast inorganic scintillators, such as LYSO:Ce crystals and LuAG:Ce ceramics for a shashlik sampling...
Increases in luminosity at the LHC will lead to higher radiation exposure of detectors located along the beamline. This problem is especially acute for the Zero Degree Calorimeters (ZDCs) in ATLAS, which are exposed to dosages on the order of 10 Grad/yr during p+p running. We have systematically studied the damage this radiation has caused in our current detector, while at the same time...
In the past crystalline inorganic scintillation material has played a dominant role in calorimetry in medium and high energy physics experiments. Future detector developments will have to focus on cheap, fast, and radiation hard materials in particular with respect to damage caused by hadrons. Developments have been directed towards scintillation materials with a lower effective nuclear...
