- Shashlik (physics)
In
high energy physics detector s, shashlik refers to a pile of alternating slices of absorber (e.g.lead ) and scintillator materials (crystal or plastic) used incalorimetry . [ [http://rkb.home.cern.ch/rkb/PH14pp/node19.html Calorimeter ] ] The absorber has a small interaction length, so that a particle radiates energy in a short track. The scintillator material produces visible light when transversed by the particle's radiated energy. This occurs with anelectromagnetic calorimeter , in the form ofphoton s and/orelectron +positron pairs. The energy of the particle may be then measured by the intensity of scintillation light produced by the various scintillator slices. An example detector that uses a shashlik electromagnetic calorimeter is theLHCb detector. [ [http://lhcb-calo.web.cern.ch/lhcb-calo/html/TDR/calo_tdr/node48.html LHCb calorimeter technical design report] ]This type of calorimeter was likely named after the
shashlik , a popular form ofshish kebab sold by street vendors in the formerSoviet Union by the Russian and Ukrainian scientists who first proposed it. [http://www.intas.be/catalog/92-0024.htm]References
