Description
Recently a start for the 100 TeV p-p Future circular collider (FCC) project was given. Earlier a proton energy increase up to 33/2 TeV began to be studied in the framework of the high-energy phase of the LHC upgrade. The energies of the secondary e± and γ will reach many TeVs in the high pseudorapidity regions at both FCC and HE-LHC. The point is that these e±, γ energies are high enough to give rise to the drastic increase of the e+-e− pair production and hard γ-emission probabilities in oriented crystals related with their synchrotron-like mechanism. The development rate of electromagnetic showers will increase and the length decrease, accordingly, allowing to devise principally new electromagnetic calorimeters (ECAL ) of reduced length. The radiation cooling phenomenon will also pronounsly manifest itself at such energies, additionally accelerating shower development and allowing to discriminate e+, e− and γ.
