Query: TAC Proposal for Fundamental and Applied Research: Linac-Ring Type
  Phi-Factory   Main parameters of linac-ring type $phi$-factory proposed as the part of the
Turkic Accelerator Complex (TAC) in the framework of ATAM Science Sity Project
are discussed. Two sets of parameters, corresponding to E=130(260) MeV for
electron linac and E=2000(1000) MeV positron ring, are considered. It is swoun
that, in principle, L=10^(34)cm^(-2)s^(-1) can be achieved, which is more than
an order exceeds the design luminosity of the DA$Phi$NE. Parameters of the FEL
based on electron linac and synchrotron radiation sources based on the positron
ring are estimated.
