List of Figures

• Top view of the beam line from the exit of the main linac to the interaction point (IP) at TeV.
• Original idea of a muon attenuator. Two iron pipes are magnetized axially in opposite directions for both charged muons, which can be trapped, where the 120m length of the iron pipe corresponds to a mean range of 250GeV muons.
• Number of electrons to produce one muon which reaches the IP.
• Horizontal(6) and vertical(40) beam envelopes through the last bending magnet and five final focus quadrupole magnets(QC1,QC2,QC3,QC4 and QC5). The maximum divergences of the synchrotron radiation are also drawn by arrows.
• Profiles of the synchrotron radiation at QC1;right figure shows the magnified view around the center of QC1. The profile at the center accompanies the in-coming beam. The two right-hand side ones are passing through QC1 of 2.2m long after a collision with a 8mrad horizontal crossing.
• Electrons and positrons scattered by beam-beam interaction at IP. The vertical and horizontal axes denote the scattering angles in the vertical and horizontal directions, respectively. The left- and right-hand figures show the distributions of the positrons and electrons, respectively, downstream of the electron beam. Since the positrons have the same sign charge as the in-coming (positron) beam, they are scattered by larger angles than the electrons.
• Schematic view of the interaction region for 0.5TeV.
• Particles of pairs simulated by JIM based on GEANT3, where the solid and dotted lines are electrons/positrons and photons, respectively. The statistics corresponds to 1/100 of a bunch crossing for a display purpose.
• Number of hits detected in the detectors as a function of the radial distance for 10 bunch-crossings, where those produced by secondary particles are indicated by solid circles.
• Number of tracks creating the hits in the previous figure as a function of the radial distance for 10 bunch-crossings, where those produced by secondary particles are also indicated by solid circles.
• Angular distribution of hits on the first layer of the vertex detector for 10 bunch-crossings.
• Transverse distribution of secondary particles at z >1.6m for 10 bunch-crossings.
• Hit distributions observed at two disks of the beam profile monitor at z=1m for 10 bunch-crossings. BM-2 is behind BM-1, as viewed from the IP.
• Energy deposits observed at the beam profile monitor for 10 bunch-crossings. The solid and dotted lines are for the total and secondary particles, respectively.
• Distribution of hits whose energy deposit exceeds 70keV, as observed at the two disks of the beam profile monitor at z=1 m for 10 bunch-crossings.
• Angular distributions in 4.5 < r < 5.5cm for energy deposits of more than 70keV, observed at two disks of the beam profile monitor at z=1m for 10 bunch-crossings.
• Luminosity spectra calculated by the empirical function (histogram) and CAIN (solid circles).
• Luminosity spectra calculated by the generator (histogram) and the function (solid circles).
• (a) The luminosity-spectra weighted by the Bhabha cross section, without (with) the 1% uniform beam-energy spread, which is shown by the solid (dashed) histogram. (b) The spectra calculated by the acollinearity angles of the Bhabha events, where no entry above =500GeV exists by definition.
• Luminosity-spectra as measured by the acollinearity angles of the Bhabha events. Various angular resolutions of measuring the Bhabha scattered particles are considered. Solid, dashed and dotted histograms correspond to angular resolutions of =0(perfect), 3mrad and 5mrad, respectively.
• Luminosity normalized by the nominal one at GeV as a function of in two angular regions of (open circles) and (solid circles).
• Luminosity normalized by the nominal one at GeV as a function of the minimum polar angle to be measured for various angular resolutions.
• Log-likelihood distributions of the e-samples as a function of (a) and (b) , where the parameter was varied for 10% relative to the nominal value, while the other was fixed to the nominal value and vice versa.
