**Simulation Results for NLC-500 Parameter Set**

Andrei Seryi has generated 6 electron.ini, positron.ini files corresponding to 6 typical NLC-500 lattices with different random errors. See files here. Their format is (E, x, y, z, angx, angy) in units of (GeV, microns, microns, microns, microrad, microrad).

A Guinea-Pig simulation was then run by Mike Woods with 14787 particles using
input files "electron1.ini" and "positron1.ini" to generate the file
"beam1_IP.dat." Beamstrahlung effects were included. Takashi Maruyama's GEANT-3 simulation was then run
by Ken Moffeit to
transport the "beam1_IP.dat" file to the mid-chicane, generating the file
"beam1_chicane.dat"; no particles were lost
before the mid-chicane.

Additionally, a DIMAD tracking simulation of the extraction line has been done by Yuri
Nosochkov, using the same beam1_IP.dat
input file at the IP to generate the file "beam1_chicane_dimad.dat".

Below are 3 data
files, 3 Matlab routines to plot data from the 3 data files and 3 sets of standard plots for these 3 data files.

- beam1_IP.dat is the beam distribution file at the IP
- beam1_chicane.dat is the beam distribution at the mid-chicane using a GEANT simulation
- beam1_chicane_dimad.dat is the beam distribution at the mid-chicane using a DIMAD simulation
- lumi.dat is the distributions of particles that make luminosity at the hard collision
- beam1_IP_plots.m is a Matlab file to read beam1.dat and generate a set of standard plots
- beam1_chicane_plots.m is a Matlab file to read beam1_chicane.dat and generate a set of standard plots
- beam1_chicane_plots_dimad.m is a Matlab file to read beam1_chicane_dimad.dat and generate a set of standard plots
- beam1_IP.pdf is a pdf file of standard plots of the beam distributions at the IP (generated by Matlab)
- beam1_chicane.pdf is a pdf file of standard plots of the GEANT beam distributions at the chicane (generated by Matlab)
- beam1_chicane_dimad.pdf is a pdf file of standard plots of the DIMAD beam distributions at the chicane (generated by Matlab)

The format for the data files is:

i) beam1_IP.dat:
(E, x', y', z, x, y) in units of (GeV, rad, rad, microns, nanometers,
nanometers); z is the longitudinal co-

ordinate within the bunch

ii)
beam1_chicane.dat: (E, x', y', z, x, y) in units of (GeV, rad,
rad, cm, cm, cm); z is the location of the mid-chicane

iii)
beam1_chicane_dimad.dat: (E, x', y', z, x, y) in units of
(GeV, rad, rad, microns, nanometers, nanometers); z is the

longitudinal co-ord
within the bunch

iv) lumi.dat: (E1, E2, x, y, z)
in units of (GeV, GeV, nanometers, nanometers, microns); (x,y,z) are the
co-ordinates of the

hard collision

6 independent beam1_IP.dat (for outgoing beam electrons) and beam2_IP.dat (for outgoing positrons) that correspond to Andrei Seryi's 6 electron.ini, positron.ini files (corresponding to 6 typical NLC-500 lattices with different random errors) can be found here.

6 independent lumi.dat files that correspond to Andrei Seryi's 6 electron.ini, positron.ini files (corresponding to 6 typical NLC-500 lattices with different random errors) can be found here.

Distributions of pairs at the LUMON detector have been simulated by Takashi Maruyama for the NLC-500H parameter set. This was described in his recent talk at the ALCPG workshop held at SLAC in January, 2004. ASCII and n-tuple files of these pairs are located here. The pairs have been tracked through the 5T solenoid field to the detector at z=+-3.15 meters from the IP. Both headon (0mr) and Crossing Angle (+-10mr) geometries have been simulated. The ASCII files are pairs01_5tesla_0mr.dat and pairs01_5tesla_10mr.dat, while the PAW ntuple files are pairs01_5tesla_0mr.rz and pairs01_5tesla_10mr.rz. The file formats are (E, Q, x, y, z, u, v, w), where E is in GeV; Q=+1(positrons) or -1 (electrons); x, y, z are in cm; and u, v, w are the direction cosines. The files contain pairs corresponding to 1 bunch crossing.
