Historical Documents
- Possible cell- and layer-counts, for all-stereo or alternating superlayer chamber designs
- Summary of arguments for and against all stereo versus axial-stereo superlayer designs
Hex2 Design Information
| hex2.iso+pot+resol.edge.ps | Plots showing isochrones, equipotentials, and equi-resolution cell boundaries for edge cells of a superlayer |
| hex2.iso+pot+resol.incell.ps | Plots showing isochrones, equipotentials, and equi-resolution cell boundaries for inner cells of a superlayer |
| hex2.bounds.ps | Plots of DCA vs track entrance angle for equi-drift-time intervals up to the cell maximum, for the 4 cell layers of a superlayer |
| hex2.all.ps | a) Wire (hole) map in this simulation b) Isochrones of cells within and across superlayer boundaries c) Equipotentials for cells in a superlayer d) DCA vs track angle at equi-drift-time intervals for superlayer cells. e) RMS spread of DCA for track entrance angles +-30 deg to radial direction, as function of DCA. f) Expected resolution vs DCA when using a common t2d function spanning a range of track entrance angles |
| hex2.f and wout.f | Fortran source code for generating hex2 cell patterns |
| layradii.list | Ascii file containing wire locations, stereo angles, twist angles; modified 10/11/99 so that distances to stereo wires are in the plane perpendicular to the wire |
Endplate Hole Pattern
| wedge.f | Fortran main routine used to generate the endplate hole patterns, and corresponding DXF, list, and ps files |
| wedge_fp | Hole pattern of 1/16th sector wedge of front endplate at +z side (outside view), in dxf, autocad dwg, text, and postscript formats |
| wedge_fm | Hole pattern of 1/16th sector wedge of front endplate at -z side (wire side), in dxf, autocad dwg, text, and postscript formats |
| wedge_rp | Hole pattern of 1/16th sector wedge of front endplate at +z side (wire side), in dxf, autocad dwg, text, and postscript formats |
| wedge_rm | Hole pattern of 1/16th sector wedge of front endplate at -z side (outside view), in dxf, autocad dwg, text, and postscript formats |
Garfield Results
| contours+0cm_mag.ps.gz | Garfield isochrones and drift lines for all 40 layers in a magnetic field at the z=0 cm |
CMM Measurements
| GeomCorrection.txt | Corrections for wire locations, to be added to nominal geometry |
| WireLocation.xls | Excel spreadsheet containing CMM results; First worksheet is the CMM data; second contains adjustable overall parameters, such as chamber length, endplate deflection, relative twist, etc; third contains the calculated locations at both ends of the wire, nominal geometry, and resulting offsets, all calculated from CMM data and adjustable parameters |
