Partial List of Viewgraphs

Title Page for the presentation Bringing Beauty to HERA
High energy physics at DESY/HERA
View of West Hall - comparison with previous year
Side view of the full HERA-B detector [Isometric View A (9/10/95)]
Another view of the HERA-B detector [Isometric View B (9/10/95)]
View near e-ring superconducting rf - comparison to previous year
Many components in the west straight section stay in place ("Bleibt")
but many components have to be moved (i.e. skew quadrupole shown
moves 133 m to right, "Von WR20 nach WR153").
The HERA-B detector dipole in the West Hall
Views of HERA-B target chamber - comparison to previous year
Views of HERA-B muon system in West Hall
HERA-B detector as seen by experiment and machine crew.
Schematic diagram showing changes in west straight section.
Comparison with new configuration (above) and old configuration (below).
Note only about 2/3 of west straight section is shown here.
Schematic diagram showing changes in west straight section.
Note reduced lever arm for the abort kickers.
Abort kicker solution. Note in spite of reduced kicker lever arm
same safety margin is achieved without having to make new kicker power supplies.
New magnets for HERA-B
Options for deflection compensation of proton beam due to HERA-B detector dipole.
Comparison of bump schemes.
HERA beam collimation (scraper) system with HERA-B optics.
Region between e-ring superconducting rf cavities where QR/QT quadrupoles placed.
Views from ring outside.
New placement for skew quadrupoles.
Laser path to e-ring polarimeter
Staged installation in West Hall
Views of HERA-B detector dipole. Note cutout in field plate and notch in pole-tip made
which are made to give room for e-ring vacuum chamber and field compensation.
Layout of field compensation magnet system (above) and final compensation magnet (below) upon arrival at DESY.
