the current coil status and which fit-ups the pre-measurements that
Station 1 - contains
photographs of the diagnostic loop terminations, and photographs of the
respective VVSA coils
Station 2 - contains
information on the A1/B1 fit and the respective drawings and various
spreadsheets and presentations on the C-C joint, assembly comparisons,
coil to coil test methodology, coil to coil interfaces, etc.

coil to coil assembly (e.g., A1/A2 alignment, gross and final fit
of coils, A1 bolt kit fit, A1 clearance issues, videos, SuperNut

coil lifts, iterations of the Field Period Assembly Plan, iterations of
the FPA-001 procedure, FPA sequence plans, MIT/QA plans, etc.

by NCSX and CERN/W-7-X personnel, photographs, trip report, etc.

Back Office Dimensional
Control Support of FPA
- contains data and code/methods used to size the shims for thee MCWF
Metrology Data used for shim sizing to date:
The Realignment Matrices (RM.A1 - RM.C6) are applied to the metrology
data of the coils to determining shim sizes within the sizeshims3.f
code. A check of this process is provided by Matlab routines under
Mark Smith's archival directory. The Realignment Matrices were
generated and documented under directory : "Job8205 - Dimensional
Station 2 Half Period Assembly - contains the
spreadsheet calculators deveoped to support the HP assembly operation.
Each calculator is fundamentally the same, howere improvements were made
with each use. Also there is data to be changed in each that is specific
to the joint being made up (ie A1-B1, B1-C1, ...)
Assembly of Half Period Over the Vacuum Vessel Segment
- This directory contains data and methods used to create the traces to
be mounted on the screens which the three lasers will follow during
station 3 - HP assembly over the VV.
Prior to assembly of th HP over the VV, the installed screen locations
(3 points per screen) are provided as well as the installed laser lines
(2 points per line). These coordinates are processed offline using the
scripts and codes defined below. The intersection of the lasers on the
screens is returned in the form of ProE ibl files of curves that are
then further processed by the CAD group (Tom Brown) and printed for
mounting on the screens. This was an iterative process as
indicated by the typical iteration for an email correspondence:
I've updated the assembly traces using your new coordinates for the
lasers and your revised screen locations.
Attached are some files in an zip file (renamed ...safe) giving the
traces of the lasers for assembly from the right (+Y) and the left (-Y).
The files ending in 11r are for the right side, those ending in 11l are
for the left side. The spreadsheets give the xyz data of the laser
traces and plots of them. They also give plots of the "Strap Lengths" on
the second worksheet for a fixed hook height. I used a height of 275 for
the left side, but reduced it to 255 for the right side to minimize the
total variation in length required. The required motion to has dropped
slightly to 25.85" inches with this scenario. Unfortunately, you cannot
live with one size fits all for the straps. To do that, the stroke would
have to increase to >31.1" (ie 36") . This assumes the hook height is
fixed during assembly at it's initial height and all vertical adjustment
is done with the actuators.
There are a bunch of ibl files as well. Files labeled trace01 thru
trace03 are the laser traces, trace04 is the CG and trace05 thru trace07
are the swivel points. I've looked at these in ProE and the Lasers do
track the lines.
I've done a check on the tension of the straps to make sure we are not
going into compression. The right side has one sling which drops to only
4% of the load and the left side has one that goes as high as 65%. I've
added some columns at the end of the second worksheet that calculates
how close to the edges of the triangle formed by the three support
points the hook/cg comes (in plan view) which is also an indication of
the opposite sling going limp. The right side gets to within 2". If we
don't know the CG that accurately, it could force us to move the support
points further apart.
Scripts and Codes:
The following scripts and codes are run on the UNIX platform using the
screen and laser coordinate data provide with the previously calculated
matrix transformation defining the assembly process over a number of
doall.path5tom3r15_right - script for doing assembly from right side
doall.path5tom3r18_left - script for doing assembly from left side
invkinematic2a.f - code to do inverse kinimatic calculations but can
also be used as it is here to just do the matrix transformations during
invkinematic2a.inp.path5tom3r15r - input to invkinematic2a.f for right
invkinematic2a.inp.path5tom3r18l - input to invkinematic2a.f for left
NOTE: The invkinematic2a.f code assumes assembly from right. For
assembly from left, the script assumes the user has imaged the screen
and laser point data to the right side and then images the results back
for the left side.
genleftscreen.f, genrightscreen.f - utility codes to help set up script
data using data supplied by CAD (Tom Brown)
lasertrace2.f90 - code called by doall script to do intersection
calculation of transformed laser line points with screens.
genpts_iblrev.f, genpts_ibl.f - utility codes run by doall script to
create ibl files from tables of points.
tension.f90 - code for calculating tension in each sling at each
step of assembly to verify stability of HP.
