Sept 23 2019 - re-referenced to drawings IIS0135D.dwg,
IIS0192D.dwg and ILE0173D.dwg
Olivier April 2 2020 - I found all EQ's with incorrect
lengths. I think this is from all the back and forth
with EQSkim. Odd, as we had agreed to put it in. I'll
correct the quadrupole lengths in ios_db1.xml, as it's
supposed to be the skimmer-less version. I'll add the
skimmer EQSkim (later) in ios_db1_skim.xml.

Olivier: IOS:FC6 position placeholder to avoid negative drifts.
Spencer: EMIT and FC6 from ISK4209.dwg, but swapped their positions
as clearly emit is actually before FC6, so locations are approximate.
Olivier: IV7 and all attenuators are to be considered
approximate. Changes made to IOS attenuators circa
2016 are not encoded in the Ray Dube drawing.
This is the OLIS 10x attenuator
This is the OLIS 120x attenuator
This is the OLIS 210x attenuator
This is the OLIS 3400x attenuator
Olivier: ordrevB was -156.97mm before Q9, I've modified it's position
accordingly - Q9 position changed Sept 23 2019 after re-measure.
(Spencer?) Q9 length changed from eletrical length to effective. See:

***************************************
Sequence ends on ILE0173D.dwg at coords [inches]:
x = 97.342"
y = -0.850
which is the same distance from the midpoint of Q9 from the old
deprecated measure above. This is the start of sequence ios_db10.xml
Olivier: Drawing referenced ISK4209d.dwg.
Quadrupole apertures verified.
Bender gap parameters verified.
Quadrupole polarity taken from above dwg.
From ISK4209d.dwg, the curved line segment within the bender
electrode has a length of l = 7.854" = 19.9492cm, which is consistent
for all benders in both the IOS:DB10 section and the ILT corner to the
RFQ.
Thus, the midpoint of the curved segment, at the optical center
of the bender path is at l = 3.927" = 9.97458cm from the point
at which the curved line begins on the drawing.
NOTE: ON ISK4209d.dwg, this sequence starts at (inches):
x = 260.685"
y = -183.743"
which corresponds to the top side of the blue, horizontal,
rectangular bar immediately below IOS:Q9, on the drawing.
Olivier: this sequence ends on ISK4209d.dwg at coordinates [inches]:
x = 291.109"
y = -214.168"
this point corresponds to the right hand side of the vertical blue
rectangle immediately to the left of ILT:Q33.
total path length s = 1182.2216mm
Olivier: Jan 31 2019, compared some distances to ISK4209d.dwg
found several discrepancies. Unclear where some of these were
referenced from.
Quadrupole optr tags and polarity have been obtained from above
source.
Update - Feb 14 2019: Quadrupole polarities in ILT seem to have
originally been coded in reverse. Polarities have been re-verified
against both isk4209d.dwg and Rick's original ilt-ira optr tune
at lin12.triumf.ca/optr/ISAC/RFQ_buncher/sy.f
Prebuncher remains to be modelled in opera-2D. Remains unclear
how to elegantly transition TRANSOPTR from DC to bunched. Will
have to get guidance from Rick.
For now, I've implemented a triple discrete RFGAP call for the
prebuncher. This is useful for longitudinal bunching, however
it's unclear if this will do a good job simulating the actual
prebuncher.

Corresponds to position on ARIEL drawing ART2080.dwg of:

Note that the units on ART2080.dwg appear to be messed up. To get an

**************************OLD******************************
Olivier: IRA:Q4 centerpoint is to be used for alignment
of RFQ vane mapping.
RFQ 2term field map original length = 760.1275cm, which starts
at the beginning of the radial matching section.
From Larry Root's bnd_rms4.f Relax3D simulation for the RMS,
quotes distance of 6 reference cell length (first cell) to
start of RMS, equal to 5.3250522cm.
From drawings ISK0141D.dwg, ILE0195D.DWG,
end point of IRA:Q4 coincides with beginning of RFQ tank
vacuum point. Thus, add dS = 10*5.53250522mm + 0.5*1.0*25.4 (half of
IRA:Q4 length), for dS = 68.0250522mm from midpoint of IRA:Q4
to start of RFQ vane/RMS.
drift distance from middle of IRA:Q4 to RFQ map centerpoint:
S_RFQ = S_Q4 + 0.5*25.4+1" + 10*5.53250522 + 0.5*10*760.1275
S_RFQ = S_Q4 + 3868.6626mm
Note that this is a single data point, from Larry Root,
which was done during development. There is still no hard
value for positioning of the RFQ vane, with respect to
a known reference point.
It will be critical to find this distance, with accuracy
and precision, if the model is to be trusted.
Olivier: Rotation by -45deg to accomodate tilted RFQ 4-vane structure.
From RFQ vane positioning measured back from MEBT:Q1/endOf_sequence,
this places the end of the IRA:Q4 to RFQ start drift position at
s = 6729.9224.
The twiss parameters at the RFQ entrance (beginning of radial matcher)
which produce an ideal match are as follows:
(same for x,y - transverse)
a = 0.416685
b = 5.229370

Olivier: Distance on ISK0141D.DWG from IRA:Q4 midpoint at

y = 2913.729"
measured to beginning of MEBT vacuum flange at:
x = -111.298"
y = 3221.523" (end of sequence point x,y)
is dY = 307.794" = 7817.9676mm
also note that the above point (-111.298";3221.523")
corresponds to the point, on IBP0436D.DWG:
x = 217.679"
y = 76.798", which is the start of the mebt_db0 sequence.
Olivier: Sequence starting point referenced to IBP0436D.DWG
at coordinates (inches):
x = 217.679"
y = 76.798"
This corresponds to the start of the vacuum flange on the
MEBT side, and agrees with both drawings IBP0436D.DWG and
on ISK0141D.DWG to (inches);
x = -111.298"
y = 3221.523"
this ensures the ilt_db33 sequence and mebt_db0 start at
a common reference point with no artificial drifts.

This device does not exist in EPICS at all, it is a foil carousel that is adjusted locally.
Olivier: Back-rotate by -45deg around optical axis.
At this point, MEBT quads go from being tilted by 45
to being "flat".
The bunch rotator is used to create a round beam spot
on the stripping foil, in addition to a time focus.
Thus, rotating the beam by 45deg (in transoptr) at this
location should not result in discontinuities in the
envelope.

in that reference however.
"Given that the anticipated vertical beam size in the dipole is +-5mm
= +-0.20in., we suggest that a value of K1 = 0.55 be used in TRANSPORT
calculations."
finally, the full gap is noted as (p.1) g = 2.250in. = 0.0572m = 5.72cm
