Sequence referenced to drawing ISK4585D.dwg at coords [INCH]:
x = 169.264"
y = 167.267"
Olivier: sequence ends on ISK4585D.dwg at coords [INCH]:
x = 198.108"
y = 152.253"
which is the start of ios_db1
Olivier: Referenced to drawing ISK4209d.dwg
Quadrupole lengths verified
Quadrupole apertures verified
Start of sequence is defined at points [in]
x = 297.535"
y = -64.219"
Feb 14 2019 - Quadrupole polarities were backwards.
Fixed.
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.
IOS:Q1 l = 99.72*mm, effl=48.92*mm
Switch ref: IIS0192D.dwg (note backward X-def'l - told Brian).
start coords defined at point [in]:
x = 42.9013"
y = 30.3312"
which is midpoint Q2 on IIS0135D.dwg
Switch ref: ILE0173D.dwg (note units incorrectly scaled by factor of 2. Div
everything by 2). Start coords defined at point [in]:
x = -16.054"
y = 25.303"
which is midpoint Q3 on IIS0192D.dwg
FC3 position approximate (410mm) - see ILE0173D.dwg
Olivier: regarding IOS:MB, see:

values (from Rick):
(SLAC-75 parameters):
ak1 = 0.317
ak2 = 2.0
(other parameters):
rho = 11.728" (bob's sy.f)
fullgap = 5.0800 cm
from my computations, taking an effective field boundary
of 0.998", I get (Olivier):
rho = 29.9887cm = 11.8066
rho*theta(60deg) = 31.4041cm
edge angle is 0 both in and out.

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:

DEPRECATED:****************************
Olivier: end of sequence defined on ISK4209d.dwg at coordinates [inches]
x = 260.685"
y = -183.743
***************************************
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

Q14-19 lengths changed from eletrical length to effective. See:
