Olivier: placeholder booster position. Booster originally in /acc
at s = 5500.00*mm, though likely placeholder. Moved back a bit
to avoid negative drifts. POSITION STILL NEEDS TO BE CONFIRMED
all EPICS PV's need to be verified for name
**************************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:

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

Olivier: I've changed endOf_mebt_db0 reference to being tank1 outer surface on IBP0500D.DWG. Therefore, it follows that
all values referenced in the DTL (this file) are referenced to the same point on IRF1002D.DWG. This places tank1 midpoint
s-coordinate at the middle of my DTL Tank1 opera mapping, which is also referenced to tank1 outer surface (on the MEBT:Q13
side). January 29, 2019
IRF1002D.DWG, tank1 start point X=51.1528"

NOTE: Sept 13, 2019 (Olivier): see TRI-BN-19-18 for langevin DTL quad fits
do not remove factor of 2 multiplying langevin tanh values.
The optr attribute scalX is the x-scaling of the pseudoLangevin function
defined as the interval over which original magnet surveys were performed.

from HEBT:Q6 to HEBT:Q10. Adjusted accordingly.

Olivier: XCOL8A actual position is (millimeters);
y = 5869.6426mm
producing an s value of (mm):
s = 6086.0751, which places it within DSB:MB0 - not doable
in transoptr, so device was moved back. This device is not
used in beam simulations.

Olivier: Apr 11, 2019. This sequence may be deprecated
due to lack of tunables. I've amalgamated this sequence
in hebt_db9.xml, which starts from the end of sequence
hebt_db0 and drifts to HEBT:Q9. The location of the prague

Sequence starts on IHE0281D.DWG at coordinates [millimetres]:
X = 1403.9468mm
Y = 6007.5647
which is the end position of sequence hebt_db0. Note, hebt_db0 ends
at coordinates, on IHE0281D.DWG:
X = 1403.8054mm
Y = 6007.5647mm
there is a slight misalignment between the on-axis line defining the
beam axis on IHE0281D.DWG producing an x-coordinate alignment error of:
dX = 1403.9468mm - 1403.8054mm = 0.1414mm, or 0.0141cm, considered small
given the optics of the Prague magnet, however this should be checked
on TRANSOPTR - how sensitive is the envelope to adding a drift of 0.0141cm?
Olivier: Prague magnet (HEBT1:MB0) field indices need to be verified.
Prague magnet s-position of 1533.6958mm is the length from sequence start
to mid-point of arcline through prague trajectory. Arclength of Prague magnet
is l = 2414.6134mm
Olivier: apr24 - note theta used to be -90deg and entredge/exitedge were erroneously
set to 45deg each (without units), which:
1. gave wrong entry conditions (the edge angle is 0),
2. produced a numerical error as the 90/2 entredge/exitedge didn't have units.
