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.

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. call TWISSMATCH( 1, -2.35, 98.0, 1., 1) call TWISSMATCH( 3, 0.14, 10.7, 1., 1) Danfysik 1987 L1 - QE-12B - #87115 Danfysik 1987 L1 - QE-7B - #87104 Danfysik 1987 L1 - QE-13A - #87130 Danfysik 1987 L1 - QE-12A - #87135 Danfysik 1987 L1 - QE-13B - #87134 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.

"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 Note that these are design parameters, but for now it is the only measured reference.

On IBP0500D.DWG, this corresponds to coordinates [inches]: x = 51.9199" y = 71.1069" 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.

Adjusted accordingly. Olivier: diag positions for FC5,SCD5 are placeholders to avoid negative drifts.

This device is not used in beam simulations.

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 is noted as a drift for reference.

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.
