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. Start of sequence on ISK4209d.dwg is at position [inches] x = 291.109" y = -214.168" Spencer: End of sequence on ISK4209d.dwg is at position [inches] x = 277.9285" y = 207.6593" this is 1.8" downstream of the centre of ILT:Q42.

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: (same for x,y - transverse) a = 0.416685 b = 5.229370 call TWISSMATCH( 1, 0.41665, 5.229370, 1., 1) call TWISSMATCH( 3, 0.41665, 5.229370, 1., 1) Olivier: Distance on ISK0141D.DWG from IRA:Q4 midpoint at x = -111.298" 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. 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.

Local inspection shows SID2 is a bit further than shown in IHE0571D.dwg, location updated based on visual inspection, location is approximate. Local inspection shows IV2 is much different that IHE0571D.dwg. Updated location updated based on visual inspection, location is approximate. Location updated based on approximate visual inspection. As per M. Alcorta, The IRIS IC windows are 10 mm x 10 mm squares. Local inspection shows IV2 is much different that IHE0571D.dwg. Updated location updated based on visual inspection, location is approximate. Locations below updated based on approximate visual inspection. As per M. Alcorta, This is the collimator that is used for alignment. It can be fully out, or can be inserted to provide a 5, 3, or 2 mm diameter circle on the beam axis. As per M. Alcorta,"the silver foil is where we freeze our H2 or D2 onto. we cool it to 4K and it is always present in the beamline no matter what we do. it has a small aperture just in front of it" Aperture is 5 mm diameter circle Ag foil itself is 4.5 um thickness. As per M. Alcorta, scintillator detector area is a 5 cm by 5 cm square.
