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: http://lin12.triumf.ca/optr/ISAC/OLIS/3head/matlab/sy.f or http://lin12.triumf.ca/optr/ISAC/OLIS/SuperNanogan/sy.f 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. http://lin12.triumf.ca/optr/ISAC/OLIS/3head/matlab/sy.f 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.

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. 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. Danfysik 1987 L1 - QE-23 - #87124 Danfysik 1987 L1 - QE-11A - #87118 Olivier: See TRI-DNA-97-03, p. 11-12 for K1 discussion. No word on K2 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 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. 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).
