Here I am simply digitizing my notes from our visit to CERN 17~18 January 2017. They may not be perfectly linear or organized, but may be searchable. ==ISOLDE Hall Info== Safety shoes and hard hats are required for everyone. We need to buy our own in the future and bring them with us. The 'general purpose scattering chamber' seems to in fact be named the Scattering Experiments Chamber (SEC). Contact Joakim Cederkall at Lund University in Sweden joakim.cederkall@cern.ch (DK has collaborated with him before in 2012) Secondary contact olof.tendblad@cern.ch 2 meters downstream of SEC we see the SAND neutron detector array. Contact Ismael Martel at University of Huelva in Spain ismael.martel.bravo@cern.ch Array structure is on wheels, but needs to be moved before our experiment, presumably by someone from that collaboration Of course, we don't know after the SEC relocation from station 2 to station 3 that SAND will be installed in the same relative position or not SEC has eight (8) transverse ports evenly spaced about its circumference We need adapters to connect to this The nominal ISOLDE beamline pipe is 50 mm diameter Chamber itself is about 1 meter in diameter, about 70 cm tall. Shape is a cylindrical prism with hemispheres on top and bottom Calculated volume about 0.55 cubic meters Support structure is about 1 x 1 square meter footprint, about 125 cm tall 2 large-volume pumps in parallel. TMP: PTM 5400 ALCATEL CORP x2 Oil roughing pumps Edwards 12 x2 According to Karl, its pressure is in the low 10^-6 mbar region, but everything seemed off when we visited so cannot confirm precise value Presumably it requires the overhead crane to open it Not many people have the license Although we don't need to access it very often if at all Karl said they are arguing to install a small fixed crane for that purpose after relocation which wouldn't need a license SEC is being disconnected over the weekend (21~22 Jan) Alignment in ISOLDE Hall (not very sensible to write w/o diagram) POT1, POT2 are on the wall downstream of the beam lines POT3 and POTREX are on the beam-right side before it is turned and delivered to the target stations Geodetic survey points -- though we don't really know how they are used Downstream of station 3 (under construction) is XT03 which is a crosshair on the wall Presume it was used for alignment of the steering magnet base Bases are installed but the quadrupoles are still off to the side There is no port on the station 2 bending magnet to offer a straight line of sight down to the target station How was the alignment performed? We assume station 3 will be installed in a similar manner, unfortunately. Station 3 Expected to be complete by the end of February Station 2 HELIOS-type device will be installed at station 2 This is presently called ISS and is mainly being done by the Swedish group (Lund?) Footprints were drawn on the ground downstream of the present SEC point How much space will the fence to prohibit near-approach for B-field safety be? Distances around the stations From the target positions to the far wall is over 10m, though a lot of equipment and storage lines the wall area Beam-right wall from station beam-line 3 is about 180 cm 7 m to station 2 -> ~5 m between station 2 and 3 End of station #2 to the end of the SEC including the beam pipe is ~210 cm At some point, we must provide a list of items ot be imported and used so it can be approved by the CERN Safety groups ==Meeting notes with Karl Johnston== HIE-ISOLDE may begin physics around the last week of June (say 24~25th) A MINIBALL experiment is usually prioritized first, given the track record and existing infrastructure and experience. From the end of April there will be about 2 months of commissioning, ideally Though, in years past, the timeline was too tight and commissioning was basically not performed during this period They will start the cryogenics on Tuesday, 24th January ISS will start to be installed in May for about 3 weeks (? hand writing and detail of notes is poor on this point) Anytime in mid-March should be okay for the Edinburgh group to ship 59Cu is a candidate for an early run this year As soon as early July perhaps in an ideal world Encoding*: HTML ELCode plain Suppress Email notification Resubmit as new entry
