Peter Black | Notes on iris install/operation | The iris mounts have 2 superimposed constellations of 3mm mounting holes on them that correspond to those of the S2 detector, however the 85x85 square is missing one hole and the 110x40 rectangle is rotated by 45°. Either constellation may be used. Fixing is intended with M3x16 bolts into 10mm standoffs used to attach the detector to its mount.
Electrical connection is by a 5 pin DuPont connector. A feedthrough with flying tail ribbon cable inside and M12 5 pin A-coded industrial sensor connector outside for each iris is supplied that should fin in the same flange as the cooling pipes. The connection between the ribbon and the actuator is to be made with the red coded wire on the ribbon to the yellow wire on the actuator such that the visible metallic portion on the pins is visible on the same side of both the male and female connectors when matted.
The control box needs to be mounted outside the chamber and the cables connected to the feedthroughs.
Power is supplied from the 12v PSU provided.
Twiddle knob to make iris open and close...
Notes:
- When handling the irises it is advisable to leave them in the open position.
- Don’t get grease on the irises or they will jam up and the actuator is strong enough to destroy them.
- The actuators contain a small quantity of grease, if this turns out to be an issue with the vacuum I will strip them down and degrease them.
- The controllers are “tuned” to the actuators so try not to muddle them up. (U and D)
- When not in use I would suggest removing power from them as they will potentially radiate some RF noise and just made your signals noisier.
- Datasheet for controller https://s3.amazonaws.com/actuonix/Actuonix+LAC+Datasheet.pdf
- They have been roughly set so that closed is a 20mmm orifice. If you need to adjust them open the control box and twiddle the pot next to the one next to the USB port (P2 right if you look at the data sheet). Cycle the power and to open and close it again, repeat until the desired orifice is achieved.
- Pins 1, 4 and 5 of X2 are the feedback potentiometer for the actuators so if you want to know where the actuators are (you think they may have jammed etc.) you can simply measure the voltage between 1 and 4 with the power on or the resistance with the power off

DK, PB | Notes from visit to CERN | 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 |

MD | Notes from visit of ISOLDE at 23rd May 2017 | Status of Beamline XT03 at HIE-ISOLDE:
Scattering chamber (1m*1m) will be put in place in next two weeks. They are just waiting for separate crane, which will be mounted on the wall.
(Reason is, that the roof crane can only go down in the middle for XT03, because it is the end of the hall)
The scattering chamber will take place at the gray surface with all tube connector.
The end of scattering chamber is ISO 100. Do we have the right adapter for the tube to connect?
The scattering chamber, with a lot of electronics inside, has a pressure of something E-06 mbar, so our pressure should fit well.
Our faraday cup was asked to have the possibility to monitor if we getting beam or not.
Behind the scattering chamber there will be a setup for Neutron Time of Flight experiment on C15 in the end of august and on 9/10Li in the end of October 2017.
The setup length will be additional 5-6 meters (close to left end of the poster/wooden box on picture).
Offline Setup:
Offline Setup next to parallel wall will probably not be possible due to the other setup, but there is at least 2-3m*4-5m space on the wall, where the beam line points to (corner). We just have to leave some space that people can access the crane ladder.
No specific time was discussed, because the current setup has to first installed.
Alignment:
The Tools are mounted at the wall (2 points) and are setup in the corner (stand from bottom). It is an electronic system, no further details from Karl, but contact has been established.
Beam Height:
Beam height is 1.75m. We will bring our own metal frame for support. What is our height (range) at the moment?
For Offline test we can have an alpha source.
Power plug: SWISS standard à need ADAPTERs
3 normal plugs per grounded access point (with C16 fuse). For offline testing we can easily use 1-2 access points, which would be enough.
Near the installation place at the beamline are also 2 access points, which we will share with the scattering chamber. In case we also use extension to the offline ones, although safety regulation allow no cables on the floor, so we always have to use cable guides above. (I´m not sure how they deal with power cables…)
Next point: cables guide are used, so we have to bring longer BNC cables and the other long ribbon cables.
No camacs crates are spotted at the moment by Karl, which we could use.
No OIL pumps are allowed anymore at HIE – ISOLDE. Our roughing pump and Turbo pump are working without oil, aren´t they?
Grounded crates??
Expectations:
They want to have a drawing of our setup (chamber including metal frame, crates, vacuum pipes, water cooling, … maybe add work place with PC)
And all the SAFETY Regulation papers should be prepared.
Important!!! Everything is temporary:
There are daily changes in the setup at XT03 with scattering chamber and neutron TOF setup in the next week and when ISS chamber will be installed, the odds and ends near the wall and the corner will hopefully disappear, so we will have a better picture how much space in the end will be there.
I will visit ISOLDE in the beginning of June again to see the progress.
Forgot to ask:
Any special placement for water cooling or can we still use shortest possible distance to chamber? |

CBH, DK | New Struts Installation | Struts arrived and were installed on Wednesday. The holes on one side of each of the struts to connect the wheels to were slightly too wide (11.5 cm vs 10.5 cm).
We've taken away part of the wheel holders and now they seem to be fitting in.
See attached photos:
1. First wheel with wide holder holes
2. Close up of work done
3. Second wheel with wide holder holes (on opposite corner of chamber)
4. Close up of work done
5. Wheel holder that was warped previously
6. Wheel holder that was warped previously, other perspective
7. What chamber looks like as of Wednesday afternoon
8. Lead sheets to make chamber a little bit more secure. |
