Claudia | Alpha Calibration | Run 1-10 Test
14 September 2017
Run 11 Start 18:16 (CERN time)
Faults:
adc#2 7,8 missing segments (n+n side dE)
adc#3 19 low gain (p+n E)
some strips have no noise but maybe that is OK.
Run 12 Start 11:50
Pulse switched on halfway through
Run 13 Start 12:08
Pulser on
ADC spectra:
#1 ch0 bad resolution (also pulser)
#2 ch7 ch8: no alphas, pulser there
#3 ch0 low gain, ch24 low resolution
#4 ch 7 low gain only for alphas (not pulser)
TDC missing: ch 32,80,120,123
Not understood yet: 1mm detector has peak at ~1.5 MeV @ adc#3 ch20-30 (with ALL alpha events when visible , 24 looks very distorted); not visible in ADC#4 (n+n) no alpha in ADC#6 although segment. |

dk | discussion with beam operators | CERN side
Faraday cup at the end of SEC, ideally with automated control to insert and remove
Edinburgh side
Photographs of chamber, diagrams, measurement, nicely organised
FC output from SHV to SMA, to input to CERN preamp
Beam viewer scintillating min beam intensity?
Irises to protect SSDs are essential since the beams will be tuned for energy case by case and not at once.
Collimator sizes for the target ladder?
Window view port to confirm iris settings?
Photodiodes should be on the opposite side of the target ladder from the collimator. |

E detector: 3080-23, 1012 um thick, V_d=110; V_o=350 V

How to protect the S2s during beam tuning?
Can the ISOLDE operators easily restore beam optics settings or not?
(Determines if we can do all the beam tuning at once or if we have to separate them)
Controlable iris aka Star Wars door -- contact Simon Fox at York
Dynamic range of the preamps is only maximum 200 MeV, so we need a foil to degrade the heavy ion energy

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? |

Tue Mar 14 10:57:20 2017 |
Claudia | Meeting Edinburgh 14 March 10 am 2017 | 1) DAQ
We have 192 channels to DAQ working. Mirco will test the silicon detectors with an alpha source in the next 2 weeks.
2) Vacuum
In the moment we reach 6E-6. There are still 2 tiny leaks. There will be an extra turbo for the upstream beam line which should improve the vacuum for ISOLDE purposes.
We need to check how fast we can pump down as might need to open the chamber between tuning and beam time (detectors need to be protected from tune beam).
3) Alignment
Alignment of the sample positions can be done here (Mirco/Peter). Claudia will contact Karl about a survey team for alignment at ISOLDE. Then we can talk to them directly.
4) Shipping
We aim to ship the setup to CERN by the end of March. We will try to go over to CERN for initial setup middle of April (to be confirmed with Karl)
5) Equipment needed from CERN
Claudia will ask Karl about availability of a CAMAC crate and 2 NIM bins.
6) Safety
Peter will order safety boots and hard hats.
Those who do not have ISOLDE access need to attend the ISOLDE radiation protection course.
7) Availability for Preparations
Tom not here: 25 March - 3 April, 25 April - middle June
