Daid. Mirco | Trigger and scalars for 4.0 MeV/u | Tom et al. tuned the trigger this evening, before we began the runs. (Run 82, or Run 83??)
===TRIGGER===
Trigger condition is: E OR HI/ds
We count the CAMAC OR signals as follows: A,B
A: Which CAMAC module? Left to right, 1,2,3,4,5
B: Which module channel? This is the number engraved on the module by the LEMO output.
==E Definition==
All p-n sides of E detector:
RAL 109 discrim cable numbers: 4, 5, 7
=> Corresponds to CAMAC OR Numbers 2,2; 2,1; 3,1, respectively.
==HI/ds Definition==
All p-n sides of HI detector: 8, 9, 11
RAL 109 discrim cable numbers
=> Corresponds to CAMAC OR Numbers 4,3; 4,2; 5,3, respectively.
ds=Downscale; ds factor is 8 = 2^8 = 256
===SCALARS===
0: Ungated
1: Gated
2: dE (n-n) [Cable 3]
3: E (n-n) [Cable 6]
4: HI (n-n) [Cable 10]
5: Pulser
6: Clock
===DISCUSSION===
The n-n side of the E detector seems to be noisier than the p-n side. Thus the p-n side is used for the trigger logic, whilst the n-n side is used for the scalar.
However, there seems to be something confusing about using the p-n side for the true trigger but the n-n side for the scalars. It means we cannot compare the scalars self-
consistently to each other. That is, the gated or ungated signals do not have a strong correlation with the individual detector scalars. In principle if we have enough LEMO
cables and Fan In/Fan Out modules, we should simply propagate the p-n signals to both the trigger (when relevant, i.e. E detector) and the scalars alike. For now we don't
touch anything, though. |

ISOLDE 44Ti meeting notes
19 Jul 2018
==To be ordered==
*Entrance window foils, TBD
6um Ti from Goodfellow?
*Gas bottles at CERN - Helium and (likely) Argon.
ISOLDE might provide them, but they never did for N2 gas
Gas bottle will need a regulator (new or old one)
*Spanners to help repair water chiller leak.
We need the right imperial size (x2) for Swagelok.
Sizes? Email says 2x 9/16" but let's confirm
*High precision balance
No new updates. Do we really need it?
==To be repaired / replaced==
*Manual gate valve between SEC and Edinburgh chamber
Responsible: Peter, Daid, CERN Vacuum Team ...
The old one had a leak, likely from the O-ring
(Automated fast-acting gate valve could be required)
At some point, we may have to decide w/o input
Path of least resistance: fix existing one
(The old manual one should be around Peter's office...what's the beam pipe size?)
*Silena 7100 Quad Bias supply showed false readings during 59Cu exp.
Responsible: Daid, ...
Not yet repaired, Peter searches for manual
Alternative module was found and tagged for our use, needs testing
*ORTEC 474 TFA was returned to Edinburgh, owing to 10 V baseline shift
Responsible: Daid, ...
Useful for photodiode trigger. Take replacement back to CERN.
Tagged for repair.
Alternative module was found and tagged for our use, needs testing
*Teflon chamber feet stands
Responsible: Toby Fu
The original foot engraving diameter was too small, by mistake. The chamber could be shifted after alignment
But what are the design specifications?
EMAIL Mirco TO PICK THEM UP FOR US FROM ISOLDE
==Decisions==
*How shall we integrate the beam intensity delivered to target?
Gold foil w/ back-scattering to photodiode?
Needs foil, mounts for foil & photodiode. Other parts prepared.
Alpha scattering in SSDs is another option
*Photodiode degrader foil for isobaric check
Which Al foil(s) are prepared?
In Edinburgh or CERN?
What thickness is sufficient for 44Sc / 44Ti separation?
*Gas cell entrance window material / thickness
==Work==
*Decide beam energies
Responsible: Conor, Alex, Daid
1.2, 1.55, 1.88, 2.2 and 2.8 MeV/u were stated as available
*Model effect of beam spot size.
Responsible: Conor
~3 mm FWHM was achieved for 59Cu
*Gas cell
Responsible: Katie, Conor
Vacuum system is set up in Edinburgh, and He gas is available
He gas bottle needs a mounting support prior to use.
Everything is in Physics Stores
We can continue to investigate true leak rate, gas cell handling, assembly
Gas cell eventually needs to go to CERN.
Are we satisfied with the setup, or shall we get new parts?
(e.g. several new valves, ...)
*Chamber alignment
Responsible: Peter Black
Chamber is currently disconnected from the beam line.
Previously, we contacted the survey team to come assist.
*DAQ PC has any further issues to get on the network?
Responsible: Tom Davinson
(If PC is turned on, contact Ruchi as she would like some data.)

NB: Might damage piping during re-assembly
We need the right imperial size (x2) for Swagelok.
Sizes? Email says 2x 9/16" but let's confirm
*High precision balance -- no need to buy
We are welcome to use the one in the chem lab on 2nd floor
Just wear a lab coat, and don't move other people's stuff
*PPE (Safety)
Boots and hardhats for new members
==To be repaired / replaced==
*Manual gate valve between SEC and Edinburgh chamber
Responsible: Peter, Daid, Conor, Katie, ...
The old one had a leak, we don't know where
It's on top of Peter's PC in his office
Students can test in Edinburgh...once leak is identified:
Fix ourselves or send to Lesker?
*Silena 7100 Quad Bias supply showed false readings during 59Cu exp.
Responsible: Daid, ...
Not yet repaired, Peter searches for manual
Alternative module was found and tagged for our use, needs testing

Responsible: Toby, Mirco, Daid
The original foot engraving diameter was too small, by mistake.
But what are the design specifications?
(Mirco picked these up for us, so they are in Germany?)
*Chamber stand wheel struts
Responsible: Peter, Daid, ...
Original ones are damaged at the ends, and also too long
Maria suggested 120 cm. We measured ~121 cm opening towards garage
To make less top-heavy, we can add a lower shelf and stack weight on it
==Decisions==
*How shall we integrate the beam intensity delivered to target?
Total integrated current, with efficiency-calibrated Ge detector
Talk to Liam?
Gold foil w/ back-scattering to photodiode?
Needs foil, mounts for foil & photodiode. Other parts prepared.

*Model effect of beam spot size -- still relevant?
Responsible: Conor
~3 mm FWHM was achieved for 59Cu
*Gas cell
Responsible: Katie, Conor
Vacuum system is set up in Edinburgh, and He gas is available
He gas bottle needs regulator, that's it.
Gas cell eventually needs to go to CERN.
Are we satisfied with the setup, or shall we get new parts?
(e.g. several new valves, ...)
*Chamber alignment
Responsible: Peter Black
Chamber is currently disconnected from the beam line.

dk | To do list before main exp. - update from meeting 28th September | NB: This list may be incomplete!
CERN side:
Beam operators hope for a FC which can be automated at the end of SEC: Olof ?
Gain resistors (and other items) sent to CERN. Where are they? KJ has them? Check with Karl
w26 PC needs to get online. Contact Olof when we return to ISOLDE to confirm the network port is still free.
Daid. Need to register the device to CERN
Dry N2 bottle: ask Karl
Edinburgh side:
Iris automated controls and mounts: in construction. Add additional stop so doesnt close all the way. Peter
Cooling line chamber feed through: get spare. Peter
Get Al degrader foil for heavy ions (~13 um), mount on dummy frame etc. probably fine from store. Should get 15
um for highest beam energy. With lowest beam energy we might need to change the foil: Daid
Alpha spectral analysis: to be sorted. Daid, Claudia, Tom, Ruchi
Sort routines for dE-E plots, etc, for online analysis: Tom
Photo diodes x2 along with degrader foil: PCB for photodeiodes, PCB for photodiodes. extra holes for ladder. Peter
Target ladder config finalization: 2 photodiodes, collimator (what size, we have 3 mm and 10mm), Beam viewer,
We need to verify how many positions we have. Need at least 2 CH2 and 1 Carbon. Daid, Claudia
Extra ribbon cables are needed? need to check with calibration. Also need long ribbon cables
Beam viewer: see target ladder
Faraday cup SHV to SMA converter: Peter
Window port for front of chamber? Peter
Photographs and diagrams of experimental setup -- organized clearly for beam operators during tuning: add
technical drawing on elog.
Alignment -- 2 end caps and one target ladder mount for optics reflector (8 mm diameter?) For survey people. Peter
Adjustable feet to be produced for radial alignment: Peter / Toby
Contact CERN about date for beam connection: As soon as possible after 20th October. Talk to Karl/Olof.
Collimator at exit of SEC ? needs to be aligned. Ask what the other beamlines do - does olof have collimator
ahead of his chamber
Calibration of Target ladder positions. Peter / Daid
Email to Karl & Olof about:
- FC after SEC
- Parcel of gain resistors
- date for connection of SEC to our chamber
- collimator in front of chamber ?
- N2 bottle |

DK | To do / missing | Photodiode
Electronics
Foil mount (12 um Al seems okay, but check more carefully)
Beam viewing material
Previous order very delayed
==TDC data==
*Check for remaining LeCroy 622 quad logic unit
ask Stephan http://www.ph.ed.ac.uk/people/stephan-eisenhardt
*Conversion cables for CAEN V767 TDC input
*RAL ADC output split of ribbon cable
==SSDs==
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
Gain resistors for up to three dynamic range settings |

DK | Strut measurement request | For posterity
==========
Hi Ruchi,
Could you ask a friend for me to make a measurement with a ruler? I
attach a PDF you may send along. It shows a basic picture of the blue
chamber stand, a picture of the broken part, and an arrow with what I
need to know. Second page of PDF shows what kind of signage should be
on the items of interest.
The steel wheel mounts have two bolts which connect them to the
struts. We want to know the spacing between the *center* of one bolt
to the second bolt, so that we know the spacing to drill into the new
struts. There are 4 such steel wheel mounts, two on a pair of struts.
My guess is the value is something around 12 cm give or take. But I
need a precise value and I forgot to measure it in August.
The chamber stand is located to the beam left of XT01 (Miniball) in
ISOLDE hall, or it was ...
Cheers,
daid |
