Each month's notes are attached.  Unfinished business naturally carries over to the next month.

This elog will be updated with new notes as necessary.

NB: These are the notes composed *prior* to the meeting, thus do not include any suggestions or corrections.

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.)

ISOLDE 44Ti meeting notes
28 Aug 2018

==To be ordered==

*Entrance window foils, TBD
  3um Ti from Goodfellow?  Is it light-tight?

*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.
  *FIRST CHECK VACUUM, CHILLER!*
  	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

*ORTEC 474 TFA was returned to Edinburgh, owing to 10 V baseline shift

  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.
  Alpha scattering in SSDs is another option

*Photodiode degrader foil for isobaric check
  10, 15, 20 um Al are prepared at CERN, 2 blank frames in Edinburgh
  What thickness is sufficient for 44Sc / 44Ti separation?
    (...or other suspected contamination...)

  How many targets can fit & what should they be?
    3 mm collimator

  Karl mentioned the possibility of a beam test.

  Previous beam was 44Ti+13.  40Ar may be a good pilot?

*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.
