10/11/17: 00:03

switch target ladder to Pos #5: 82.44 mm

Carbon foil C_09 in place
(similar thickness as CH2_30+25, as used before)

Ready for beam coming back.

Fitting those half life data more reasonably... fitted the decay curve with y=a*exp(-b*t)+c to all the data points, comes up with t1/2=(85.8+/-2.6)s

--original email text--
Using Claudia's code, I added a layer of Al foil before the heavy ion
silicon detector.  The attached plots correspond to the heavy ion
portion of fig 3(a) in the proposal.  Thus it only uses ground-state
transitions and doesn't account for geometry or efficiency etc.  I opt
to show only the highest and lowest beam energies for each simulation.

As I said before, something between 10 and 20 um of Al was likely to
be the correct choice, which is confirmed.  10 um is almost to thin to
guarantee the signals are below 200 MeV, while for 20 um we start
having issues of detecting the lowest energy recoils for the low
energy run.

We can discuss the selection in more detail at the next meeting, but
most probably we can just use some kitchen foil, adopting whatever its
thickness of 13 to 15 um depending what we find.

The attached file starts with no degrader, then adds 10 um Al, and 1
um Al steps up to 20 um.

--Updated 2 Oct to include 5 um ~ 10 um--

As ~185 MeV is the maximum energy, but the gain resistors may vary by up to ~10%, then the 'maximium safe energy' is about 160 MeV.  This we can get for the highest energy run 
with 15 um Al (we have it in stock); however, then the lowest energy case becomes about 30 MeV, or less than 1 MeV/u, which may be an issue for straggling etc.  So we will 
prepare two foils, as it is seen even for the low energy beam, it comes almost to 190 MeV without a degrader foil.  In fact, any foil thickness between 5 ~ 10 um may be okay 
(we have 8 um in stock).  

Using also all 5 energies (212, 236, 260, 277, 295) then we see that the two lowest energies are okay for 8 um foil, and the three highest energies are suitable for 15 um foil.

NB: 19 Oct I deleted 15 um (previously attachment 2) and now it is attachment 8.  

Note that the beam energy order (right to left, left to right) differs between the first PDF and the second two.

--4 Oct--
Existing 8um Al foils are not the right size.  Check 6 um and 10 um in detail, as we have more stock of these two.  Attached.

--12 Oct--

Attachments 5-7 show the 59Cu energy after the degrader foils for elastic (12C,12C) scattering.  Foil thicknesses are 6, 10, 15 um of Al, respectively.  Note that the angular 
range shows up to 15 degrees (larger than the case of the (p,a)).

See entry https://elog.ph.ed.ac.uk/ISOLDE/28 for a full description, but editing the same elog is altering attachment numbers etc.

Here I've added 20 um foil as well as 5.3 MeV/u (~313 MeV) 59Cu beam.

The first set is 59Cu(p,alpha)56Ni showing 56Ni in the heavy ion detector, with different beam energies and Al degrader foil thicknesses.

The second set is for 59Cu(12C,12C)59Cu scattering.

Placed a hand held rad monitor near the faraday cup and took rate readings every 20 seconds, right after inserting the gate valve in front of SEC:

Then fitted this for half life.

Assuming a steady state background of 70 cps, and using the first 7 data points... the half life comes out as 82.1 +/-3.9 s.

Excellent agreement with known halflife of 59Cu.

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.  

work in progress.

ACCIDENT Registered on Sunday 09/04/17 ~10 am:
Power went down due to wiring problem
Tom C. closed valves, but chamber was probably already vented to atmosphere. 
During power shut down roughing and turbo pump slowed down and turbo probably deaccelerate against atmosphere.
Possible back flows.
