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.

--text from email--
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)).

==In Edinburgh==
  Target ladder and components

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.

This log entry contains a basic instruction on how to operate the Julabo liquid flow chiller.

There are 5 buttons (left to right): Up/Down, Enter, 1/0.  

To toggle power to the device, use 1/0 (on/off).  NB: This only turns the electronics on, and does not initiate circulation / cooling.

When switched on, it will display sequentially some basic information sequentially.  One may generally ignore these, and wait until it displays the current temperature.

To adjust or check the set point, tap either of Up/Down.  To change the set point, press and hold either up or down.  Release the button when the desired set point is reached, 
and tap up/down to do the fine tuning.

Once the desired set point is entered, the display will return to the current temperature reading.

To turn on circulation / chilling, press and hold Enter (the down/left facing arrow).  One needs to hold this button several seconds.  It is obvious when it begins to operate, as 
it will make more sounds, and additionally the Snowflake LED indicator should turn on (unless the current temperature is lower than the set point, it may simply flash briefly).

The set point can be adjusted while the circulation / chilling is on, as above.

To turn the circulation / chilling off, hold down Enter again for several seconds.

Best to raise the set point to ~20 degrees and wait for it to reach the value, before turning off circulation, and finally the device (0 button).

will watch the scalars but continue the run.  22:14 beam is off.  22:18 the laser tuning is finished.
