Tue Nov 20 14:07:37 2018, dk, Blue Loan Book Scan 
|
Scan is attached, including all items denoted in the loan book as being taken to ISOLDE.
This will be useful for a complete compilation of our inventory. |

Mon Nov 12 11:25:58 2018, CBH, Expected Proton Energy Plots
|
Attached are the plots from MC simulations of the energies the detected particles are to have, with the top plot showing the dE-E plot and the bottom
plot showing the total energy of the particles.
Please note the height of the peaks is not indicative of the counts expected and there is a low proton background expected between the entrance |

Thu Nov 8 10:01:32 2018, CBH, DK, New Struts Installation 8x
|
Struts arrived and were installed on Wednesday. The holes on one side of each of the struts to connect the wheels to were slightly too wide (11.5
cm vs 10.5 cm).
We've taken away part of the wheel holders and now they seem to be fitting in. |

Wed Nov 7 14:27:45 2018, CBH, DK, Beam Plan for Miguel and Alberto (ISOLDE beam operators)
|
Presently, we are scheduled for 9 days:
Nov 26-28
are three (3) days nominally for beam development
Nov 29-Dec 4 are six (6) days nominally for physics data taking
Dec 5-6: Shutdowns and important
tests are planned by ISOLDE team
Dec 7th - power gets shut off to ISOLDE
==Run Plan==
1 day for ion source and 2.8 MeV/u beam dev
1 day for High |
|
Mon Nov 5 16:26:34 2018, DK, CBH, Draft run plan

Please see https://elog.ph.ed.ac.uk/ISOLDE/203 for the E_cm calculations.

Mon Nov 5 13:52:46 2018, CBH, CoM energies for 44Ti(alpha,p) reaction for different entrance windows and beam energies
|
Assuming 200 Torr helium target., elastic and reaction peaks do not have signifcant overlap unless stated:
3um Ti, 1.88 MeV/u beam: Ecm=4.27-4.58 MeV
3um Ti, 2.2 MeV/u beam: Ecm=5.50-5.80 MeV |

Wed Oct 31 16:01:33 2018, DK, Measuring foil thickness
|
A couple scans from my notes which may be useful.
One discusses alpha energy loss in nominal kitchen foil (~12 um) and also introduces my technique to calibrate a thin (~20 um) SSD. Sorry I forget which |

(Wrapped up)
Cell b : 15um Al exit, 12.5um Al entrance. L/R ~0.4Torr/hr overnight (in vacuum)

Tue Oct 9 10:40:13 2018, DK, To-do Meeting Notes: July, August, September, October 6x

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.

Mon Oct 8 12:07:18 2018, DK, Gas cell check with He sniffer
|
Notes from an email:
Tested the chamber with the leak checker. We got 3.7 x 10^-6 mbar
|
|
Mon Oct 8 12:05:25 2018, DK, PB, Gas cell supports
|
These are used to connect the gas cell to the target ladder. We only had the one, and it would be more convenient if each gas cell has its own, to avoid
swapping them back and forth.
