Thu Nov 23 13:16:56 2017, CLW, Beam energies
|
Beam energy measurements can be found in the electronic logbook for ISO-REX-HIE
https://op-webtools.web.cern.ch/elogbook/
measurements for all energies were: |
|
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 |
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. |

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 |

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 |

Header: 4.7 MeV/u and C_09. PS back, but need to check how much beam actually there was before next issue
Ender: no beam at our sample; IHS cavity (part of normal conducting linac) tripped
