Thu Sep 14 08:37:27 2017, Claudia, Detector installation 8x
|
dE detector: 2083-9, 74 um thick, V_depletion=12V; V_operating=24 V
E detector: 3080-23, 1012 um thick, V_d=110; V_o=350 V
HI detector: 2410-23, 65 um; V_d=7 ; V_o=14 V |

ADC#1 0-31: p+n dE
ADC#2 32-48: n+n dE
ADC#2 49-64: p+n dE |

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

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 |

Sat Nov 11 07:45:34 2017, Claudia, Checking Laser quality
|
There is an option to see when the beam is gone if it is due to lasers or due to the accelerator.
- window next to proton requestion switch
- put middle faraday cup in |

Wed Nov 8 23:46:32 2017, Daid, Charge State Distributions
|
Faraday cup readout at the end of our chamber should change based on whether or not the target is in and also the 59Cu beam energy.
The effect could be as much as 10 to 20%. At some point, we should check the Faraday cup reading with the CH2 target and with the empty target. |

ADC offsets calculated using data files R42-r47

|
Fri Nov 10 08:31:06 2017, TD, CAEN V767 TDC trigger/channel 0 logic change
|
Approximately 5-10% of events overnight were 'bad' i.e. missing TDC data
Checked the CAEN V767 trigger/channel 0 logic (without beam) this morning
|
|
Thu Nov 9 17:01:49 2017, TD, CAEN V560 Scalers added to datastream
|
CAEN V560 Scaler channels #0-7 have been added to the EbyE datastream by adding
per event readout of defined VME registers identified as group 31, items 0-15
|
|
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. |
|
Wed Nov 8 22:21:35 2017, Ruchi, Beam transmission
|
By the end of beam tuning (around 6pm), beam transmission between Faraday cups at the end of SEC and at end of Edinburgh chamber:
~100% through 10mm collimator (empty target frame)
> 50% thought 3mm collimator |

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 |
