Thu Jul 27 11:25:35 2023, Claudia, Al-26 planning meeting summary
|
Start 9th August, access to EAR-2 11 am earliest but can start in rack area before
Setup to be used: 1 dE (16 strips, 20 um thickness)
+ 1 E (16x16 strips, 150 um thickness. We have a spare for each thickness
Sample and detectors to be mounted on the same flange
Things
to check: |
|
Fri Aug 11 08:41:31 2023, Annie, Al target & chamber set up 15x
|
| Phtotos of the front & back of the Al target and what it looked like once mounted and in the chamber. |
|
Mon Mar 25 12:57:30 2024, Clw, Adapters for ntof setup
|
| 10 new Adapters for lemo to bnc on my desk |
|
Thu Sep 12 11:07:29 2024, Nick, 40K Borrowed Items
|
We borrowed from n_TOF:
1x O-ring for circular side-flanges on the chamber (the borrowed part has a small green marker cross on it)
10x LIMO-to-BNC connectors (BNC female) from electronics lab outside EAR1 |
|
Mon Sep 16 12:36:45 2024, TD, 34-way IDC to 37-way D connector ribbon cables
|
The 2x sets of 34-way IDC to 37-way D connctor ribbon cables used at GSI for the two-alpha decay measurement have been located - see attachments 1-4.

|
Wed Sep 27 09:54:06 2023, Emmanuel, 10B sample in
|
We switched from Aluminium target to Boron Target (number 1) on Tuesday (26th of Sept.). The Aluminium target was placed in the material room
by the RP. We will change to LiF (number 3) on Thursday (28th of Sept.) |

|
Leakage before take down:
|
|
Fri Oct 16 16:01:41 2015, Sarah Lonsdale, 08/10/15 Removed source and sample, leakage current check
|
Removed source and removed Li sample for blank frame test
|
|
Fri Oct 16 15:56:01 2015, Sarah Lonsdale, 07/10/15 Alpha source in, change to pulser delay 6x
|
Alpha source in - containing 148Gd, 241Am, 239Pu, 244Cm (4x 1kBq)

Fri Oct 16 15:41:14 2015, Sarah Lonsdale, 06/10/15 Changes to DAQ and pulser settings
|
Pulser out of 5,6,7 EFED- extended to 32ms

Mon Oct 12 11:50:52 2015, Sarah Lonsdale, 05/10/15 Pulser, Wiring information and DAQ initial set up
|
| 600mV in 50ohm coax with 25 hz pulser (positive signal) - see 2015-10-05_15.19.54.jpg |
|
Mon Oct 12 12:04:51 2015, Sarah Lonsdale, 05/10/15 Photo of detector distances and layout 8x
|
Fairly self explanatory, note that images with time-stamps before 13.08.29 were taken before fitting the o-ring on the flange and therefore lateral positions
will be different to photos after 13.08.29. Individual detector heights were not changed. |
|
Mon Oct 12 12:07:24 2015, Sarah Lonsdale, 05/10/15 Changes to DAQ settings
|
Note that detailed DAQ information available from project-ntof.cern.ch erunbook ear2.
As a rough guide: |
