Wed Sep 25 13:03:46 2019, Laszlo, Analysis, simulations on 118Te+p, 11x
|
I have made some simulations at 8AMeV, 7AMeV and 4AMeV energies for the main 118Te + p reaction channels. For the
Rutherford simulations credits to Yuanming! For each energy there are 3 simulations: without the scraper, with the
scraper (online), scraper (online) + E-truncation (offline). The scraper is treated as an "ideal scraper" meaning

Fri Mar 20 13:21:33 2020, Jan, Laszlo, Analysis, 124Xe data of first night,
|
The unpacked data of all runs from the first night (46-50) is located at
litv-exp@lxg0188:/data.local2/E127_lmd/124Xe_1st_night.root

Sat Mar 21 23:19:14 2020, Jan, Analysis, 118Te52+ on H2-target - Xray spectrum 90 degree,
|
The attached spectrum is for the 90 degree X-ray detector taken for about 3 hours with 118Te52+.
We see two peaks at ~29 keV (K-alpha) and 44 keV (K-REC).

Sun Mar 22 01:36:14 2020, Pierre-Michel, Analysis, Target overlap, 10x
|
Here are the data file for the rates of the recoil detector for different values of the target bump. The average rate over background is proportional to
the target overlap.

|
Mon Mar 23 13:26:59 2020, Jan, Analysis, runs_90to99 SCRAPER RESULTS,
|
With scraper, we have roughly 150-200 (p,g) counts now.
X-rays look fine! |
|
Mon Mar 23 14:32:03 2020, Jan, Analysis, runs_100to104 NO-SCRAPER RESULTS,
|
Without scraper, we have very few (p,g) counts, hard to get numbers quickly, maybe ~50.
X-rays look fine! |

 Fri Nov 20 15:53:37 2020, Jan, Analysis, Test of 2nd DSSSD (gen2), 2021
|
Here is the analysis of the test runs with the 2nd DSSD (gen2) using the quick_si_plots.c script attached.
All 32 Si channels are working with acceptable performance.

Fri May 21 01:17:37 2021, Laszlo, Analysis, simple analysis code, 2021
|
//a simple code (template) for offline analysis
//made by Laszlo, serves as a simple demonstration for enthusiastic shifters
//it creates a "no double counting Si 2D pos" histo

Tue May 25 11:58:30 2021, Jan, Analysis, 118(p,g) counts until run0115, 2021
|
The two attached plots show the collected Si data up to run0115.
Within this ~15h we have about ~70 counts in the peak region.
|
|
Wed May 26 14:28:23 2021, Jan, Analysis, Xrays from 118Te & 124Xe, 2021
|
Attached is a plot of the uncalibrated energy spectra taken with the 90 degree xray detector for 118Te (red) and 124Xe (blue).
Shown is the region covering the K-alpha and K-REC peaks.
|
|
Fri May 28 15:15:06 2021, Jan, Analysis, 118Te(p,g) counts runs 135 to 174, 2021
|
This is the summary of all Si data collected at 6 MeV/u until run174 before the Alvarez problem.
We have roughly 50-60 counts in the peak region.
This data corresponds roughly to 36hours of beam, which means ~1.5 to 2 counts/hour. |

Fri May 21 10:00:51 2021, Jan, Accelerator, target bump, 2021
|
The target overlap was optimized on xray and si rates.
The setting now is -10mm in SC9 |

Tue May 25 07:51:48 2021, Jan, Accelerator, ESR stacking cycle length, 2021
|
The full cycle length of ESR with 30 stacks is about 7:45 minutes, out of which 15.5 sec are with target switched ON.
This is without CMB/HTD in parallel. |
