The figure below shows the interface of the program "combine_injection". You can combine any tdms file with this program. To run this 
program, you need to log in to the server /luster/astrum/, and activate the conda environment. Then type the command "combine_injection" at 
the terminal. You will see the interface.

The strongest line is 229Th+89/229Pa+89. The yield and frequency of 229Pa+89 and 229Th+89 are very close to each other.  We needed to 
install Al target to suppress Pa as much as possible. Al gives a better ratio of h-like to he-like than Be. Two peaks at left 
side are 237U+92/237Np+92 and 224Ac+87. One peak at right side is 
234Pa+91/234Np+91. 

Note added 2024-06-14 (Carsten): a) We will not produce Np, this is an artifact of Lise, b) relative intensities are for injection only. Line intensities for  237U/224Ac/234Pa are substantially lower after cooling/HF/deceleration.

The simulated frequency is given in simulation_result.out. The yield is calculated by LISE file. The LISE file is attached here also.

The preliminary identification has been thoroughly checked using the RionID software. We have confirmed that the identification is accurate.

Attached can be found the simulation file with each of the expected ions, their revolutions frequencies in the 125th harmonic and expected yield from the LISE file attached.
Also attached are some figures from RionID that highlight the region of interest for the 124th and 125th harmonics. The center frequency of the 245 MHz resonator is closer to the 124th harmonic for 229Th+89 which is located at 244.769 MHz. 

If necessary, we can slightly shift the resonator curve to higher frequencies to fine-tune the signal-to-noise ratio for 229Th+89.

We changed the dye at ~3pm.

After some fine adjustements of the laser we had to change the MRC settings, because the laser position changed.
Therefore we checked the position of the laser with the T-Scrapers with the settings from post 49 "First Scraper Scan".

New settings of MRC and screen pic is attached.
The position of the laser on the screen is now the 'same' as yesterday (see attachement).
