Minutes of the forward endcap EMC meeting, 25th of September 2023, 14:00 - 15:15

First biweekly Meeting Related to COSY Beam Data Analysis:

• Bonn ansatz for data analysis, final pi0 caibration of the FWEC:

1. Time calibration (see Endcap-Analysis-Meeting_20230925_Frenkel.pdf)
2. Basic MIPs calibration
3. Using Ben's clustering script
4. Pion peak retrieval

• Time calibration via forced 1 Hz trigger events insufficient; clocks of the FPGAs drift non-linear
• No linear fit possible, instead interpolation between adjacent time stamps
• Time calibration resdiuals then become linear

Work at COSY:

• Lukas prepared copying of last beam time data (new hard disks installed in Juelich), remaing time to finish about 3 days
• Access to TOF-hall from mid of next week on (beam until Oct. 4th)
• Once access we should find the origin of the light pulser Q4-problem of delayed triggering, Bonn and Bochum colleagues needed, should agree upon a suitable date

Organisational:

• Software repository available in Bonn, should be used
• Analysis on ntuple, CB-Elsa software, PANDA-Root? -> PANDA-Root has 'feature extraction' functionality, Celina and Ben have some experience using PANDA-Root
