Straw bi-weekly meeting
Michal K.:
- FCC-ee tracking workshop next week (16-20.11.2026)
- not clear if a straw detector is still considered and a good option for Allegro
- new student is joining to work with Zdenko on cluster counting using ML
Michal Z.:
- lab in b1 is ready, the gas is available, one valve needs to be replaced (5 bar -> 3 bar)
- the portable CO2 detector has to be on while working with gas
Hans:
- need to log temperature and humidity to understand how the system works
- idea: send end caps to Dubna to pressurize the straws right after production, need to think about how to transport them
Zdenko:
- are the straws cleaned on the inside? -> Hans: no, they are only flushed with Ar
- there are dents in straws in the intermediate prototype - could that cause strange signals that we observe?
- we could use 2 Lamina and 2 Dubna straws without any dents in the short prototype
