Hit Carryover: Updates on offline analysis 20mSpeaker: Ryotaro Koike[Ryotaro: Hit Carryover: Updates on offline analysis]- An ill filter was in a private analysis code but not in the default code.- Recovering process will not require bco_diff peak.- Black points are completely same as blue points. Need to fix and update the plot.- To make ratio between blue and black points, you can try 25 (or 30)<BCO<80 to check the ratio become flat or not.-- If it become flat, we can cut the small interval region. It is better than the overcorrection.- Normalization factors for blue and black points are different but the procedure to estimate the factors is same.- In slide 7, still not sure about the cause of the distinctive structure.- The carryover hits include hits from other crossings.- What is the rate of this data?-- Try to check multiple runs with different rate. Maybe several runs from one good store.

INTT commissioning for pp run 20mSpeaker: Yuko Sekiguchi (RIKEN)[Yuko: INTT commissioning for pp run]
- The pp commissioning data were taken in the local mode.- About the problematic 3 ladders on INTT2, talked to Rachid and decided to leave it for now to see if the condition get better tomorrow.- We won't have a chance to access to the bore.- The right plot in slide 3 shows data before masking.-- 3 hot chips may cause the other chips empty. Worth trying to mask after checking status tomorrow.- INTT2 server's high temp issue should be irrelevant to the crazy hot chip issue.- We can increase the threshold only for crazy hot chips but need to communicate with the chips at least.-- Do we have a script to change the threshold only for some particular chips?-- So far we have only used one threshold for all chips, and masked chip is it is so noisy to cause DAQ issue.- INTT local team will investigate and decide how to avoid the noisy chips tomorrow morning.- One possibility of INTT2 issue is one of the optical driver is dying.-- List up all of the possibilities.-- Suspect that the FPGA or optical driver is not getting enough voltage.-- Increasing the voltage for FPGA or optical driver is impossible because those are after regulators.-- Worth trying to swap cables at Felix side?- Timing alignment between all INTT servers need to be checked. -

Plot preparation for INTT Barrel NIM 20mSpeaker: Cheng-Wei Shih (National Central University)
[Cheng-Wei: Plot preparation for INTT Barrel NIM]
- The collision data doesn't have radial restriction, which must have a bigger errors.-- It would be nice to have cosmic data with millipede to have additional constraint.- Radial shift from the geometrical calibration using collision data is not so accurate, so you can remove radial direction vectors, then show shifts only circular direction.- For the bco peak study, please double check it by removing some problematic ladder which show some periodic spike other than the collision peak.- An editorial meeting will be held next week. Plot to be prepared in December. Rachid already wrote his part. -
