Meeting ID: 872 7116 4194
Passcode: EICTOF22

PED:
Matthew is waiting for inputs from Purdue to finalize the BTOF module PED request. Mathieu will prepare a similar request for FTOF module.

FTOF geometry:
Wei needs inputs from Andy. Will follow up with him 

TOF in Tracking:
John: are BTOF hits included in ACTS? ZY: yes believe so

TOF in PID:
Zhangbu​​: What is the status of TOF PID LUT?
Oskar: modified reconstruction code to be able to produce the LUT, waiting for the format. Plan to implement own factory and provide output from the LUT

TOF DSC: 
Unanimously accepted the new DSC leadership structure, with Zhangbu as the DSL, Satoshi as the Deputy DSL, Mathieu and Matthew as the two DSTCs. 
Zhangbu: like the technology, has been working on STAR TOF in the last 20 years, ePIC TOF connect to physics interests. Move to KSU this week, will have new students/postdocs to contribute to ePIC TOF.
John/Silvia: DSCs choose own leaderships. Just need an email from the TOF DSC to inform the change, and will make announcement to the collaboration. 

TOF DSC working groups:
Tonko suggested to have two coordinators for mechanical/cooling. Zhangbu/Zhenyu seconded it.

PreTDR for TOF (CD-2): 
John: take electronics as an example
Zhenyu: yes we will discuss within the TOF DSC on the to-do-list, and present our plan at the various meetings

Sensor irradiation:
Simone: FNAL ITA may be available in mid March
Zhenyu: So you will check effects on leakage current, breakdown/full depletion voltage, gain, charge sharing?
Simone: IV/CV tested on all HPK sensors, and laser on some of the HPK sensors. Will use laser to check the gain comparing devices w/o and with being radiated. 
Wei: the anticipated fluence at this campaign are higher than what we will see (1e12 neq/cm2 max). What is the plan if we see effects?
Simone: will look into more irradiation campaigns at lower fluences if effects are seen at 1e13 neq/cm2
Simone: Are there more HPK sensors available?
Zhenyu: yes
Zhangbu: STAR as the last resort to perform such tests. See https://arxiv.org/abs/1310.2495 neutron flux in the ePIC hallway (STAR)
