12:05 → 12:25 DD4hep discussion

Questions to Software WG

reading through questions.

it is easy to switch to DD4hep.

eventually we will do DD4hep.
if you are doing fun4all, then we will translate it for you.
if you start from zero, start from DD4hep.

issue of timing, issue of synergies.
we now decide to diverge, there will be an impact on availability of experts. if they have to support different proposals, then someone is going to be out. 

what is the cost moving in DD4hep now?

Tom: if I send you a cartoon you will make it in DD4hep? yes. but given we are not experts we cannot take responsibility.

mRICH has final design on GitHub.
instead of code it is better clearer directions and details.

people get in touch with SWG and they will be the contacts

Elke: for some components we have alternatives that we want to integrated. different space needs. how to do apple to apple comparisons? cases where in one case you have full details (and structure) and in other cases it is a detector floating in the air.

Greg: supporting parting DIRC from standalone to fun4all. Impossible that it will work simply via email exchange.

reach out the developers and next week we hear what showstoppers appear.

12:05 → 12:53 Roundtable updates

Updates from the main efforts with details about the progress in the activity. Please, be short and prepare a few (maximum three) slides focusing on what has been achieved since the last meeting.

12:05 DIRC

Speakers: Grzegorz Kalicy (CUA), Joe Schwiening (GSI)

12:08 mRICH

Simulation & performance studies

Speaker: Murad Sarsour (Georgia State University)

12:11 dRICH

12:17 Low momentum PID with TOF

Speaker: Wenqing Fan

12:20 B field impact on forward RICH

Speaker: Chandradoy Chatterjee (INFN Trieste (IT))

do you have any feeling why it went in the wrong direction?

differences are small.
if you look at the B field maps, there is no much diff. in the fRICH region.

12:23 DAQ

Gathering DAQ requirements from PID WG

Speaker: Alexandre Camsonne (JLAB)

DAQ_PID_June7th_2021.pdf

12:26 LGADs for TOF-PID

simulation & performance studies, design, cost estimate etc.

Speakers: Shuai Yang (Rice University), Prof. Wei Li (Rice University)

Status of LGADs TOF simulations.pdf

12:29 SiPM for RICH optical readout

R&D on SiPM as an option for the readout of the forward RICH

Speaker: Roberto Preghenella (INFN Bologna)

12:32 Pressurised argon for the gaseous RICH

mechanical studies and simulations for a pressurised argon vessel for the forward gas RICH

12:35 LAPPD option for photon readout

R&D on LAPPD detectors must not be forgotten

Speaker: Silvia Dalla Torre (INFN, Trieste)

12:35 → 12:55 Presentations

This is time devoted to a longer discussion with a presentation of work done or to be done, if there is any and if there is the need for that.

12:55 → 13:00 AoB

In case there is any other business to discuss, we can take it here. If discussion takes longer than 5 minutes, it means that it needs a proper space and will be point for next week.
