[EIC-CORE] [EXTERNAL] Re: CORE General Meeting in 35ish minutes

[Jacobs, William W]

Ciao --

  a few comments and a question:

a) I was having trouble during the solenoid coil material/construction
discussion today at the CORE meeting -- Copper vs AL -- because I recalled 
that the Belle folks didn't worry about the mass/rad length (stated as "all 
the tracking and calorimetry is inside the coil" so who cares). 

   Turns out parts of my other memory were right, they did use Al for the coils 
(instead of Cu), as apparently this co-extrusion technology was alive many years 
ago. OTOH, they used a very robust cryostat design made out of stainless steel! 
It is not clear they especially tried to optimize for a low muon threshold ... 
so interesting question for CORE as to inner detectors + coil/cryostat + structure 
mass burden and what could be accomplished.

   Here is article link with some details on Belle 1.5T solenoid construction
https://urldefense.proofpoint.com/v2/url?u=https-3A__link.springer.com_chapter_10.1007_978-2D1-2D4757-2D9047-2D4-5F25&d=DwIFAw&c=CJqEzB1piLOyyvZjb8YUQw&r=aRyZltrEySmLlrFU4Ems83mNJ2sRhhXIX_v6ViWLNFQ&m=edUEpyMIfiEHozlxBz3aTfF3e-Mze6r37Tvip7Ga2kzH45YYebCXqmjTklho2siy&s=bxzIE0sDb9x1jdc38pIMOj_yOFwnq1YsqH0NA85585M&e= 
"Development of a Superconducting Solenoid Magnet System for the B-Factory 
Detector (BELLE)". You will need some library connection to get past 
Springer "pay wall" => I can send a personal copy if someone interested/requests.

b) fyi ... the latest Belle II KLM upgrade thinking now includes investigation
of other possible strip readout modes (besides embedded fiber into SiPM) in order
to improve timing response (TOF?). 

c) questions: in the CORE proposal to a joint EIC NIM publication, is there a 
chance/plan to put proposal itself on arXiv soon? A scan of e.g., a recent ECCE 
meeting agenda reveals plans to publish lots of other stuff besides their
detector proposal itself. If all this goes into some NIM "collection" (there might 
be also other CORE, etc.?) and it is all to be reviewed bla bla bla, this could 
stretch out for quite some time and come after user and other topical meetings 
where CORE detector info might be important.

                                             Thanks,
                                                     -- Will j.
