'''EEEMCAL IN DETECTOR PROPOSALS'''

* Detector looks similar in all three proposals
:* differences in size and number of PWO vs. Glass
:* there may be differences in attachment - ATHENA and ECCE assume mounting on universal frame; CORE has been assuming mounting to endcap HCAL frame, but recently moved away from it - CORE more sensitive to impact of non-sensitive material regions

* '''ATHENA:'''

:* z = 195cm
:* R_in = 11 cm (eta ~ -3.5) = R_min_PWO
:* R_max_PWO = 53cm (eta ~2) = R_min_Glass
:* R_max_total = 100 cm (eta ~ 1.4) = R_max_Glass

:* Modules PWO = ~ 2200 (2 x 2 x 20 cm3)
:* Modules Glass = ~ 1400 (4 x 4 x 40 cm3)
::* Total weight: ~ 2400 kg

:* If assume all PWO for this volume: 7600 PWO modules
::* Weight ~ 7000 kg

* '''ECCE:'''

:* z = 190 cm
:* R_min = 11cm (eta ~3.5) = R_min_PWO
:* R_max_PWO = 49cm (eta ~2) = R_min_Glass
:* R_max_total = 57 cm (eta ~1.9) = R_max_Glass

:* Modules PWO = 1680 (2 x 2 x 20 cm3)
:* Modules Glass = 160 (4 x 4 x 40 cm3)
::* Total weight: ~1500 kg

:* If assume all PWO for this volume: 2960 PWO modules
::* Total weight ~ 2000kg

* '''CORE'''

:* z = 110cm
:* R_min=8.5cm
:* R_max=47cm

:* Modules PWO = 1412 (2 x 2 x 20 cm3)
::* Total weight ~ 1000kg


'''SIMULATIONS'''

* Tolerance material in front of EMCal - ongoing studies

* e/pi studies ongoing
:* ECCE produced some simulation data samples that are used for these studies

* implementations - completed
:* barrel SciGlass (Nathaly)
:* EEEMCAL Fun4All (Carlos)
:* EEEMCAL DD4HEP (Vladimir/Dmitry)

* ATHENA simulation campaign planned for August
:* Will include hybrid EEEMCal

* ECCE simulation campaign 21 June uses PWO only EEEMcal and sphenix barrel EMCal(?) - does not yet have EEEMcal hybrid or SciGlass barrel
:* hybrid EEEMCal and Sciglass barrel will be in next ECCE simulation campaign

'''DESIGN EEEMCAL'''

* Initial design prepared

* Cooling would be water cooling around circumference plus possible mechanical cooling from the back
:* must also take into account cabling from back

* Beam pipe characteristics around the detector - diameter etc.

* Main questions:
:* beam pipe
:* support limitations at universal frame
:* thickness of outer and inner radius

* Action items:
::* prepare summary of questions
::* discussion with EIC PM

'''PWO+SIPM DETECTOR UPDATE''' 

* Found a way to include 16 SiPM per crystal

* Discussion about services and integration for beam test

* Action item: 
:* prepare list of services needed for discussion with HallD electrical engineer

'''BEAM TESTS 2021'''

:* For DESY tests: Douglas Hasell
:* For JLAB tests: Tanja Horn


'''NEXT MEETING: MONDAY 26 JULY 2021 AT 8:30AM ET'''
