* Engineering analysis and planning
    
* TCS updates

* Other


PARTICIPANTS: Amy Comer, Bogdan Wojtsekhowski, Brannon Semp, Donal Day, Deb Biswas, Hamlet Mkrtchyan, Hovanes Egiyan, Steven Lassiter, Marie Boer, Rolf Ent, Vardan Tadevosyan, Yeranuhi Ghandilyan, Tanja Horn

ENGINEERING/DESIGN

* PR sent out for magnet steel, coil, etc.

* Prototype
::* waiting on electrical work and some monitoring and control interface development 
::* planning tests this fall

* Presentation on status of CPS at Hall D meeting
::* will circulate draft talk for comments/feedback


FLUENT MODEL

* Model consistency checks
::* coordinate systems needed to be made consistent between Bogdan/Gabriel FLUKA model and Fluent

* Working on next iteration - need to make consistent mesh with Fluent
::* one approach: for each point (x,y,z) in table need power deposition - need to find points that are nearby in Fluent model representative then do interpolation
::* another approach: remove all not relevant points (those that give zero results)

* Note: good to make models consistent from the start


HALL D CPS DESIGN

* Longer design (3m) with longer magnetic field (2T)

* Planning fo finish conceptual design and hold a design review in Winter 2022/23, then begin optimization

* Main person working on design: V. Baturin


FLUKA SIMULATIONS

* power deposition in copper block is complete
::* scale beam power as needed - power deposition proportional to beam power

* simulations for shielding are ongoing


REMAINING DESIGN AND OTHER

* remaining shielding
* plastic
* final design absorber
* infrastructure list including moving experiment downstreams (assumed operations)


PLANS FOR TCS PROPOSAL

* In approach towards submission of a TCS proposal consider addressing PAC concerns on the experiment
::* see PAC report - detailed technical concerns are listed there

* Polarized TCS science case seems good - no need to change at least not right away

* Discussion about path forward - major item: make a plan for addressing PAC concerns in coordinated way


NEXT MEETING: FRIDAY 14 OCTOBER AT 8:00AM ET
