- Other
PARTICIPANTS: Bert Metzger, Rolf Ent, Amy Comer, Bogdan Wojtsekhowski, Hamlet Mkrtchyan, Hovanes Egiyan, Igor Strakovsky, Josh Crafts, Steven Lassiter, Vitaly Baturin, Dean Spiers, Tanja Horn
DESIGN/ENGINEERING OVERVIEW (Steven L.)
- 486 W blocks on site
- Coil procurement
- specification created - in discussion with TOKIN about specification and tolerances
- in discussion with TOKIN about specifications and tolerances - concerns about stated tolerances applied to geometric dimensions on flatness and parallelism; conductor cleaning
- CPS Tosca model updated to include bolt holes and cutouts
- Prototype (Dean)
- on site, machined and assembled
- Working on reqs for yoke and pole
- Yoke: 1010; pole: supermendur
- working towards deadline - beginning August for end of year clearance
- Insulation material and radiation hardness
- glass resin made for Japanese magnet
- max expected is MRad, but material should be resistant up to GRad levels
- Started discussions with Hall D about design models
MAGNET DESIGN/ASSEMBLY (Bert)
- Drawings almost done for yoke and pole
- identifying vendors
- Assembly steps outlined
- transport stand
- fasten coil to side yoke and shim; install
- fasten lower yole to stand
- check gap on coil
- add shims - mm of clearance to be accounted for
- fasten lower absorber - using alignment pins
- fasten side yoke assembly
- side yokes installed; fasten upper shielding
- check gap on coil and upper shield blocks, add shims
- add upper absorber and springs - still need to figure out pressure
- add flags to leads
- ready to be shipped to hall and can crane in place
- Testing cooling paths on 3 different models (see below)
- Clearances
- W blocks and cutting for special shapes
- Drawings for yoke assembly expected to be done in about a week
- Survey adjusters to align magnet; fine tuning with beam
- Length of leads will depend on amount of shielding - Gabriel is working on that
- Action item:
- check with Gabriel on status of the simulations
FLUENT CALCULATIONS - WATER COOLING CHANNEL ANALYSIS (Amy)
- Goal: compare Fluent compuration to by-hand for verification
- investigating 3 major designs with multiple cases
- results are very encouraging - ongoing work to interpret the details
NEXT MEETING: FRIDAY AUGUST 19 AT 8AM ET
